Co-exposure reveals toxic impacts on gene expression and oxidative stress in hook snout carp, suggesting pesticide regulations are necessary.

To investigate the combined toxic effects of lambda-cyhalothrin and difenoconazole on hook snout carp.
30-day co-exposure experiment using lambda-cyhalothrin and difenoconazole
Assessment of biochemical and molecular changes in hepatic tissues
Biochemical assays measuring catalase and caspase-3 activities
Gene expression analysis of specific markers
Both pesticides increased catalase and caspase-3 activities, indicating oxidative stress
The combination caused greater activation of enzymes compared to individual exposures
Gene expression showed downregulation of erβ1 and socs3a, and upregulation of cxcl-c1c in combined exposure
The findings suggest significant immunotoxic and endocrine-disrupting effects from co-exposure

Wang et al. (2025) studied this question.
