Foreword
A large number of technical grade pesticides
are manufactured in India. Many of these harmful pesticides and
their breakdown products flow out in the wastewater discharged by
pesticide manufacturing and formulation industries. Control of these
toxic compounds is essential to protect aquatic life and to prevent
their entry into the food chain.
The Central Board had earlier prescribed general standards (COINDS/15/85-86)
for discharge of pesticides (including intermediates and metabolites)
in the wastewater from pesticide manufactur- ing and formulation
units. However, it was
considered that the standards should be reviewed and pesticide-specific
standards be evolved as the degree of toxicity varies from one pesticide
to the other. In the present document, standards for specific pesticides
are developed on the basis of available data on their toxicity to
the most sensitive species.
