Special Issue Information

Dear Colleagues,

In recent years, with the accelerating process of industrialization, the natural environment and social environment are also undergoing drastic changes. The resulting adverse environmental factors have become important risk factors threatening the health of people around the world. Among them, environmental chemical factors (such as per- and polyfluoroalkyl substances, phenols/bisphenols, pesticides, PAHs, brominated flame retardants, organophosphorus flame retardants, etc.) have been proven to be closely related to a variety of adverse human health outcomes due to their extensive exposure in the environment and population. However, studies on the adverse effects of chemicals in the environment and population and their mechanisms are still limited.

This Special Issue aims to address the recent emerging environmental health concerns and to communicate new knowledge from up-to-date research in the exposure sciences and corresponding toxicology for emerging contaminants.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Food pollution, air pollution, marine pollution and human exposure and their health implications;
  • Attention to the chirality (the exposure and toxicity profile) of chiral chemicals;
  • Identifying clues linking environmental chemical exposure as well as occupational chemical exposure (intentional and/or unintentional) to adverse health outcomes.

We look forward to receiving your contributions.

The potential risk posed by the chiral triazole fungicide prothioconazole and its metabolite, prothioconazole-desthio to aquatic ecosystems has attracted attention. At present, the aquatic toxicity of prothioconazole is focused on aquatic animals, and the study of aquatic plants is limited. In this work, the acute toxicity of prothioconazole (PTZ) and its metabolite, prothioconazole-desthio (PTD), to the aquatic plant Lemna minor (L. minor) was evaluated at the enantiomer level. The effects of the prothioconazole and its metabolite enantiomer on the physiological and biochemical indices, including growth rate, photosynthetic pigment content, and antioxidant-defense-enzymes activity, of L. minor were measured to evaluate the potential risk. The results showed that prothioconazole and prothioconazole-desthio possessed obvious stereoselective toxicity to Lemna minor with an LC50 (7 days) of 0.76–5.63 mg/L. The toxicity order was S-PTD > Rac-PTD > S-PTZ > R-PTD > Rac-PTZ > R-PTZ. The S-PTZ, which had the highest toxicity, obviously inhibited the biosynthesis of photosynthetic pigments and the activity of antioxidant-defense enzymes (malondialdehyde, catalase and superoxide dismutase), leading to an increase in MDA content and oxidative damage. The results further confirmed that the metabolism of PTZ in aquatic ecosystems increased its exposure risk, providing data support and a theoretical basis for the risk assessment of PTZ. Full article
