"Thinking of arsenic as not just a bad guy, but also as beneficial, has reshaped the way that I view the element," said first author Jaclyn Saunders, who did the research for her doctoral thesis at the UW and is now a postdoctoral fellow at the Woods Hole Oceanographic Institution and the Massachusetts Institute of Technology.
"We've known for a long time that there are very low levels of arsenic in the ocean," said co-author Gabrielle Rocap, a UW professor of oceanography.
According to the World Health Organization (WHO), long-term health effects such as skin lesions, diabetes and developmental defects are well-known consequences of arsenic
toxicity may develop insidiously after 6 months to 2 years or more depending upon the intake of arsenic-contaminated water or exposure.5
According to World Health Organisation (WHO), arsenic
is naturally found in soil and groundwater in many countries.
The study's findings showed that none of the food items were free of lead and arsenic
. The concentration of lead and arsenic
in tap water was 1.3ng/g and 2.5ng/g, respectively.
levels are widely used as biomarkers that reflect primarily recent intake of arsenic
(Xue et al.
Comparatively higher arsenic
contamination was found in districts of Multan, Bahawalpur, Kasur, Khanewal, Lahore, Vehari and Pakpattan, Dadu, Khairpur Mir, Matirai, Hyderabad and Sukkur, the study titled 'Arsenic
Monitoring and Mitigation Project' said.
A complete literature review on arsenic
contamination in groundwater and the resulting health effects is beyond the scope of this article.
As a matter of fact, it's important to control the mobility of arsenic
and its different forms present in leachate composts.
The obtained experimental results showed that efficiency of arsenic
and boron removal increased with increasing current density.
is used industrially as an alloying agent, as well as in the processing of glass, pigments, textiles, paper, metal adhesives, wood preservatives and ammunition.
All drinking/cooking water samples were found below the 10 ug/L arsenic
concentration which is the WHO provisional guideline values.
, which has no distinct taste or smell, is widespread in soil and groundwater in much of the world.
