Chemical Toxicity Endpoint Type Endpoint Description Endpoint Value Sample Size Life Cycle Stage Study Duration Type
FENTHION TOX-Non-Repro-Sublethal - whole animal temperature tolerance, estimated by heating water at 1C/3min and using onset of spasms in frogs as the endpoint decrease @ 60 ppb 10 animals/replicate; 2 replicates/dose Juvenile 24 hr Toxicity Factor Datasets
CHLORPYRIFOS TOX-Non-Repro-Sublethal - whole animal temperature tolerance, estimated by heating water at 1C/3min and using onset of spasms in frogs as the endpoint decrease @ 30 and 60 ppb 10 animals/replicate; 2 replicates/dose Juvenile 24 hr Toxicity Factor Datasets
METHYLPARATHION TOX-Non-Repro-Sublethal - whole animal temperature tolerance, estimated by heating water at 1C/3min and using onset of spasms in frogs as the endpoint decrease @ 25 and 50 ppb 10 animals/replicate; 2 replicates/dose Juvenile 24 hr Toxicity Factor Datasets
