Pesticides may drastically shorten fish lifespans, study finds
- A Science study finds chronic, low-dose pesticide exposure may accelerate ageing in fish.
- Researchers linked chlorpyrifos, banned in parts of the world, to shortened telomeres in fish.
- The affected fish populations showed signs of accelerated biological ageing at concentrations below safety standards.
- Experts warn that ageing signs could have broader implications for other organisms, including humans.
- The study combined field data from over 20,000 lake sky-gazer fish with lab experiments.
- Researchers found lipofuscin buildup in livers as an ageing marker in contaminated fish.
- Chlorpyrifos was the only compound consistently linked to ageing signs in tissues.
- The study suggests safety checks should extend beyond short-term toxicity tests.
- Older fish are crucial for reproduction and population stability, making ageing impacts more significant.
- The findings could have ecosystem-wide consequences if similar ageing effects occur in other species.
