Fu and Chang's idea includes the use of a novel
arsenic test design that is based on a porous substrate in which capillary flow enables instrument-free pumping of a water sample into the device.
The guideline value for
arsenic in drinking water given by World Health Organization (WHO) is 10 ppb whereas permissible limit by National Standards for Drinking Water Quality (NSDWQ) is 50 ppb.
Cooked samples of rice underwent dilute nitric acid extraction to liberate the total
arsenic content, as well as an in vitro assay that mimics the digestive process.
ICP-MS is very used in the determination of
arsenic, but the biggest drawback is possible interference due to the presence of chlorine in samples.
The health hazards (both carcinogenic and noncarcinogenic) associated with chronic intake of
arsenic due to drinking
arsenic contaminated water have been investigated and well known (Nickson, 1998; Acharyya, 1999; Ahsan, 2009; Argos, 2010; Shrestha, 2003; Smith, 2009; 1998).
Consumer Reports ' newest data, in addition to other reports, show that many rice products still have levels of
arsenic significantly above 5 ppb, including baby food and even organic brown rice syrup.
Ferric hydroxide coated new paper and pulp adsorbent was used in laboratory scale adsorption filters to remove
arsenic by coagulation phenomena.
This quality of
arsenic explains why it can be found in a wide variety of forms that make their way into an equally wide variety of ecological niches; it is actually unusual to encounter a natural setting where at least trace amounts cannot be detected.
Arsenic has a short half-life in the body; it is readily excreted in urine in 1-3 days (Calderon, Hudgens, Le, Schreinemachers, & Thomas, 1999; Chen, Amarasiriwardena, Hsueh, & Christiani, 2002; Karagas et al.
DIAGNOSIS: Diagnosis of peripheral neuropathy due to
arsenic poisoning was kept.
Numerous studies have shown the health effects associated with
arsenic in drinking water both within and outside the US.
The
arsenic content in the soil can be reduced by applying zinc and other compounds such as organic matter which have capability of binding with
arsenic.
