Project Title:

Total Mercury, Methylmercury and Other Toxic Heavy Metals in Lake Pontchartrain Basin

Principal Investigator(s):

R.D. DeLaune

Project Location:

Lake Pontchartrain and Lake Maurepas.

Project Description

The research conducted consist of a study of mercury, methylmercury, and heavy metal content in sediment collected in a grid sampling in Lake Pontchartrain and Lake Maurepas. The sediment collected was analyzed for total mercury, methylmercury, and other heavy metals. Sediment samples were collected on 5 mile sampling grid in Lake Pontchartrain and Lake Maurepas. In addition to mercury, the sediment samples were analyzed for organic carbon content, pH, redox potential, grain size and the concentrations of other toxic heavy metals (lead, arsenic, nickel, cadium and zinc). A more detailed description of the sampling and analytical procedures are given in the section below on Experimental Methods.
