If arsenic is present in water prevailing forms are inorganic acids of As(III) and As(V). oAs can be found in traces as monomethylarsenic acid, MMA(V), and dimethylarsenic acid, DMAs(V). Three types of resins: a strong base anion exchange (SBAE) and two hybrid (HY) resins: HY-...
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 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 ...
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 ...

Arsenic can be found as a contaminant in food and water sources. Shellfish and other seafood, as well as fruits, vegetables, and rice; are the foods most commonly contaminated. Arsenic poisoning typically occurs as a result of industrial exposure, from contaminated wine or illegally distilled spi...
This paper introduces the measuring method of arsenic in HJ 694-2014 uncertainty evaluation method, we find the main influencing factors affecting the measurement results, and the measurement uncertainty was evaluated. The results showed that the evaluation of the measurement uncertainty is the main sou...
Fig. 1. Arsenic contamination of drinking water in different parts of the world. Several types of cancer and other detrimental effects on human health due to chronic As exposure have been reported (Das and Sengupta, 2008, Ferreccio et al., 2013, Gibb et al., 2011, IARC, 2012, Islam et...
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 ...
