Effects of Chlorpyrifos on Field- and Laboratory-Developed Estuarine Benthic Communities

摘要

Macrobenthic animal communities, developed in sand-filled aquaria in the laboratory and in the field, were exposed to various concentrations of the insecticide, chlorpyrifos, and effects on community structure assessed. Laboratory communities were continuously exposed to the toxicant for eight weeks during colonization by planktonic larvae in unfiltered Santa Rosa Sound, FL, seawater. Field communities developed for eight weeks in aquaria placed in Santa Rosa Sound and then removed to the laboratory for exposure to chlorpyrifos for one week.
