Metals found in mussel shells expose long- term effects of oil and gas wastewater

摘要

Researchers from Pennsylvania State University (University Park) and Union College (Schenectady, N.Y.) have discovered elevated concentrations of strontium, a metal linked to wastewater produced during oil and gas extraction, in the shells of freshwater mussels. This metal was found downstream from former hydraulic fracturing wastewater disposal sites in Pennsylvania.
