| Shrnutí: | An understanding of the effect of pesticides is
essential for rational decision-taking regarding their
authorization. The retention of a pesticide by soil can
prevent its short-term access to ground or surface waters
and its effects on non target organisms, but the persistence of
the under graded pesticide or of harmful metabolites
constitutes an ever present – and cumulative – risk to the
environment and, eventually, to human health. The soil
mineralogy, chemical decomposition and atmospheric
conditions highly influence the pesticide retention and
release of it and consequently the degradation of the
compound. The analysis conducted on water samples across
the entire district shows that the water sources are protected
from contamination by any pesticides.
However, the
indiscriminate use of pesticides in Cardamom plantations
will be a threat to the Indian Cardamom Hills, the Idukki
District since the persistent pesticide residue of endosulfan,
DDT and organophosphorous toxic chemicals are present in
high concentration. The soil mineralogy of Idukki is
favorable to its persistence and hence strict control and
awareness to farmers for judicious use of pesticides is
necessary to avoid pollution of water sources and
contamination of the soil. |
