In a 160-day full life cycle (FLC) study of the freshwater Zebrafish (Danio rerio) with TGAI, the no observed adverse effect concentration (NOAEC) was non-definitive (i.e., NOAEC 306 g a.i./L) and was based on a 5-8% reduction in F0 spawning male and female length, 13% reduction in F0 spawning female weight, and 9% reduction in F0 4-week post-hatch length at the LOAEC of 306 g a.i./L (the lowest test concentration). The aim was to assess the effects of continuous exposure to ethofumesate technical on different life stages of zebrafish (Danio rerio) during a life cycle, including early life stages, juvenile growth, reproduction of the parental generation (P generation) and the early life stages of the filial generation (F1-generation). However, this study (MRID 50279402) was classified as supplemental in the EPA risk assessment since it did not test low enough and the NOAEC was established as 306 g a.i./L.
Non
The endpoint values in the fish full life cycle study were originally evaluated in the EPA risk assessment for ethofumesate. Therefore, this study information does not impact the current risk assessment for Canada.
