Pesticides have performed an important function in expanding meals construction, and in view of transforming into all over the world nutrients call for we will anticipate using those chemical compounds to extend. even though, a few of them have came upon their manner into the biosphere and feature been classi­ fied as power poisonous chemical compounds. This has ended in severe predicament approximately environmental infection. in view that we'll proceed utilizing chemical compounds, we should always study extra approximately such elements as their delivery within the setting, the connection in their physical-chemical houses to move, their endurance within the biosphere, their partitioning within the biota, and toxicological and epidemiological forecasting in keeping with physical-chemical houses. Environmental chemodynamics is the identify given to an issue which offers with many of the above issues, using the rules of such disciplines as chemistry, physics, structures research, modelling, engineering, and scientific and organic sciences. to make sure the security of our environment, we needs to recognize extra in regards to the chemodynamical habit of insecticides and similar chemi­ cals. the aim of the symposium "Environmental Dynamics of Pes­ ticides" used to be to discover the concept that of chemodynamics as utilized to insecticides and therefore may also help in constructing the rising box of environmental chemodynamics. The symposium was once held in the course of the l37th nationwide American Chemical Society assembly at la, California, in the course of April, 1974. the 3 classes within the sym­ posium have been chai'red by way of Drs. V.H. Freed, D.G. Crosby, and R. Haque.
