摘　　要：In this research,the single and combined toxicity effects of two commonly used pesticides,lambda-cyhalothrin and deltamethrin,were investigated on zebrafish at 20℃,with a weight of(1±0.1)g and a length of(3.5±0.35)cm.The study revealed that lambda-cyhalothrin exhibited higher toxicity compared to deltamethrin.Additionally,when used together,these pesticides showed significantly increased toxic effects on zebrafish.The 96-h LC 50 values were determined to be 3.059μg/L(confidence limits 0.077-0.351μg/L)for lambda-cyhalothrin and 1.304μg/L(confidence limits;0.046-0.228μg/L)for deltamethrin,both demonstrating a significant positive correlation(P<0.05).These results underscore the importance of regulating and managing pesticide use to safeguard aquatic organisms and uphold environmental sustainability.
