Institute of Pesticide and Environmental Toxicology (IPET) was built in 1953.. Imbursed by Ministry of Science and Technology, Ministry of Agriculture, and so on, IPET involved in ecochemical and ecotoxicological researchs, in its field research stations, of several key pesticides, such as HCH, carbofuran, methamidophos, and so on, which was applied in rice field since from 1980s to 1990s.. These researches settled scientific foundation for evaluation of hazard being imposed on human and ecosystem by pesticides. While IPET earned its reputation by performing these scientific activities. Scientists in IPET put forward the concept of “Pesticide Ecotoxicology” firstly in China in 1980s, based on tremendous data on behavior and side-effects of pesticides collected from lab, semi-field, and field.

     Recently obvious progress has achieved in many aspects, such as, residual pollution control, ecotoxicology, computer expert system, instant residue detection (ELISA), biological pesticide and “green” formulation exploitation. New characters and predominance are coming into being.
Main research directions include 1) Pesticide synthesize and structure decoration, 2) Pesticide formulation, 3) Pesticide bioassay, 4) Ecotoxicology of pesticide (environmental behavior and side effect of pesticide on non-target organisms, ecological risk assessment and methodologies for instant detection of pesticide residue, e.g., ELISA, and so on), 4) Pesticide pollution control.
Researches on pesticide formulation and processing began in 1987. Hundreds of recipes and processing has been brought forth since then. Nearly 30 of them were put into production. Good cooperation thus developed between IPET and pesticide manufactures from both home and abroad. Environmental friendly preparations being brought forth by now include emulsion in water (EW), micro emulsions (ME), suspension concentrates (SC), suspension emulsions (SE), water dispersible granules (WDG), water dispersible tablets (WDT), soluble powder (SP), soluble tablets (ST), aqueous solutions (AS), and so on. Since 2000, IPET taken on scientific programs, such as “Research and development of aqueous preparation of pesticides”, “Application of environmental friendly adjuvants in pesticide preparation”, which were imbursed by national Ministry of Science and Technology. Research capacity on this aspect are among advanced plane within the country.

    IPET consists of 23 staffs, including 2 professors, 4 associate professors, 1 postdoctoral scientist, 3 lectures, 1 engineer, and 12 technicians. In addition IPET retains 2 guest professors (one of them is academician of Chinese Academy of Science) and 2 part-time professors,
IPET has the most integrated professional labs with total area of 2500 m2, including: 1) Lab of Pesticide Synthesization, 2) Lab of Pesticide Processing, 3) Lab of Pesticide bioassays, 4) Lab of Pesticide Environmental Toxicology, 5) Lab of Pesticide Pollution Ecochemistry, .
The lab of pesticide formulation is equipped with many types of experimental formulation processing machines, including: high shear mulser, mill, rotary screw extruding pelleter, double-screw extruding pelleter, mini-type pneumatic jet mill, high speed machine mill, Shaking mix implement, Magnetic Stirrers, pH meter, Balances, Ultrasonic Cleaners, Forced Convection Constant Temperature Ovens, Bowl-type Constant Temperature Ovens, Vacuum Drying Ovens, tabletting machine, and so on.

    Various middle scale test machines, such as high sheer mulser, high pressure homogenizer, blender, horizontal mill, and so on, are also equipped in a multi-function middle scale test lab which could be used for production techniques research. These machines can be applied for production of .aqueous preparations, such as EW, ME, SE, SC, AS, and so on, and other liquid preparation, such as EC, ULV, OF, OL, and so on.

    The room of analysis has equipped with HPLC, GC, laser particle size analyzer, Zeta potentiometer, surface tensiomete, liquid-moisture measurement instrument, kinematic viscosity, conductivity meter, lap centrifuges, solid-moisture measurement instrument, and so on.
The Bioassay Lab of Pesticide sets up professional insects breed room, weed test room and germfree room, and equipped with several sets of artificial climate box and two sets of automatic spray simulative equipment, which could fulfill indoor virulence test requirements and could also be used for pesticide mixed CTC test and selection test of new compound for pesticide.

    As the sole authorized collegiate lab plenty of experiments in terms of pesticide residue analysis, pesticide quality inspection, and pesticide ecotoxicity are intrusted by Ministry of Agriculture and by pesticide companies from home and abroad. Result of the experiments lays scientific foundation for pesticide registration and for establishment of standard for environmental safety assessment.
   
    Many research programs being conducted nowadays IPET are financially supported by National Natural Science Foundation of China (3 projects), “973”(1sub-project) Plan, National Doctoral Science Foundation (1 project), National Key-Problem Tacking Projects in the 10th Five-Year Plan (1 project), and Ministry or Provincial Foundation (9 projects). In addition to that there exist 2 large-scaled projects sponsored by industrial companies. More than 70 articles have been published. Research fruits included a first class Provincial Award for Scientific and Technical Progress of 2003, a second class National Award for Scientific and Technical Progress of 2005, 2 National Invention Patents and 2 National Practical Patents.

    IPET took the leading in recruiting M. D. candidates majoring in pesticide environmental toxicology at 1981 and Ph. D. candidates majoring in pesticide ecotoxicology at 1991 from home and abroad in the country. By now, more than 100 M. D. students and Ph. D. students have graduated from the institute. They were employed in state universities, state research institutes, national and provincial organs, and foreign invested enterprises. More than 40 students are now studying in the institute.

    IPET urge to cooperate with scientists and organizations both from home and abroad!
