Special Issue Information

Dear Colleagues,

Persistent organic compounds (POPs) are anthropogenic chemicals that are characterized by persistence, bioaccumulation, long-range transportability and toxicity. Based on these properties and public concern, the production and use of POPs have been restricted under the Stockholm Convention since 2001. Understanding the fate, bioaccumulation and risk assessment of POPs is one of the principal approaches to evaluate their environmental distribution, transport and potential toxic impact. Importantly, bioaccumulation of POPs can lead to biomagnification, resulting in a higher accumulation level in the organisms at the top of the food chain. Considering the ubiquitous distribution and alarming potential health impact of POPs, on-going scientific research on the fate, bioaccumulation and risk assessment of POPs is necessary. In addition, experimental results from this line of study will provide a basis for the rational implantation of regulative measures.

This Special Issue aims to contribute to the scientific community by broadening the research area of fate, bioaccumulation and risk assessment of POPs. To this end, we invite you to submit your research (original research articles and reviews) addressing any aspects of this field of study. We particularly welcome contributions that consider the following topics:

1) Distribution, transport and fate of POPs in various environmental matrices (e.g., atmosphere, freshwater);
2) Bioaccumulation of POPs in biota, including lab animals, wildlife and humans;
3) Exposure and risk assessment of POPs with (novel) scientific approaches.

We look forward to receiving your contributions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Toxics is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Background: The aim of the study was to review data on the impact of anthropogenic chemicals (endocrine disruptors) on various diseases, which, consequently, may facilitate their prevention and be used as a tool for managing public healthcare. Every day, humans are exposed to chemicals, including xenoestrogens, which are similar to female hormones. Methods: This manuscript was prepared based on a meta-analysis of research on the impacts of selected EDCs on human health. Results: Special attention should be paid to bisphenol A (BPA), benzo-α-pyrene, and phthalates due to their proven endocrine activity and presence in our daily lives. Xenoestrogens are absorbed by human organisms through the digestive system since they can migrate to food from food packages and drinks as well as from plastic products used daily. The presence of these chemicals in human organisms is considered a potential cause for some diseases commonly referred to as ‘diseases of civilization’. Conclusions: The biomonitoring of xenoestrogens, which are chemicals with unfavorable impacts on human health, is a crucial tool for assessing the risk from the pollution of the environment. The novelty is a holistic approach to assessing the occurrence of risk factors for civilization diseases. Full article

Tissue-Specific Distribution of Legacy and Emerging Organophosphorus Flame Retardants and Plasticizers in Frogs

Five types of tissues, including the liver, kidney, intestine, lung, and heart, were collected from black-spotted frogs and bullfrogs to study the tissue-specific accumulation of organophosphorus flame retardants (PFRs) and plasticizers. Thirteen PFRs and nine plasticizers were detected, with average total concentrations of 1.4–13 ng/g ww and 858–5503 ng/g ww in black-spotted frogs, 3.6–46 ng/g ww and 355–3504 ng/g ww in bullfrogs. Significant differences in pollutant concentrations among different tissues in the two frog species were found, indicating the specific selectivity distribution of PFRs and plasticizers. Overall, liver tissues exhibited significantly higher pollutant concentrations. The pollutant concentration ratios of other tissue to the sum of liver tissue and other tissues (OLR, Cother/(Cother + Cliver)) corresponding to male frogs were significantly greater than those of females, suggesting that male frogs could have higher metabolic potentials for PFRs and plasticizers. No obvious correlations between OLR and log KOW were found, indicating that the other factors (e.g., bioaccumulation pathway and metabolism) besides lipophicity could influence the deposition of PFRs and plasticizers in frog livers. Different parental transfer patterns for PFRs and plasticizers were observed in frogs when using different tissues as parental tissues. Moreover, the liver tissues had similar parental transfer mechanism with muscle tissues. Full article
