Foreword
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. The present report deals with 20 major pesticides manufactured in the country. Other pesticides will be covered in due course.

It is hoped that the report will be useful to industries, regulatory agencies and all other interested in the control of pollution from pesticide industries
