Coal-tar sealant, a commonly used application in parking lot and other pavements, is known to be harmful to humans, and threatens to enter watersheds and Great Lakes waterways as well. That is why lawmakers in three Great Lakes states are considering or proposing a ban on the substance in order to protect those waters. 
 
“Negative effects on fish and other aquatic animals include inhibited reproduction, fin erosion, liver abnormalities, cataracts and death, according to Geological Survey reports.
 
Coal-tar sealcoat makes up about half of the PAHs in lake sediment, according to Environmental Science and Technology. It is why PAH levels have increased in the sediment of urban and suburban lakes since 2000 even when other major PAH producers, like power plants, have been decreasing emissions.”
