As one of the earliest safety assessment institutions in China, we have more than 50 years' experience in toxicology research. We have gradually developed from a toxicology group to a large safety assessment center with several GLP qualifications at internal and abroad. Health toxicology study covering acute toxicity, repeate toxicity, genetic toxicity, reproductive toxicity, microbial pesticide pathogenicity，metabolic kinetics and carcinogenesis could be carry out in accordance with OECD GLP and ICAMA GLP. Data and reports of health toxicology study for various pesticides have used and registered in China, the Netherlands, Mexico, the United States, and the United States. Singapore, Argentina, Brazil, India, Japan, Korea, Pakistan, Taiwan and other countries. In addition, we can also carry out field exposure test for pesticides, and provide risk assessment data and one-stop registration service.
