Special Issue Information

Dear Colleagues,

The World Health Organization defines endocrine-disrupting chemicals (EDCs) as “exogenous substances or mixtures that alter function(s) of the endocrine system and consequently cause adverse health effects in an intact organism, or its progeny, or (sub) populations”. EDCs are a highly heterogeneous group of natural and synthesized chemicals, which are ubiquitous in the environment. Human exposure to them occurs through different ways, such as inhalation, ingestion of contaminated food and/or water, and dermal contact by the use of personal care products.

EDCs can alter the functions of different natural hormones; they can act directly on hormone receptors as agonists or as antagonists or indirectly interfering with synthesis, transport, metabolism, and excretion of hormones. Exposure to low doses of EDCs is enough to induce effects, and the exposure during specific life time periods can induce permanent adverse effects.

Traditional assessment of EDCs, based on identifying and quantifying individual chemicals, has some limitations: it is performed considering specific known substances and cannot quantify the effect of unknown or unconsidered compounds, and the cumulative effects of a mixture cannot be directly concluded from individual EDC levels as synergistic/antagonistic interactions are not considered. In addition to the chemical assessment, biological monitoring represents a key element. It is performed through effect-based tools which are able to evaluate the total effect induced by numerous, bioavailable chemicals with the same mechanism of action. In particular, the estrogenic activity of environmental or biological samples has been proposed and utilized as an EDC exposure biomarker.

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. International Journal of Environmental Research and Public Health is an international peer-reviewed open access semimonthly journal published by MDPI.

Cross-Sectional and Longitudinal Effects of PCB Exposure on Human Stress Hormones in the German HELPcB Surveillance Program

Multiple pathological associations are attributed to PCBs (polychlorinated biphenyls). Research shows a positive association of PCBs with dehydroepiandrosterone sulfate (DHEAS) concentration but the results on the stress hormone cortisol have been inconsistent so far. This study is the first to examine not only the cross-sectional but also the longitudinal effects of PCB exposure on the stress hormones DHEAS and cortisol. Over a period of three years, 112 former employees occupationally exposed to PCBs were tested for their body burden with different types of PCBs (lower and higher chlorinated, dioxin-like and hydroxylated) and for their stress hormone concentration. Highly exposed employees showed a significantly higher risk for higher DHEAS values. Multiple linear regression analysis revealed a positive relationship between the exposure to lower chlorinated PCBs and DHEAS. Mixed models also revealed a significantly positive correlation between lower chlorinated PCBs with DHEAS when controlled for a cross-section. However, an effect for cortisol was not found. These results suggest a causal pathophysiological relationship between PCB exposure and DHEAS concentration, but not with cortisol. The health consequences of high DHEAS concentrations are discussed.
