Environmental Education (EE) is increasingly relevant in the current context of environmental crises, requiring approaches that integrate Human Ecology (HE) and Environmental Psychology (EP) due to understanding the interdependent relationship between ecological and human systems. This study emphasizes corporeity as a fundamental dimension for reconnecting humans with nature and fostering ecological awareness. The study aimed to develop and evaluate a transdisciplinary intervention project based on bodily experiences with children and adolescents in a Brazilian public school, aiming to improve their connectedness with nature and ecological values. A diagnostic survey was conducted with 103 students aged 10–13 years, including open questions, and two instruments: the Inclusion of Nature in Self (INS) and the Values for Pre-adolescents scale (EVP). The results indicated that one 5th-grade class, which presented the lowest self-transcendence mean (4.07), was selected for pedagogical interventions. In the second stage, 20 students participated in workshops held in public parks and a school green area, combining sensory awareness and playful activities. The findings suggest that these experiences stimulated pro-environmental attitudes, including group care for nature, protective behaviors, and positive emotions such as peace, happiness, and freedom. Despite the small sample size, the results highlight the importance of strengthening embodied experiences in natural environments, increasing frequency and intensity to support the development of ecological values and deeper connectedness with nature.

This study assessed exposure to silver (Ag) in children and adolescents living in Alcalá de Henares, an urban-industrial city in the Madrid Region (Spain), in light of the growing use of Ag in consumer and medical products. Scalp hair was collected from 120 children (6–9 years; 70 females) and 97 adolescents (13–16 years; 68 females) permanently residing in the city, and Ag concentrations were determined by inductively coupled plasma mass spectrometry under strict quality control. In parallel, 97 topsoil samples from urban parks were analysed to evaluate potential environmental sources, and risks of non-carcinogenic exposure via ingestion and dermal routes were characterised. Median Ag levels (µg/g) were 0.1205 in girls and 0.0892 in boys among children, and 0.1057 and 0.0387 among adolescent females and males, respectively. No significant differences were observed between age groups (p = 0.153), but females showed consistently higher levels than males. Proposed reference intervals (CI-PP95) were 0.2866–0.5383 µg/g for children and 0.5248–3.0795 µg/g for adolescents. Hazard quotients for soil exposure were below unity, indicating minimal health risk. Overall, Ag exposure in Alcalá’s youth was low and consistent with background levels in non-occupationally exposed populations. The higher values found in some female adolescents likely reflect lifestyle-related sources. These results provide the first local reference values for Ag in hair of Spanish children and adolescents, offering a baseline for future biomonitoring and temporal trend analyses. Full article

Background/Objectives: This study aims to understand gaps and strategies in Chinese Americans’ utilization of SDOH services in the pediatric primary care context in Sunset Park, Brooklyn, from a patient–provider partnership perspective. Methods: The study was guided by an integrated Patient–Provider Partnership, Engagement, and Collaboration (PEC) framework that influenced patient–provider interaction during the provision of SDOH services. A qualitative study design was applied, and eight quality improvement interviews with healthcare providers were conducted to understand the existing community and health service system context. Six in-depth interviews were conducted with Mandarin-speaking Chinese American caregivers. Interviews were transcribed and coded in Mandarin and then translated into English. Results: Consistent with the PEC framework, we identified cognitive, affective, and communication gaps from both the patient and provider. Caregivers reported unaddressed needs in food, financial security, and mental health. Providers identified gaps in patient workflow, staffing, and the intake form process. Conclusions: Addressing social determinants of health among Chinese American immigrant populations is crucial for mitigating poor health outcomes in children and families. Multi-level community-engaged strategies are needed to alleviate the challenges facing this community. Recommendations for future research should consider the importance of language and cultural affinity, digital intake forms translated into the patient’s language, and regular on-site staffing during SDOH screenings.

Surface dust serves as a significant carrier and potential source of various pollutants in urban environments. However, limited attention has been paid to toxic metals in underground parking garages’ (UPGs) surface dust. In this study, thirty surface dust samples were collected from UPGs to determine the toxic metals contents, their risk and disease burden to local residents, and their potential source. The mean contents of V, Cr, Co, Ni, Cu, Zn, Cd, Sb, Pb, Hg, and As were 68.06, 126.48, 8.73, 27.68, 76.25, 287.07, 0.74, 4.28, 172.67, 0.24, and 8.66 mg/kg, respectively. Accumulation index revealed that the geoaccumulation index of Cr, Cu, Cd, Zn, Sb, Pb, and Hg ranged from 0.52 to 1.85. Pollution load index verified that the surface dust was slightly (56.67%), moderately (30.00%), or heavily polluted (13.33%). Risk assessment revealed that the total non-carcinogenic risks for children all exceeded the acceptable level (HI > 1.0). Notably, the carcinogenic burden reached 12.9 disability-adjusted life years per 100,000 population, with Cr contributing 84.1%. Furthermore, these toxic metals mainly derived from vehicle-related activities, use of coal, and the aging of decoration materials, and their accumulation in UPGs’ surface dust was almost unaffected by the essential conditions of residential areas.

Background/Objectives: Leisure participation is vital for children’s development and family inclusion, yet families of children with developmental delays and disabilities face significant barriers. Guided by a health literacy framework, this study examined how personal and organizational health literacy shape access to inclusive leisure opportunities. Methods: Semi-structured interviews were conducted with 14 caregivers of young children (aged 2 to 6 years) with developmental delays and disabilities. A qualitative content analysis was applied to identify family and environmental factors shaping leisure participation. Results: Families with stronger personal health literacy engaged in diverse leisure activities, prioritizing children’s development through park visits and structured home routines. In contrast, weak organizational health literacy—reflected in limited inclusive facilities and support systems—restricted opportunities, increased caregiver stress, and forced adaptations such as traveling farther or rescheduling activities. These barriers underscored families’ vulnerability to exclusion while also highlighting their resilience in navigating daily life. Conclusions: This study demonstrates that health literacy functions at both personal and organizational levels to shape leisure participation. Beyond identifying barriers, it shows that leisure is intertwined with developmental needs and school readiness. By applying a health literacy lens, the study contributes to understanding family dynamics in inclusive leisure and underscores the need for responsive community services and inclusive policies.

Agricultural soils near industrial parks in the Yellow River bend region face severe heavy metal pollution, posing a significant to human health. This study integrated field sampling with laboratory analysis and applied geostatistical analysis, positive matrix factorization (PMF) modeling, and health risk assessment models to systematically investigate the pollution levels, spatial distribution, sources, and ecological health risks of heavy metals in the area. The main findings are as follows: (1) The average concentrations of the eight heavy metals (Hg, Cr, Cu, Pb, Zn, As, Cd, and Ni) in the study area were 0.04, 48.3, 54.3, 45.7, 70.0, 22.9, 0.4, and 35.7 mg·kg⁻¹, respectively. The concentrations exceeded local background values by factors ranging from 1.32 to 11.2. Exceedances of soil screening and control values were particularly pronounced for Cd and As. Based on the geoaccumulation index, over 75% of the sampling sites for Cr, Pb, Zn, and Cd were classified as moderately to heavily polluted. Potential ecological risk assessment highlighted Cd as the significant ecological risk factor, indicating considerable heavy metal pollution in the region. (2) Kriging interpolation demonstrated elevated concentrations in the western (mid-upper) and eastern (mid-lower) subregions. Pearson correlation analysis suggested common sources for Cu-Pb-As-Cd and Cr-Zn-Ni. (3) PMF source apportionment identified four primary sources: traffic emissions (38.19%), natural and agricultural mixed sources (34.55%), metal smelting (17.61%), and atmospheric deposition (10.10%). (4) Health risk assessment indicated that the non-carcinogenic risk for both adults and children was within acceptable limits (adults: 0.065; children: 0.12). Carcinogenic risks were also acceptable (adults: 5.67 × 10⁻⁵; children: 6.70 × 10⁻⁵). In conclusion, priority should be given to the control of traffic emissions and agriculturally derived sources in the management of soil heavy metal contamination in this region, while the considerable contribution of smelting activities warrants heightened attention. This study provides a scientific basis for the prevention, control, and targeted remediation of regional soil heavy metal pollution. Full article

Increased precipitation and extreme weather due to climate change can remobilize recent and legacy environmental contaminants from soil, sediment, and sewage overflows. Heavy metals are naturally distributed in Earth’s crust, but anthropogenic activity has resulted in concentrated emissions of toxic heavy metals and deposition in surrounding communities. Cities around the world are burdened with heavy metal pollution from past and present industrial activity. The city of Camden, NJ, represents a valuable case study of climate impacts on heavy metal mobilization in stormwater runoff due to similar legacy and present-day industrial pollution that has taken place in Camden and in many other cities. Various studies have shown that lead (Pb) and other toxic heavy metals have been emitted in Camden due to historic and recent industrial activity, and deposited in nearby soils and on impervious surfaces. However, it is not known if these heavy metals can be mobilized in urban stormwater, particularly after periods of high precipitation. In this study, Camden, NJ stormwater was collected from streets and parks after heavy rain events in the winter and spring for analysis with inductively coupled plasma-mass spectrometry (ICP-MS) to identify lead (Pb), mercury (Hg), cadmium (Cd), and arsenic (As). Lead was by far the most abundant of the four target elements in stormwater samples followed by Hg, Cd, and As. The locations with the highest Pb concentrations, up to 686.5 ppb, were flooded allies and streets between commercial and residential areas. The highest concentrations of Hg (up to 11.53 ppb, orders of magnitude lower than Pb) were found in partially flooded streets and ditches. Lead stormwater concentrations exceed EPA safe drinking levels at the majority of analyzed locations, and Hg stormwater concentrations exceed EPA safe drinking levels at all analyzed locations. While stormwater is not generally ingested, dermal contact and hand-to-mouth behavior by children are potential routes of exposure. Heavy metal concentrations were lower in stormwater collected from parks and restored areas of Camden, indicating that these areas have a lower heavy metal exposure risk. This study shows that heavy metal pollution can be mobilized in stormwater runoff, resulting in elevated exposure risk in industrial cities. Full article

Natural playgrounds have garnered growing attention as supportive environments for children’s mental health. This study develops an analytical framework grounded in affordance theory and incorporates the Pleasure–Arousal–Dominance (PAD) model to examine the relationships between physical environmental features—and their combinations—in natural playgrounds and children’s emotional perceptions. Using the Yunhu Natural Playground in Fuzhou, China, as a case study, we selected seven typical behavior setting units. Environmental features were assessed through UAV imagery and on-site observations, while PAD-based visual questionnaires were employed to collect emotional responses from 159 children. By applying correlation analysis, random forest, and regression tree models, this study identified key environmental predictors of children’s emotional responses and revealed heterogeneous mechanisms across the three emotional dimensions. The results indicated that seasonal flowering/fruiting plants, accessible lawns, and structured play facilities were critical in supporting children’s pleasure, arousal, and dominance. Specifically, pleasure was primarily associated with sensory enjoyment and contextual aesthetics, arousal favored open grassy areas, and dominance was linked to environments with clear structure and manipulability. Based on these findings, this study proposes a spatial configuration strategy characterized by “nature as foundation, play encouraged, and structure clarified” to promote the positive development of children’s multidimensional emotional experiences. This research contributes empirical evidence on the role of physical environmental features in supporting children’s play behaviors and expands the theoretical understanding of the “emotional effects” of green spaces. While the findings are exploratory and context-specific, they emphasize the critical role of the sensory–behavioral–emotional chain in shaping children’s well-being and provide theoretical and practical guidance for the design of emotionally supportive, child-friendly, natural play environments in schools, parks, and residential areas.

Although trap-neuter-return (TNR) is a popular method for managing free-roaming domestic cat populations, a common criticism is that sterilization fails to mitigate the public health risks posed by free-roaming cats. One of these risks is the environmental contamination of Toxoplasma gondii, a parasite that can be spread in the feces of actively infected felids (both domestic and wild). In healthy humans, toxoplasmosis tends to be mild or asymptomatic; however, the disease can have severe consequences (e.g., for pregnant women) and even be fatal in immunocompromised individuals. Previous research has examined the extent to which free-roaming domestic cats might contaminate sites frequented by young children (e.g., schools and parks). However, the model used included several assumptions that are not reflective of sterilized cats in an urban setting (e.g., smaller home range). By properly accounting for several key factors (e.g., reproductive status, home range), our modeling revealed considerably lower rates of potential incursions by sterilized free-roaming cats than those reported previously. More importantly, our results show that sterilization contributes to a considerable reduction in the risk of environmental contamination; TNR therefore appears to be a valuable harm reduction strategy in mitigating the risks of T. gondii infection.

Playgrounds are global environments that are purpose made for children and can offer a variety of opportunities for children to be physically active and practice their fundamental movement skills (FMS), which can lead to future physical activity and sport participation. Previous research highlighted that children engage in different types of physical activity (PA) depending on playgrounds apparatus and area. However, there is a paucity of research that investigates the link between playground features, structures, PA, and FMS. This study sought to assess the impact of different playgrounds on PA type PA intensity and the types of FMS completed. This observational study examined 29 (M = 10, F = 19) children’s behaviours on three different playgrounds. Video cameras were placed strategically across the three playgrounds to allow for footage to be captured and analysed using the Observational System for Recording Physical Activity in Children (OSRAC). One-way ANOVA was used to examine the different OSRAC categories across the three playgrounds. Climbing equipment (average 1217.10 s) was the frequently used type of apparatus, standing was the most commonly performed type of activity (average 377.60 s) and stationary movements whilst moving limbs were the most regularly (average 605.13 s) performed type of PA intensity. There were no instances of any throwing, catching, or kicking activities performed across the three playgrounds. Results suggest that public playgrounds do not facilitate more intense types of PA, nor object control skills due to a lack of suitable equipment. Full article

This study investigates the heavy metal contamination in urban and peri-urban soils of Thessaloniki, Greece, over a two-year period (2023–2024). A total of 208 composite soil samples were systematically collected from 52 sites representing diverse land uses, including high-traffic roadsides, industrial zones, residential neighborhoods, parks, and mixed-use areas, with sampling conducted both after the wet (winter) and dry (summer) seasons. Soil physicochemical properties (pH, electrical conductivity, texture, organic matter, and calcium carbonate content) were analyzed alongside the concentrations of heavy metals such as Cd, Co, Cr, Cu, Mn, Ni, Pb, and Zn. A pollution assessment employed the Geoaccumulation Index (I_geo), Contamination Factor (Cf), Pollution Load Index (PLI), and Potential Ecological Risk Index (RI), revealing variable contamination levels across the city, with certain hotspots exhibiting a considerable to very high ecological risk. Multivariate statistical analyses (PCA and HCA) identified distinct anthropogenic and geogenic sources of heavy metals. Health risk assessments, based on USEPA models, evaluated non-carcinogenic and carcinogenic risks for both adults and children via ingestion and dermal contact pathways. The results indicate that while most sites present low to moderate health risks, specific locations, particularly near major transport and industrial areas, pose elevated risks, especially for children. The findings underscore the need for targeted monitoring and remediation strategies to mitigate the ecological and human health risks associated with urban soil pollution in Thessaloniki.

(1) Background: The provision of monofunctional or inadequately distributed services in urban park green spaces often constrains residents’ opportunities and diversity for outdoor activities, particularly limiting access and participation for specific age groups or activity preferences. However, functional nodes with temporal and spatial flexibility demonstrate high-quality characteristics of resilient and shared services through integrated development. Accurately identifying user demand provides a solid basis for optimizing the functional configuration of urban parks. (2) Methods: This study took the old city area of Zhengzhou, Henan Province, China, as a case study. By collecting and integrating various types of data, such as geographic spatial data, field investigation data, and behavioral observations, we developed a population demand quantification method and a modular analysis approach for park service functions. This framework enabled correlation analysis between diverse user needs and park services. The study further classified and combined park functions into modular units, quantifying their elastic and shared service capabilities—namely, the adaptive flexibility and shared utilization capacity of park services. Additionally, we established a demand-responsive evaluation system for identifying and diagnosing problem areas in park services based on multi-source data. (3) Results: The demand response index and diagnostic results indicate that the supply of fitness facilities—particularly equipment-based installations—is insufficient within the old urban district of Zhengzhou. Among the three user groups—children, young and middle-aged adults, and the elderly—the elderly population exhibited the lowest demand response index, revealing a significant gap in meeting their specific needs. (4) Conclusions: Based on the research findings, a three-tier optimization strategy is proposed: A. improve green space connectivity to expand the service coverage of parks; B. implement multifunctional overlay and coordinated integration in spatial design based on site characteristics and demand diagnostics; and C. increase the total supply of facilities to enhance spatial efficiency in parks. By integrating the demand assessment data and diagnostic results, this approach enabled a data-driven reorganization of service types and targeted allocation of resources within existing park infrastructure, offering a practical tool and reference for the planning of urban outdoor activity spaces.

This study proposes a novel method to assess urban park accessibility by incorporating perceived utility based on both park area and distance. Departing from conventional models that treat accessibility as a function of geometric proximity alone, we define park utility as a distance-discounted benefit of park area, thereby allowing for a more behaviorally grounded measure. A customized discounting function is introduced, where larger park sizes proportionally reduce perceived travel cost, and walking speed adjustments are applied based on demographic user profiles (children, adults, and older adults). The methodology was implemented using a Python-based v.3.12.9 geospatial workflow with network-based distance calculations between 18,614 census block groups and all urban parks in Seoul. Population-weighted utility scores were computed by integrating park size, distance, and age-specific mobility adjustments. The results reveal significant intra-urban disparities, with a citywide deficit of 4,066,046 m in population-weighted distance, particularly in areas with large populations but insufficient proximity to high-utility parks. Simulation analyses of 30 candidate sites demonstrate that strategic park placement can yield substantial utility improvements (maximum gain: 493,436 m), while indiscriminate expansion may not. These findings offer spatial decision support for optimizing limited public resources in urban green infrastructure planning and underscore the need to consider both park scale and user-specific walking behavior in evaluating accessibility.

Background/Objectives: Three distinct language comprehension phenotypes have previously been identified in individuals with language deficits: (1) individuals with the Command Phenotype are limited to understanding simple commands; (2) individuals with the Modifier Phenotype demonstrate additional comprehension of combinations of nouns and adjectives; and (3) individuals with the Syntactic Phenotype possess full syntactic comprehension. We hypothesized that typically developing children progress through these same three language comprehension phenotypes and aimed to determine the typical age at which each phenotype emerges. Methods: To assess comprehension in young children, we developed the 15-item Language Phenotype Assessment (LPA). This tool uses toy-animal manipulatives to avoid reliance on picture interpretation and employs brief instructions to reduce auditory memory load. LPA items incorporate elements such as colors, sizes, numbers, spatial prepositions, and other syntactic components, posing novel combinations of words that children had not previously encountered. The LPA was administered to 116 typically-developing children aged 1.5–7 years, recruited by approaching parents in local parks and inviting them to participate. Results: Findings revealed a developmental trajectory consistent with the three previously described phenotypes: 50% of children attained the Command Phenotype by 1.6 years of age, the Modifier Phenotype by 3.0 years of age, and the Syntactic Phenotype by 3.7 years of age. All children acquired the Command Phenotype by 3, the Modifier Phenotype by 4, and the Syntactic Phenotype by 5 years of age. Conclusions: The LPA is an effective tool for assessing comprehension in children aged 1.5–5 years. It allows for the early identification of comprehension difficulties, supporting the timely initiation of appropriate language interventions. Full article

Challenge, adventure, and risky play have repeatedly been found to be learning environments that positively shape childhood well-being and development. Extant evidence-based research conveys the physical, cognitive, and socio-emotional growth associated with risky play provision. However, understanding the interplay of risky play, injury, and safety is more nuanced and complex. The goal of this paper is to introduce a tool which allows educators, parents, health practitioners, urban planners, playground designers, certifiers, manufacturers, and inspectors to estimate both the benefit and risk of outdoor play and learning settings, such as playgrounds, adventure parks, or risk-taking activities. One of the key challenges associated with societal risk appetite or risk tolerance has been the inability to quantify the inherent benefits of risk taking in playgrounds and educational settings. Historically, the assessment of ‘benefit–risk’ has been dominated by a zero tolerance of incidents, whether in the workplace or road safety settings. Against this backdrop, if playgrounds and outdoor learning settings are boring, children will go elsewhere to seek thrills and adventure, which may often be manifested in antisocial behaviour. In 2023, ‘benefit–risk’ was formally recognised in the area of sport and recreation by the International Organisation for Standardisation, when it published the ISO 4980:2023 benefit–risk assessment for sport and recreational facilities, activities, and equipment. ISO 4980:2023 is a departure from the traditional view of risk management, in that it presents a perspective of risk which is not limited to framing risk as negative, but rather balances the calculation of positive benefits as well as the risks associated with the activity. Correspondingly, hazardous situations which have zero benefit should be eliminated or mitigated. The tool introduced in this paper offers playground inspectors and educators the ability to measure and assess both the benefit and risk of outdoor playgrounds and educational settings where children play, learn, and flourish.
