This book focuses on exposure toxicology in C. elegans. The nematode Caenorhabditis elegans is sensitive to various environmental toxicants and stresses, and has proven to be an important animal model in both molecular and target-organ toxicology. As a result, over the past 30 years, there has been extensive research on the exposure to environmental toxicants or stresses in nematodes. Based on the available data, the book offers an introduction to the exposure system established in nematodes, discussing various aspects of endpoints that can potentially be used to assess the toxicity of environmental toxicants or stresses. Also exploring various factors affecting toxicity induction, and exposure to environmental toxicants and stresses, it allows readers to gain a systematic understanding of exposure toxicology in C. elegans. 

Dr. Dayong Wang is a Professor at the Medical School, Southeast University, China. He obtained his Ph.D. from Peking University in 2001 and completed his postdoctoral training at the University of Toronto from 2002 to 2004. His research focuses on toxicology and pathology using Caenorhabditis elegans as a model animal, fields in which he has published more than 160 research articles.
