Significant negative correlation was found between arsenic concentration inwater and that in sediments(r=0.356r0.05(1, 50)=0.273), which might due to the dilution, sedimentation and biochemical effects in the water systems. 展开 被引量: 4 ...
Large-scale water resources management within the framework of GLOWA-Danube. Part A: The groundwater model The research project GLOWA-Danube, financed by the German Federal Government, is investigating long-term changes in the water cycle of the upper Danube riv... R Barthel,V Rojanschi,J Wo...
BEIJING, Jan. 2 (Xinhua) -- Algae blooms may accelerate the release of arsenic, a toxic substance that pollutes freshwater, according to a recent Chinese study. Many Chinese lakes have been plagued by eutrophication of water and outbreaks of blue-green algae in recent years. At the same time...
Altogether, 50 to 60 million use groundwater which very likely contains more than 50 micrograms per liter. "This is an alarmingly high number, which demonstrates the urgent need to test all drinking water wells in the Indus Plain," first author Joel Podgorski, a geophysicist at the Swiss Fede...
Water samples from a number of lakes and estuaries, mostly in California, showed measurable concentrations of methylated arsenic (equivalent to 1-59% of total As) with the exception of one highly alkaline lake. Neither depleted phosphate concentrations nor high dissolved salts correlated with the app...
Arsenic in groundwater in six districts of West Bengal, India: The biggest arsenic calamity in the world: The status report up to August, 1995 In six districts of West Bengal: Malda, Murshidabad, Bardhaman, Nadia, 24-Parganas (North) and 24-Parganas (South), arsenic has been found in ...
A review of the occurrence and cycling of arsenic in fresh waters is presented. The fate of arsenic in natural waters has received little attention in past years, in spite of the fact that arsenic is toxic and probably carcinogenic through exposure by drinking water.The chemistry of arsenic in...
A review of published information on the arsenic contamination of groundwater in the Terai regions of Nepal showed that the source was mainly geogenic due to the dissolution of the arsenic-bearing minerals. Clinical observations of patients in the arsenic affected districts revealed chronic arsenic poi...
Because the lake is a result of damming, it is perched above the water table and therefore As transport may occur via downward movement of porewaters and/or groundwaters. Preliminary evidence for this was found in the form of iron flocculates enriched in As which were found in surface ...
