Tens of thousands of deaths linked to weak US air pollution rules – study

Researchers linked nine causes of death with a certain type pollution when reviewing medical records of deceased veterans

US air pollution rules could be hugely insufficient in preventing deaths, experts are concluding from a new study of the likely causes of death of 4.5 million veterans.

Published in the peer-reviewed journal Jama, the research finds that 99% of deaths from illnesses linked to a certain type of air pollution occur in people who are exposed to lower levels than the Environmental Protection Agency (EPA) currently deems acceptable.
