Adsorption of trichloroethene at the vapor/water interface

Article Abstract:

The environmental pollutant trichloroethene (TCE) is studied at the vapor/water interface using surface tension reductions as a measure of TCE adsorption. Charts of vapor-phase TCE pressure in relation to surface pressure and interface excess (taken from the Gibbs relative interface excess equation) show the results of the study.

Distribution and fate of neutral alkylphenol ethoxylate metabolites in a sewage-impacted urban estuary

Article Abstract:

Alkylphenol ethoxylates (APEOs) are measured in the water, suspended particles, and sediments of the Jamaica Bay, Long Island, New York estuary with an LC-MS method. The movement of APEOs is charted, showing a correlation with pollution from wastewater sources.

Rain deposition of pesticides in coastal water of the South Atlantic Bight

Article Abstract:

Contamination of South Carolina coastal waters by rain water flushing pesticides is examined. Readings were taken from four locations between the mouth of the Savannah River and Cape Fear during a major rain storm. The storm produced 200-300mm in the coastal region. Surface samples were taken at the mouths of the Savannah, Copper, Santee, and Pee Dee Rivers, and well out to sea. In all samples were taken at 19 locations. Concentrations of atrazine, metolachlor, and trifluralin were detected. These pesticides are designed to break down quickly in the environment. However, with their high solubility, they can still adversely impact the environment at great distances from where they were applied. The authors argue that the impact of rain upon pesticide deposition in coastal regions and ocean must be included when investigation pollutant impact in the region.
