Pollution Linked To Genetic Damage

Soot possibly linked to genetic damage

Scientists say breathing soot from factories or highways might cause genetic damage. It is not known yet if people can inherit pollution-damaged DNA that can harm their health. The discovery from experiments on mice comes as scientists already are calling for more research into the dangers of particulates -- microscopic soot particles linked to health problems, including asthma and heart disease. The study was conducted under the auspices of the National Academy of Sciences.
