Description of key information

The acute toxicity of 7PPD to the freshwater fish, Lepomis macrochirus was investigated in a static test according to EPA-600/3-75-009. After 96 hours of exposure an LC50 of 0.3 mg/L (nominal) was determined. In addition to the Key Study, two additional acute toxicity sutdies used as Supporting Studies, were conducted with 7ppd exposed to rainbow trout (Oncorhynchus mykiss, formerly known as Salmo gairdneri). The resulting 96 -hr LC50 values were 0.4 and 0.42 mg/L (nominal).
