Effects on wildlife

Toxic pollutants in the air, or deposited on soils or surface waters,
can impact wildlife in a number of ways. Like humans, animals can experience health
problems if they are exposed to sufficient concentrations of air toxics over time. Studies
show that air toxics are contributing to birth defects, reproductive failure, and disease in
animals. Persistent toxic air pollutants (those that break down slowly in the
environment) are of particular concern in aquatic ecosystems. These pollutants
accumulate in sediments and may biomagnify in tissues of animals at the top of the food
chain to concentrations many times higher than in the water or air.
