The plant is also setting new standards in the area of backward integration, obtaining all the important precursors such as acrolein and methyl mercaptan from its own raw materials production facilities.
Monitors also were tracking high levels of other toxic chemicals, including formaldehyde, carbon tetrachloride, acetaldehyde and acrolein.
At the 15 schools — in Alabama, California, Kentucky, Michigan, Mississippi, New York, Ohio and South Carolina — regulators found average acrolein levels at least 100 times higher than what the government considers safe for long-term exposure.
EPA spokesman Brendan Gilfillan said the initial readings show "more must be done to reduce the amount of acrolein the American people, especially children, are exposed to."
"We've had a very marvelous day today, but this is a concern," he said of the acrolein levels.
The chemical that once was weaponized, acrolein, can exacerbate asthma and irritate the eyes and throat.
At Spain, the EPA samples showed high levels of one chemical, acrolein, which exacerbates asthma.
•Tests outside at least 15 schools detected high levels of acrolein, a chemical that can irritate the eyes and throat, and that — in a far more potent form — had been used as a chemical weapon during World War I.
Studies have also shown that ozone reacts with scented cleaners, air fresheners, and other household products to produce potentially harmful substances like formaldehyde, a carcinogen; acrolein, a toxic irritant; and ultrafine particles.
I found that burning polyethylene emits fumes that include compounds such as methane, ethane, aldehydes, ketones and acrolein, plus additional compounds.
