Rohr7 Low concentrations of chemicals are widespread in the environment, but exploration of the effects of their chronic exposures on animal life span in the wild is limited. Field investigations showed that fish populations of lake skygazer (Culter dabryi) with chronic low-dose chlorpyrifos loads had shortened telomeres and truncated age structures. Laboratory experiments confirmed that chronic low-dose chlorpyrifos exposure induced telomere degradation and reduced survival in a dose- and physiological age–dependent manner, whereas acute high-dose exposure did not. …
