Transcriptomic and Metabolomic Analyses Reveal Intestinal Lipid Metabolic Disturbance in Loaches Co-Exposed to Polystyrene Nanoplastics and Imidacloprid

Summary

Scientists found that when fish (loaches) were exposed to both tiny plastic particles (nanoplastics) and a common pesticide called imidacloprid, their gut cells struggled to process fat normally, causing changes at the genetic and metabolic level. This matters because these same pollutants are widespread in our water and food supply, and this study suggests that combined exposure to plastics and pesticides could disrupt fat metabolism in ways that single-pollutant studies might miss—raising questions about similar risks for human health.
