Special Issue Information

Dear Colleagues,

Emerging pollutants—including pharmaceuticals, personal care products, pesticides, microplastics, and industrial chemicals—pose increasing risks to environmental and human health due to their persistence, bioaccumulation potential, and limited regulation. The development of sustainable, effective, and ecologically sound strategies for the detection and mitigation of these contaminants has become a global research priority.

This Special Issue aims to bring together recent advances in biomonitoring and bioremediation technologies applied to emerging pollutants in diverse environmental matrices (soil, water, air, and sediment). It welcomes contributions that explore novel bioindicators, biosensors, molecular tools, and omics-based approaches for pollutant detection and risk assessment. Equally, we seek innovative studies on microbial, plant-based, or combined biological remediation systems, with an emphasis on mechanisms, process optimization, and field applications.

Topics of interest include (but are not limited to) the following:

  • Development and application of biomonitoring tools for emerging contaminants;
  • Biosensors and bioassays for pollutant detection;
  • Microbial and phytoremediation of emerging pollutants;
  • Bioaugmentation and biostimulation strategies;
  • Enzymatic degradation and metabolic pathways;
  • Synergistic processes involving biotic and abiotic remediation;
  • Risk assessment and environmental modeling using biological indicators;
  • Case studies and pilot-scale applications of bioremediation technologies;
  • Bioreactor systems and process engineering for pollutant removal.

Original research articles, comprehensive reviews, and case studies are all welcome. Contributions should highlight scientific innovation, interdisciplinary approaches, and the potential for environmental impact and sustainability.

Thank you, and I hope you consider participating in this Special Issue.

The disinfection process in wastewater treatment is key to the discharge and/or reuse of high-quality effluent. However, disinfection using ultraviolet (UV) light may be inefficient because bacteria possess mechanisms for repairing damaged DNA. This study aimed to assess the photoreactivation and dark repair of total coliform (TC) in wastewater effluent after UV-C disinfection treatment. Four UV-C doses (28.8, 53.1, 57.6, and 106.2 mJ/cm2) and two post-irradiation conditions (light vs. darkness) were applied. Reactivation was monitored after 2, 4, 6 and 24 h (25 °C). Similar TC inactivation efficiencies were observed for the three lowest UV-C doses, whereas the 106.2 mJ/cm2 dose achieved the greatest reduction (1.1 Log of TC), decreasing TC concentrations from 3.1 × 105 ± 3.5 × 105 to 1.2 × 105 ± 1.4 × 105 MPN/100 mL. Reactivation assays revealed substantial bacterial recovery after UV treatment, with 24 h survival rates up to 2.3 × 103 under light and 9.2 × 102 in darkness. Photoreactivation and dark repair assays revealed substantial variability in bacterial recovery after UV treatment depending on UV-C dose, post-irradiation condition and incubation time. In general, bacterial recovery was still detected even at the 106.2 mJ/cm2 dose, particularly after 24 h of incubation (178–604%). These findings suggest that effective organic matter removal before UV-C disinfection is critical to improve UV transmittance, reduce shielding effects, and limit subsequent bacterial recovery.

While mining is a highly important economic activity, it generates considerable environmental impact, especially during the grinding and extraction stages of metallic minerals, leading to the formation of waste known as mine tailings. These mine tailings, often abandoned in various regions of Mexico due to a lack of prior environmental regulations, contain heavy metals that pose a risk to both the environment and human health. In Huautla, Morelos, where metals such as silver (Ag), gold (Au), copper (Cu), lead (Pb), and zinc (Zn) were extracted from the 16th century until 1988, it is estimated that there are approximately 780,000 tons of mine tailings. These mine tailings are contaminated with heavy metals such as cadmium (Cd), Cu, chromium (Cr), manganese (Mn), Pb, and Zn, and the bioaccumulation and biomagnification of these metals have been documented in various plant and animal species in the region, indicating their bioavailability. The study conducted in this area consisted of determining the concentration of Cd, Cu, Cr, Mn, Pb, and Zn, as well as the sequential extraction of mine tailings 1 and 2 to identify metal bioavailability. The results showed for both mine tailings, that the metals with the highest concentrations were Pb (mine tailing 1: 1666 ± 317.7 mg/kg, mine tailing 2: 1329 ± 30.8 mg/kg) and Zn (mine tailing 1: 1327 ± 314.9 mg/kg, mine tailing 2: 1099 ± 34.3 mg/kg), found in fractions IV and VI, respectively. In mine tailings 1, the main bioavailable metals were Cd (75.3%), Mn (53%), Pb (39.8%), and Cu (36.4%), while in mine tailings 2, the bioavailable metals were Cd (56.8%), Pb (37.9%), and Cu (29.3%). In general, Cd and Pb exhibited the highest bioavailability in both mine tailings. According to the calculated risk indices, bioavailable Cd and Pb pose the highest pollution, ecological, and non-carcinogenic risk in both mine tailings, while bioavailable Cr showed the highest determined carcinogenic risk. This study demonstrated that the mining waste from Huautla contains high levels of bioavailable heavy metals, posing ecological and public health risks, and provides valuable information for the development of effective environmental remediation strategies.
