An early life stage (ELS) test is a chronic toxicity test using sensitive early life stages like embryos or larvae to predict the effects of toxicants on organisms. ELS tests were developed to be quicker and more cost-efficient than full life-cycle tests, taking on average 1–5 months to complete compared to 6–12 months for a life-cycle test. They are commonly used in aquatic toxicology, particularly with fish. Growth and survival are the typically measured endpoints, for which a Maxi… Web• OECD 210: Fish, Early-life Stage Toxicity Test • OECD 211: Daphnia magna Reproduction Test The following guidelines, directly relevant for REACH registration … dwayne allen pawcatuck
