Schimmel, S., Richard L. Garnas, J. Patrick, Jr., AND J. Moore. ACUTE TOXICITY, BIOCONCENTRATION, AND PERSISTENCE OF AC 222,705, BENTHIOCARB, CHLORPYRIFOS, FENVALERATE, METHYL PARATHION, AND PERMETHRIN IN THE ESTUARINE ENVIRONMENT. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/J-82/030 (NTIS PB83191239).
Description:
Six pesticides were evaluated in laboratory studies to determine: acute (96-h) toxicity, octanol/water partition coefficients (Log P), solubility, and persistence in seawater. In addition, three of the six pesticides (synthetic pyrethroids) were tested using the eastern oyster (Crassostrea virginica) in long-term (28 days) tests to determine their respective bioconcentration factors (BCF). Acute toxicity tests provided the following decreasing order of toxicity to estuarine crustaceans and fishes: AC 222,705; fenvalerate, permethrin chlorpyrifos, methyl parathion, and benthiocarb.
