Pesticides may drastically shorten fish lifespans, study finds
Even low levels of widely used agricultural chemicals were linked to accelerated ageing, research suggests
TL;DR
- Pesticides can drastically reduce the lifespan of fish, even at low levels.
- Chronic low-dose exposure to pesticides accelerates signs of aging in fish, such as shortened telomeres and lipofuscin deposition.
- These aging effects occurred at concentrations below current US freshwater safety standards.
- Short-term exposure to high doses of pesticides causes toxicity and death but does not lead to the observed aging effects.
- The study suggests current chemical safety regulations, which focus on short-term high-dose exposure, may be insufficient.
- The researchers warn that similar aging-related risks could occur in humans due to chronic low-dose chemical exposure.
- Reduced fish lifespan can negatively impact reproduction, genetic diversity, and population stability.
