"TONAWANDA, N.Y. — State environmental officials say air sampling shows there’s been a drop in the chemical benzene since the closure of the Tonawanda Coke plant in western New York.
A Department of Environmental Conservation analysis of the air quality around the site shows an immediate drop in cancer-causing benzene following the shutdown of the 100-year-old plant in October. The DEC said earlier this week while releasing the results that it found no concerning chemical concentrations."
