Zhejiang University of Technology, College of Environment,

Dr. Jianqiang Sun is a Professor of Environmental Chemistry and Soil Science at the College of Environment, Zhejiang University of Technology, China, where he obtained his PhD degree in 2012 (Supervised by Prof. Weiping Liu) and has been Associate Professor in 2014 and Professor since 2019. During his postdoctoral training (2014-2015), he started the research on plant metabolism at the University of California, Riverside (Cooperation with Prof. Jay Gan). Currently, his main research area includes environmental fate, behavior, and ecological effect of organic pollution in the agricultural ecosystem, with special interests focusing on the plant uptake and metabolism of emerging contaminants in the soil-plant system. Moreover, he offered a national first-class course “Environmental Protection and Eco-civilization” for open online scientific education.

Dr. Wei (Vivienne) Wang is an associated professor at the Institute of Nuclear-Agricultural Science, Zhejiang University, China. She obtained her PhD degree through join-training at Zhejiang University, China, and the University of California, Riverside. Her research interests and activities mainly focus on the use of isotopic tracing techniques in environmental science, including 1) environmental fate and risk assessment of organic contaminants, i.e., pesticides, PBDEs, antibiotics; 2) processes of organic contaminants in an ecosystem; 3) biotic and abiotic degradation/metabolism, adsorption, leaching, and bound residue formation. She serves as an editor for Science of the Total Environment, Journal of Nuclear Agricultural Science, and Isotope (in Chinese). She has published more than 60 peer-reviewed scientific papers, and her publications have been cited more than 1000 times. Her research contributes to the development of environment-friendly pesticides (i.e., helping cycloxaprid, benzene kresoxim-methyl, and pyribambenz-propyl to obtain their official registration in China), and also contributes to the reduction and remediation of organic pollutants in agricultural fields.

Collection Overview

The extensive production and use of various chemical products have led to the widespread occurrence of organic pollutants (such as pesticides, PPCPs, flame retardants, and plasticizers) in the environment. As an important component of the environment, plants can absorb and accumulate pollutants and convert them into various unknown metabolites, which may pose potential risks to the ecological environment and human health. Plant metabolism of organic contaminants is generating global concern, and a key methodological step in the study of plant metabolism is the identification of biotransformation products. At present, a variety of reliable methods and technologies have been employed to accurately identify metabolites of organic pollutants in plants. For example, the exposure of model plants coupled with high-resolution mass spectrometry (HRMS) has been proven to be an outstanding method to perform sensitive analysis of metabolites. Examples of methods to be included in this collection are: invitro or invivo exposure experiments, radioactive or stable isotope labeling technology, analysis of HRMS data, and insilico prediction method, etc. This methods collection will share standardized protocols for the study of plant metabolism of organic pollutants, providing insights and assistance for pollution control and environmental sustainability.
