摘要：Increasing effort has been placed recently on detecting, characterizing, and predicting the environmental fate and effects of chemicals of emerging concern (CECs), given the potential toxicity of these chemicals to humans and aquatic ecosystems. In particular, there is great interest in reducing the environmental burden of polar CECs, such as pharmaceuticals and personal care products, modern agrochemicals, and their various metabolites and degradates. However, significant knowledge gaps remain, given limitations in sampling and quantification technology. Our research group has pioneered the development and evaluation of novel aquatic passive samplers, such as the organic diffusive gradients in thin films device (o-DGT) for continuous measurement of polar CECs, to delineate processes and factors affecting their performance and understanding their limitations. Quantitative means to eliminate the many interferences in wastewaters to measure Phase II CEC metabolites (e.g., glucuronide and sulfate conjugates) by liquid-chromatography tandem mass spectrometry has revealed concentrations of these chemicals in treated wastewaters and receiving waters rivaling or exceeding that of parent compounds. Use of these technologies has demonstrated significant riverine transport of polar CECs across national boundaries, modulated by the physical-chemical properties of the CECs and their land use patterns, demonstrating that an integrated approach is necessary for mitigation of such contaminants.
简介：Dr. Charles Wong is the Canada Research Chair in Ecotoxicology at the University of Winnipeg. His research interests are in the measurement, fate, and effects of organic contaminants in aquatic and terrestrial ecosystems. Dr. Wong holds SB and SM degrees from MIT and a PhD from the University of Minnesota, all in civil and environmental engineering. He has 95 peer-reviewed publications to date, and currently holds concurrent appointments by invitation around the world: Jinan University Chair Professor (China), the Instituto Tecnológico de Costa Rica, the Children’s Hospital Research Institute of Manitoba, and the University of Manitoba. He recently completed a term of service on the Board of Directors of the Society of Environmental Toxicology and Chemistry, and is Associate Editor of the international journalEnvironmental Pollution. Dr. Wong is also a nationally-ranked archer who has been invited to compete at the World Championships.
