Radioactivity Levels in Some Sediments and Water Samples from Qarun Lake by Low–Level Gamma Spectrometry
The specific activities of the natural radionuclides U, Ra, Th and K were measured in sediments and water samples collected from the Qarun lake (Middle Egypt) in order to gather information about radionuclides mobility and distribution. In the sediment and water in general, the concentration of U was found to be higher than that of the Th and the activities of Th, Ra and U in this lake falls wi...

15 صفحه اول[Organic pollutant residues of different origins in Navarra].
An analysis was made of residues of polychlorobyphenyls and trihalomethanes through GC-ECD and of herbicides through HPLC-PAD in samples proceeding from Navarra. Polychlorobyphenyls were detected (0.30 +/- 0.05 and 0.11 +/- 0.05 microg/l) in two of the 106 water samples analysed. Sixty-six food samples were analysed, and polychlorobyphenyls were only found in 8 samples of trout (dissimilar to d...
متن کاملMeteorological drought monitoring using several drought indices (case study: Salt Lake Basin in Iran)
Drought detecting is a necessary aspect of drought risk management. It is generally performed usingdifferent drought indices that are effectively continuous functions of rainfall and other hydro- meteorologicalvariables. A number of drought indices have been introduced and used in various countries to date. In thecurrent research, four meteorological drought indices including the standardized p...
متن کاملDaytime Photochemical Pollutant Transport over a Tributary Valley Lake in Southwestern British Columbia
Tethersonde, lidar, aircraft, and surface chemistry measurements from an intensive field campaign (Pacific ’93) in the Lower Fraser Valley (LFV) demonstrate the daytime advection of pollutants into a lake-filled valley adjoining a broad urbanized coastal valley. On three separate days (immediately before, during, and after a pollutant episode), elevated concentrations of ozone (O3) in the narro...
