With 200-ml water samples and 100-s counting times, the limit of detection is 0.7 渭g As l 1 . The method is applicable to all types of natural water including sea waters.doi:10.1016/S0003-2670(00)84978-8N.S.C BeckerV.M McRae...
The presence of silicate significantly reduced the arsenic removal efficiency of HIOPs, AA, and GFH, presumably due to the decrease in chemical binding affinity of arsenic in the presence of silicate. Additional experiments with natural types of water showed that, with the exception of IOC-M, ...

The study therefore used statistical and geochemical techniques to determine the hydrogeological water types and establish its relationships with arsenic. From the study, Arsenic concentration in surface water ranged from <0.001 mg/l to 7.900 mg/l, whilst in groundwater, it ranged from <0.001 mg/...
The As and F contamination results from water–rock interactions and may be accelerated by geothermal and mining activities, as well as by aquifer over-exploitation. These types of contamination are particularly pronounced in arid and semi-arid regions, where high As concentrations often show a ...
the different types of filter systems were effective in reducing arsenic levels in the drinking water by more than 10%. Because all available filter systems were of different 1 Health Canada has defined the term “essentially negligible” as a range from one new cancer ...
Almost 70 years after the suspension of the mining activity, As levels in water remain high. The results indicated a strong As contamination in fish collected downstream from the mine. The operculum, liver, and gills showed the highest As concentrations whereas levels in muscle were lower. A ...
The arsenic remaining in the water used for soaking was also measured. Arsenic was detected in all samples with total arsenic at concentrations ranging from 18 to 124 mg/kg. Inorganic arsenic, which can cause liver cancer, was only found in the nine samples of hijiki seaweed that were ...
