History of mercury loading in the Upper Mississippi River reconstructured from the sediments of Lake Pepin

Article Abstract:

An analysis of the mercury loading in Lake Pepin, which is located on the Upper Mississippi River, can help described how the river has been managed over a number of years. In fact, the analysis showed that the implementation of pollution control efforts since about 1970 has had a pronounced effect on the amount of mercury accumulation in the sediment at Lake Pepin.

Decreasing mercury in northern Wisconsin: Temporal patterns in bulk precipitation and a precipitation-dominated lake

Article Abstract:

The amount of mercury in Wisconsin's Little Rock Lake decreased 40% from 1988 through 1999, possibly meaning that the amount of mercury in the area's precipitation has also decreased.
