how can chemical weedicides cause pollution
Answers
Answer:
Herbicides are frequently used in the chemical control of weeds in various crops in Brazil and worldwide, so they are more frequently detected outside the application areas, contributing to the risk of environmental contamination. The importance of knowledge of the physicochemical properties of the environment and the pesticide used in the agricultural area is in order to understand its effects on terrestrial and aquatic ecosystems and the search for the prevention of future bioaccumulation potentials (bioconcentration and/or biomagnification) of molecules of pesticides in living nontarget organisms, minimizing their negative effects on the environment. The understanding of analytical techniques for measuring the quality of water resources as well as techniques for the remediation of contaminated water is essential to minimize the possible impacts caused by the application of pesticides to the environment.

Weedicides will affect local biodiversity: greens. Spraying weedicides to control undergrowth in vacant plots will wipe out local plant and animal biodiversity, conservationists have warned. ... The removal of such plants would affect the large number of butterfly and dragonfly species too, he said.｡◕‿◕｡
