This OCSPP 850.1075: Freshwater and Saltwater Fish Test is intended to determine the acute toxicity of chemical substances and mixtures in aqueous conditions. In this method, freshwater and saltwater fish are exposed to the test material in order to asses the hazards and risks of the material in an aquatic environment. This acute toxicity test […]

EPA – OCSPP 850.1075: Freshwater and Saltwater Fish Acute Toxicity Test

OECD 203 is an acute toxicity test that evaluates the toxicity of a test substance to different fish species. Standard testing for OECD 203 exposes fish to a test substance for a period of 96 hours. Mortalities are recorded at 24, 48, 72, and 96 hours, and the concentrations that kill 50% of the fish are determined when possible. At least five […]

OECD 203: Fish, Acute Toxicity Test

OECD 210 is a toxicity test against fish in their early life stage. OECD 210 exposes fish in their early life stage to a range of concentrations of the test chemical dissolved in water. Tests done on early-life stages of fish are intended to define the lethal and sub-lethal effects of chemicals on the stages and […]

OECD 210: Fish, Early-life Stage Toxicity Test

OECD 212 is a short term toxicity test performed on Fish Embryo and Sac-fry Stages. In the OECD 212 standard test, different life stages from the newly fertilized egg to the end of the sac-fry stage are exposed to the test substance at normally 5 different concretions. OECD 212 is intended to define lethal, and to a […]

OECD 305 is a bioaccumulation test performed with freshwater, estuarine, or marine fish species. The OECD 305 method measures the residues of a test substance in fish after exposure to the test substance in an aqueous environment.  There are three different methods within the OECD 305 methodology: Part I: Aqueous Exposure Bioconcentration Test Part II: Minimized Aqueous Exposure Test Part […]
