Reports

Coal-fired power plants are the single largest source of mercury pollution in the United States. Emissions from these plants eventually make their way into Michigan’s waterways, contaminating fish and wildlife.

This report ranks cities in Michigan and across the country for the number of days when the air was unhealthy to breathe due to smog pollution last year and this summer, and includes new data showing that the problem is even worse than the public thought. The research shows that on six additional days last year, Detroit-area residents were exposed to smog levels that a national scientific panel has found to be dangerous to breathe. Yet, because of outdated federal air quality rules, those at risk were never alerted to unhealthy air levels.
