Pesticides, where used correctly, can save up to 40% in crop losses ; however, when pesticides are mal-mis-or over-used the environmental and public health consequences can be very considerable.
The United Nations has issued a list of chemicals that are banned or severely restricted in use ; many of the chemicals on this list are pesticides.
Whilst the use of highly persistent pesticides such as DDT has proved very effective in the eradication of diseases such as malaria, the adverse effects to the natural environment have been devastating - whole populations of birds have been eliminated.
Within the former Soviet Union, the use of highly persistent pesticides was widespread ; this has resulted in contamination of both crops, with pesticide residues well in excess of internationally acceptable maximum residue limits, and water resources to such high level that remediation through natural processes will take decades, or by xenobiotic or physicochemical processes will be extremely costly.
This is an extraordinary situation as the former Soviet Union had one of the most stringent of environmental regulation - the GOST regulations ; unfortunately these were not pragmatic and rarely applied.
