Emissions from Doe Run Peru’s La Oroya facility and blood lead levels among workers and in the community have improved significantly, the company reported Wednesday. “When we bought the lead smelter in 1997 we committed to working to address the 75 years of health and environmental issues left by the previous owners,” said Doe Run Peru President Bruce Neil. “The work we have been doing over the last seven years in partnership with the community has resulted in real progress.”
