Factors affecting water strider (Hemiptera: Gerridae) mercury concentrations in lotic systems [PDF]

Environmental Toxicology and Chemistry, 2009
Abstract Water striders (Hemiptera: Gerridae) have been considered as a potential sentinel for mercury (Hg) contamination of freshwater ecosystems, yet little is known about factors that control Hg concentrations in this invertebrate. Striders were collected from 80 streams and rivers in New Brunswick, Canada, in August and September of ...
