Academy of Natural Sciences of Drexel University - Collections and Research - Patrick Center For Environmental Research - Biogeochemistry


The Biogeochemistry Section of the Patrick Center is concerned with the influence of aquatic organisms on the sources, fate and transport of chemicals in aquatic systems. Studies frequently deal with the carbon and nutrient cycling as well as those of trace elements (e.g., lead, copper, mercury, and zinc) and organic contaminants such as polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs). The section regularly provides water, sediment and tissue analyses for government, intergovernmental agencies, and private companies from around the country. In addition to the sediment core project mentioned above, it has recently studied the effects of small dams on sediment contaminants, photochemical transformation of marsh-derived dissolved organic matter, and sedimentation and eutrophication in salt marshes.
