Long-term pesticide exposure speeds up aging in fish
Long-term pesticide exposure speeds up aging in fish Long-term exposure to low levels of chlorpyrifos, a common agricultural pesticide, can accelerate physiological aging and shorten lifespan in fish. The study, led by University of Notre Dame biologist Jason Rohr, found that chronic exposure to chlorpyrifos caused fish to age faster at the cellular level, as […]
