Enantioselectivity in Environmental Process and Toxicology of Chiral Contaminants

讲座摘要/Abstract:

The speed at which new chemicals are introduced into the market is accelerating due to the rapid urbanization and industrialization worldwide. Many organic pollutants have structural diversity, such as congener, isomer and especial enantiomers. The significance of molecular chirality is widely recognized in life sciences. Enantiomers of the same compound have identical physical-chemical properties and thus appear as a single compound in standard analysis. For economic reasons, chiral pesticides are primarily used as mixtures of enantiomers, or racemates. However, enantiomers are known to selectively interact with biological systems that are usually enantioselective and may behave as drastically different compounds. Many of organic chemicals are agricultural chemicals, including but not limited to synthetic pyrethroids, organophosphates, acylanilides, phenoxypropanoic acid and imidazolinones. They are typically used in their racemic form. Unfortunately, they exhibit enantioselective behavior during agricultural use. Therefore, these compounds may pose enantioselective ecological threats to non-target organisms and/or humans, affecting the safety of food chain and even the entire ecosystem. Therefore, the toxicity of chiral pollutants has gained much attention in the academia in the recent years. Thus, it is necessary to investigate the relationships between enantioselective environmental process and toxicology of the aforementioned chiral compounds during environmental risk assessment, which has been the main focus of my research group in the past 20 years.
