CHICAGO - "Federal environmental regulators are cracking down on a Southeast Side company after finding high levels of brain-damaging manganese in a low-income, predominantly Latino neighborhood."

Air quality monitors posted around the S.H. Bell Co. storage terminal recorded violations of federal health standards during nearly 40 percent of the days when samples were collected between March and June, according to data posted online Monday by the U.S. Environmental Protection Agency.

Average concentrations of the heavy metal exceeded the legal limit of 0.3 micrograms per cubic meter of air during the period and spiked up to four times higher, prompting the EPA to cite S.H. Bell with violations of the federal Clean Air Act."
