A Health Canada-led study of mice has confirmed that pollution wafting off highways and out of steel mills triggers sperm mutations that can be passed to the next generation.Polluted air near Hamilton Harbour lead to a significant increase in sperm mutations in the mice that breathed the dirty air for 10 weeks, according to the study published Monday in the U.S. Proceeding of the National Academy of Sciences. The authors conclude that the "potential health effects warrant extensive further investigation."
