UNIT 5 - Transport and fate of contaminants in the environment

The discussion that follows is a general overview of the fate, transport and transformation of contaminants in the environment. To better understand the transfer of chemicals in the environment, some important concepts (e.g.: environmental persistence, bioaccumulation, biomagnification) are explained. Finally, an introduction on environmental fate models is presented.

This chapter is divided into six sections:

1. Introduction

2. Transport processes

3. Environmental persistence and transformation processes

                3.1 Abiotic degradation

                3.2 Biotic degradation

                3.3 Nondegradative elimination processes

4. Bioaccumulation

                4.1 Factors that influence bioaccumulation

5. Environmental fate models

6. Brief conclusion
