–Eating contaminated food products, such as fish from contaminated waters; meat, milk, or eggs from animals
that feed on contaminated plants;
and fruits and vegetables grown in contaminated
soil on which air toxics have been deposited.
–Drinking water contaminated by toxic air pollutants.
–Ingesting contaminated soil.
–Touching contaminated soil, dust, or water.
–Accumulating some persistent toxic air pollutants in body tissues after toxic air pollutants have entered the body.
Predators typically accumulate
even greater pollutant concentrations than their contaminated prey. As a result, people and other
animals at the top of the food
chain who eat contaminated fish or meat are exposed to concentrations that are much higher than the concentrations in the water, air, or soil.
