Lake acidification: Its effect on lead in the sediment of two Adirondack lakes

Sediment cores from two remote lakes, Sagamore and Woods (Adirondack State Park, New York), were analyzed for lead. A marked increase was found in the top 10 cm of the sediment of both lakes. The effect of lake acidification on the release of lead from the sediments was determined in laboratory stud...

Zusammenfassung:Sediment cores from two remote lakes, Sagamore and Woods (Adirondack State Park, New York), were analyzed for lead. A marked increase was found in the top 10 cm of the sediment of both lakes. The effect of lake acidification on the release of lead from the sediments was determined in laboratory studies. Significant lead desorption (>5% of the total) only occurred at a pH
