In the 1600s, more than 200 million acres of wetlands existed in the lower 48 United States, but by the mid-1970s, only 99 million acres remained. Recent estimates show that wetland loss continues at an alarming rate due to mining, dredging and draining, energy and urban development, and a variety of point-source and nonpoint-source toxicants.
Ecologists and toxicologists have only recently begun to determine the impact of these activities and toxic chemicals on wetland ecology, but a basic understanding of these effects on the various trophic levels in wetlands has not yet been achieved. Few workshops or publications have dealt specifically with wetland quality, and fewer still have focused on wetland ecotoxicology and risk assessment. This publication fills those gaps.
