WebThe chronic toxicity of chemicals to fish is routinely assessed by using fish early life stage (ELS) test results. Fish full life cycle (FLC) tests are generally required only when toxicity, bioaccumulation, and persistence triggers are met or when there is a suspicion of potential endocrine-disrupting properties. This regulatory approach is ... WebThe fish early life-stage toxicity test (FELS; OECD TG 210; OECD, 2013a) is the most commonly used test to establish chronic fish toxicity, i.e. to determine lethal and sublethal effects of a chemical on early life stages of fish (embryos, larvae, juvenile fish). The endpoints are hatching success, abnormal appearance, abnormal behaviour ...

WebResults of several studies of the toxicity to early life-stages of different fish species indicate that dispersed microsized TiO2 is not chronically toxic to freshwater fish up to at least 160 mg/L (NOEC ≥ 160 - 1000 mg/L) whereas dispersed nanosized TiO2 is not chronically toxic up to 80 mg/L (NOEC ≥ 80 - < 1000 mg/L). WebTests done on early-life stages of fish are intended to define the lethal and sub-lethal effects of chemicals on the stages and species tested. OECD 210 also helps provide a value for the estimation of the chronic lethal and sub-lethal effects of the chemical on other fish species.

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.
