Arsenic Analysis In Water

Arsenic contamination of ground water is found in many countries throughout the world including the us.

Arsenic analysis in water.

In human beings chronic arsenic exposure can culminate into lethal diseases such as cancer. The detection range of interest is 10 to 50 µg l the typical range of national standards for arsenic. Insoluble suspended arsenic accounted for about 3 of the total arsenic in the water from the three wells and ultrafiltration revealed that about 11 of the soluble arsenic mainly as iii was associated with molecules of molecular mass greater than 300 000 daltons. Although the world health organisation has set the maximum provisional value for arsenic in drinking water at 10 parts per billion yet concentrations as high as 5000 parts per billion are still reported.

Specialised techniques are needed to tell whether arsenic is present as arsenite or arsenate. Maximum concentrations of naturally occurring arsenic in groundwater can exceed 1000 µg l. This method is for determination of total inorganic arsenic as arsenite as arsenate as 5 monomethylarsonic acid mma and dimethylarsinic acid dma in filtered and unfiltered water and in tissue by hydride generation and quartz furnace atomic absorption detection. The most selective and sensitive methods for determination of total arsenic and its spe cies in water are coupled.

The who provisional guideline value for arsenic in drinking water is 10 μg l. Therefore the world health organization who has set the guideline concentration for arsenic in drinking water at 10 µg l 1 who 2011. The usgs studies local and national sources of arsenic to help health officials better manage our water resources. Furthermore arsenic in drinking water case solution analysis it allows the stakeholders to see the other options if the given set of alternative does not work thus saving the time effort and the working from scratch hence making it cost effective in nature.

Arsenic is a naturally occurring element but long term exposure can cause cancer in people. The world health organization recommends limiting arsenic concentrations in water to 10 μg l although this is often an unattainable goal for many problem areas due to the difficult nature of removing arsenic from water sources. As the instrument can measure arsenic down to ppt levels it is ideally suited to the determination of arsenic in water drinking water and other waters such as wastewater groundwater and sea water.
