Recently, U.S. scientists noted that stray dogs near the site of the Chernobyl nuclear disaster showed immunity to radiation, heavy metals and pollution. Scientists collected blood samples from 116 stray dogs and found that two populations were genetically significantly different from neighboring dogs and had adapted to long-term exposure to toxic environments of radiation, heavy metals and pollution, a finding that could help study the effects of long-term exposure to multiple environmental hazards on human health.
