Concentration and distribution of selenium associated with irrigation drainage in the Western United States


, : Concentration and distribution of selenium associated with irrigation drainage in the Western United States. Proceedings of the United States People' s Re ic of China bilateral symposium on droughts and arid region hydrology September 16-20, 1991, Tucson, Arizona: 113-123

Concentrations, distributions and sources of selenium from irrigated lands were studied between 1986 and 1990 at 20 reconnaissance study areas in the western states of USA as part of the Department of the Interior's National Irrigation Water Quality Programme. Samples of water, bottom sediment, whole-body fish and bird livers were collected before, during and after irrigation seasons from streams, canals, lakes and groundwater in each area.

Eight psoriatic patients undergoing treatment with dithranol were studied. Using cell kinetic and histological data it was shown that retention of dithranol pigment and a return of dermatoglyphics are valid signs of treatment response in psoriasis...
