Arsenic is a naturally occurring element found widely in the environment. However, on recent days the level of arsenic in the environment has increased several folds due to its use as pesticide, defoliant, electronics, thermal power plants, wood preservatives and metal industry. Arsenic has been reported as one of the most alarming chemical in the environment [1], present in different forms and...

Accuracy in trace level clinical or biomedical analyses is of increasing importance as populationbased surveillance is more widely used to address issues of nutritional requirements, environmental exposures, and epidemiological outcomes. Among the uses of such surveillance, evaluation of community exposures from a local arsenic pollution source is one example. Urinary biological monitoring is a...

In this study, the binding of amlodipine (a Ca ++ channel Blocker) and arsenic (metalloid) to bovine serum albumin (BSA) was studied by equilibrium dialysis(ED) method in order to have an insight into their binding chemistry to BSA. Free amlodipine concentration was increased due to addition of arsenic which reduced the binding of the compounds to BSA. However, the free fraction was not increa...

BACKGROUND Established causes of diabetes do not fully explain the present epidemic. High-level arsenic exposure has been implicated in diabetes risk, but the effect of low-level arsenic exposure in drinking water remains unclear. OBJECTIVE We sought to determine whether long-term exposure to low-level arsenic in drinking water in Denmark is associated with an increased risk of diabetes using...

Arsenic is a toxic metalloid existing widely in the environment, and its removal from contaminated water has become a global challenge. The use of bacteria in this regard finds a promising solution. In the present study, Exiguobacterium sp. As-9, which is an arsenic resistant bacterium, was selected with respect to its arsenic removal efficiency. Quantification of arsenic in the water treated w...

Arsenic (As) is widespread in the environment and causes numerous health problems. Rhodopseudomonas palustris has been regarded as a good model organism for studying arsenic detoxification since it was first demonstrated to methylate environmental arsenic by conversion to soluble or gaseous methylated species. However, the detailed arsenic resistance mechanisms remain unknown though there are a...

The Binational Arsenic Exposure Survey (BAsES) was designed to evaluate probable arsenic exposures in selected areas of southern Arizona and northern Mexico, two regions with known elevated levels of arsenic in groundwater reserves. This paper describes the methodology of BAsES and the relationship between estimated arsenic intake from beverages and arsenic output in urine. Households from eigh...

Arsenic, a semi-metal, colourless, tasteless and odourless toxic element, is known as the “King of Poison” at present. Arsenicosis is a well-known chronic disease which occurs due to drinking of arsenic contaminated tube well water having arsenic level exceeding the normal level for a prolonged period. It is likely to create a significant health impact ranging from skin lesions to cancer culmin...

High arsenic in natural groundwater in most of the tubewells of the PurbasthaliBlock II area of Burdwan district (W.B, India) has recently been focused as a serious environmental concern. This paper is intending to illustrate the statistical modeling of the arsenic contaminated groundwater to identify the interrelation of that arsenic contain with other participating groundwater parameters so t...

BACKGROUND Rice is known to be high in arsenic, including in infant rice cereal. Although arsenic in drinking water is currently regulated, there are currently no US regulations regarding arsenic concentrations in food. OBJECTIVE We used published values to estimate arsenic exposure via rice cereal relative to breast milk or formula for 6- to 12-month-old infants in the general US population....
