"Ohio Leads List Of Top 20 States With Toxic Air"

"People living in Ohio, Pennsylvania and Florida are most at risk in the United States from toxic emissions spewing from coal and oil-fired power plants, two leading American environmental groups said in a report on Wednesday.

Electricity generation and chemical processing were the top culprits for dangerous emissions, which can lead to or worsen ailments such as asthma and cancer, according to the report by the Natural Resources Defense Council and Physicians for Social Responsibility.

While Ohio topped the list of 20 states most affected by toxic air pollution, Kentucky and Maryland were ranked fourth and fifth. Next were Indiana, Michigan, West Virginia, Georgia and North Carolina.

"Power plants are the biggest industrial toxic air polluters in our country, putting children and families at risk by dumping deadly and dangerous poisons into the air we breathe," said Dan Lashof, director of the climate center at the Natural Resources Defense Council."
