Arsenic removal by nanoparticles: a review SpringerLink

2015-3-21  Arsenic is a ubiquitous element in the environment. Because of its prevalence in nature and its toxicity, the potential for arsenic contamination of water, air, and soil from both geological and anthropogenic sources is a significant environmental health concern (Smedley and Kinniburg 2002; Ng et al 2003).Elevated concentrations in surface water and groundwater of up to 100–5000 μg L −1

Arsenic Removal from Drinking Water: Experiences with

Concern over the occurrence of arsenic (As) in drinking water has a long history. The effects of chronic As exposure have been well documented and have provided the basis for regulating As concentrations in drinking water (NRC 1999; U.S. EPA 1988).In the United States, a limit of 50 μg / L was first set for As in 1942 and is still the standard in some countries today (Mondal et al. 2013).
