UC expert: More oil production means more leaks

UC College of Arts and Sciences Professor Amy Townsend-Small told the Enquirer that both chemicals are byproducts of oil. She teaches in UC's School of Environment and Sustainability.

“These train cars that we see throughout Cincinnati, they’re all carrying petrochemicals,” she said.

Styrene is an organic molecule that's used in making Styrofoam and other plastics, she said.

It's considered a likely carcinogen, according to the National Research Council.

Townsend-Small said the likelihood of rail accidents increases with the increase in rail use. Ohio ranks fourth in the nation in miles of active freight rail, according to the Association of American Railroads.

And as the United States turns to greener transportation, gas and oil companies are dedicating more petrochemicals to plastics production, Townsend-Small said.

The Ohio River is home to dozens of oil, gas and petrochemical facilities.
