AC 604 AGROCHEMICAL DYNAMICS AND ENVIRONMENTAL IMPLICATIONS                   (3L+1P) III

Objective
  To acquaint students with fate of pesticides in environment-their movement in plants and food chain, persistence, transformation and other metabolic fates.

Theory

UNIT I
  Biotic and abiotic transformations of agrochemicals in the environment.

UNIT II
  Soil: sources of contamination, microbial transformation, adsorption-desorption, leaching/mobility, volatilization.

UNIT III
  Aquatic bodies: sources of contamination, transformation processes, bioaccumulation etc.

UNIT IV
  Air: sources of contamination, transformation and transport processes.

UNIT V
  Soil –plant –animal system: uptake, translocation, metabolism, degradation.

UNIT VI
  Adverse effects of pesticides on micro-flora, fauna and on other non-target organisms.

Practicals
  Preparation of metabolites, photodegradatin of pesticides, leaching and volatilization of pesticides, biological degradation in soil.
