Common dolphins in New Zealand are exhibiting biological ages exceeding their chronological ages, potentially due to exposure to trace metals and "forever chemicals."
The study focuses on common dolphins in New Zealand. Researchers have found that these dolphins appear biologically older than they actually are based on their calendar age. This premature aging is raising concerns about the health of the dolphin population.
The research suggests that a combination of factors may be contributing to this phenomenon, specifically trace metals and "forever chemicals." These substances accumulate in the dolphins’ tissues over time, potentially accelerating the aging process. The source does not specify *how* these chemicals accelerate aging, only that they *may* be to blame.
The term “forever chemicals” refers to per- and polyfluoroalkyl substances (PFAS), which are known for their persistence in the environment and bioaccumulation in living organisms. These chemicals have been linked to various health problems in both humans and animals.
