You’ve probably smelled it — the overpowering, nostril-burning stench when new coal-tar pavement or sealant is being laid on a driveway, street, parking lot or playground. And you may have idly wondered how toxic the shiny black liquid spray might be, but moved on to other things because, after all, what can you do about it?
As it turns out, it is toxic. The substances contain polycyclic aromatic hydrocarbons (PAHs).
One recently released study1 by the U.S. Geological Survey (USGS) and Milwaukee Metropolitan Sewerage District identified coal-tar sealants as the primary source of PAHs and called them “a major source of contamination in urban and suburban areas and a potential concern for human health and aquatic life.”2
The problem finally made headlines when toxic coal-tar sealants were found to be responsible for up to 94 percent of the PAHs found in 40 samples of streambed sedimentpost was originally published on this site
