Methylmercury and dissolved organic carbon relationships in a wetland-rich watershed impacted by elevated sulfate from mining.

Methylmercury (MeHg), dissolved organic carbon (DOC), and sulfate (SO(4)(=)) relationships were investigated in the mining-influenced St. Louis River watershed in northeast Minnesota. Fewer wetlands and higher SO(4)(=) in the mining region lead to generally lower availability and solubility of DOC in mining streams compared to non-mining streams.

Nursing considerations for patients requiring cardiopulmonary support.

The number of patients receiving cardiopulmonary support (CPS) is increasing, requiring critical care nurses to be better prepared to care for these complex patients. Background information on CPS along with considerations for nursing management are presented. A case study of a patient requiring CPS and a suggested nursing care plan are included to assist in providing quality nursing care.
