Question

Chemiced pesticides.
are not udvisable for use​

Answer 1

Answer:

By their nature, pesticides are potentially toxic to other organisms, including humans, and need to be used safely and disposed of properly. They are among the leading causes of death by self-poisoning, and this burden is felt disproportionately in low- and middle-income countries.

Many of the older, cheaper (off-patent) pesticides, such as dichlorodiphenyltrichloroethane (DDT) and lindane, can remain for years in soil and water. These have adverse effects on larger parts of the ecosystem and can accumulate in the food chain. These chemicals have been banned by countries who signed the 2001 Stockholm Convention.
