ABSTRACT
When present at a sufficiently high concentration, a pollutant can elicit adverse effects on the living processes of an organism. To exert damage to an exposed organism, a pollutant must first enter the host and reach its target site. A complex pathway exists between the time of initial toxicant exposure and the manifestation of damage by the organism. This chapter discusses general ways in which environmental pollutants exert their actions on plants, animals, and humans.
