    ). The data were collected during May - December , as part of a study being conducted by the U.S. Geological Survey to investigate applications of CFC's as tools for age-dating ground water. DATA ON CHLOROFLUOROCARBON CONCENTRATIONS The wells sampled were selected from a monitoring network established by the by: 8. a thinning of stratospheric ozone that occurs over the poles during the spring polar stratospheric clouds a cloud that forms at altitudes of ab m during the Arctic and Antarctic winter or early spring, when air temperatures drop below C.

    This report examines alternative ways to implement marketable permits in the case of chlorofluorocarbon (CFC) regulations currently under consideration by the U.S. Environmental Protection Agency. The authors examine alternative strategies for administering marketable permits under a CFC by: 1. ADVERTISEMENTS: Read this essay to learn about the smuggling of CFC which is an ozone depleting substance. The gases, mainly chlorofluorocarbons, or CFCs, are used in air conditioning and refrigerators. Scientists say their continued use – particularly in populous developing counties—could undo efforts to replenish the ozone layer under the Montreal Protocol.

    CHLOROFLUOROCARBONS Chlorofluorocarbons (CFCs) are a class of chemicals that contain only atoms of carbon, chlorine, and fluorine. As a group, they are unreactive, stable, and poorly soluble in water. Commercially, the most important CFCs were derivatives of methane and ethane. Total carbon dioxide, hydrographic, and nitrate measurements in the southwest Pacific during austral autumn, results from NOAA/PMEL CGC cruise (Book).
