Cholinesterase (ChE) response and related mortality among birds fed ChE inhibitors
Patterns of mortality and inhibition of brain and plasma ChE in birds treated with ChE inhibitors were studied in an attempt to determine the validity of using ChE activity as a monitoring andExpand

Some Endrin Relationships in Resistant and Susceptible Populations of Golden Shiners, Notemigonus Crysoleucas
Abstract A 1000 ppb endrin solution killed 50 susceptible golden shiners in 75 min but only 40 of 50 resistant shiners in 40 hr. Endrin residues in whole bodies of resistant shiners killed in endrinExpand

Mixed function oxidase activity in freshwater fishes: aldrin epoxidation and parathion activation.
Abstract Experiments are described which demonstrate that freshwater fishes possess mixed function oxidase (MFO) enzymes which catalyze the epoxidation of aldrin and the activation of parathion inExpand

Effect of sesamex on brain acetylcholinesterase inhibition by parathion in fishes
ConclusionsOur experiments indicate that the degree of brain AChE inhibition resulting from exposure to parathion is decreased by pretreatment with sesamex. Presumably the decrease is mediated — asExpand

Dynamics of Endrin Uptake and Release by Resistant and Susceptible Strains of Mosquitofish
Abstract Results of bioassays and gas chromatographic analyses show that mosquitofish, Gambusia affinis, from near heavily-treated cotton fields near Belzoni, Mississippi (36-hr TLm = 1,000 ppb) andExpand
