化学品 鱼类胚胎和卵黄囊仔鱼阶段的短期毒性试验
Application Summary AI generated
This standard specifies a laboratory method for assessing the acute toxicity of chemical substances to the early life stages of fish, specifically during the embryo and sac-fry (yolk-sac larvae) phases. It is applied in environmental risk assessment and regulatory testing to evaluate the potential harmful effects of industrial chemicals, pesticides, and other pollutants on aquatic ecosystems. The test is conducted under controlled conditions to determine the concentration that causes lethal or sub-lethal effects, supporting chemical classification and environmental safety decisions.
