Underground water in many regions of the world is contaminated with high concentrations of arsenic and the resulting toxicity has created a major environmental and public health problem in the affected regions. Chronic arsenic exposure can cause many diseases, including various physical and psychological harms. Although the physical problems caused by arsenic toxicity are well reported in liter...
Nanomagnetite can be synthesized in lab by decomposition method using FeOOH and oleic acid in 1-ODEbut the cost of production is very high. Here we are trying to synthesize cost effective nanomagnetites by using common materials present in our daily life which are freely available in market .Magnetite nanocrystals are highly useful in arsenic remediation as arsenic contamination in groundwater ...
Issue of arsenic contamination in drinking water in Terai belt has been a prevalent phenomenon in Nepal. So, this study has been conducted to visualize the status of arsenic contamination in ground water in Dang district located at central west Terai in Nepal. A total of 26,878 Tubewells and Dugwells were tested in 36 Village Development Committees (VDCs) using HACH arsenic testing field kit an...
Among the heavy metals, arsenic is known as a carcinogen material and its high concentrations in the ecosystem can be a major concern for public health and environment. The aim of this study was to evaluate the risk map of arsenic contamination and the possibility of its entering into the food chain using the fuzzy method in the central part of the Hamedan-Bahar plain. For this purpose, arsenic...
Background: Contamination of fruit juices with heavy metals presents a risk for human health. Concentrations of lead, and arsenic in fruit juices of market in Mashhad, Iran, were measured using atomic absorption spectrometry (AAS). Methods: Fifty varieties of commercial fruit juices (grape, apple, orange, pomegranate, and multi-fruit) from 5 popular brands (A, B, C, D and E) were purchased fro...
Arsenic contamination in groundwater in Bangladesh has become an additional concern vis-à-vis its use for irrigation purposes. Even if arsenic-safe drinking-water is assured, the question of irrigating soils with arsenic-laden groundwater will continue for years to come. Immediate attention should be given to assess the possibility of accumulating arsenic in soils through irrigation-water and i...
Arsenic contamination of rice by irrigation with contaminated groundwater and secondarily increased soil arsenic compounds the arsenic burden of populations dependent on subsistence rice-diets. The arsenic concentration of cooked rice is known to increase with the arsenic concentration of the cooking water but the effects of cooking methods have not been defined. We tested the three major rice ...
The arsenic (As) exposure represents an important problem in many parts of the World. Indeed, it is estimated that over 100 million individuals are exposed to arsenic, mainly through a contamination of groundwaters. Chronic exposure to As is associated with adverse effects on human health such as cancers, cardiovascular diseases, neurological diseases and the rate of morbidity and mortality in ...
Background and Aims: The critical aim of this study was to evaluate the effects of breast-milk contamination with Nickel and Arsenic, as well as aflatoxin M1 (AFM1) on the milk levels of IL-6 and IL-8. Materials and Methods: Breast milk was collected from 76 mothers on the 30th day post-parturition and milk levels of AFM1, Nickel, Arsenic, IL-6 and IL-8 were evaluated. Results: The results s...
A major environmental tragedy of modern times is the widespread arsenic contamination of shallow drinking water wells in rural Bangladesh which went unrecognized for years. Large numbers of people are now starting to show a range of symptoms long associated with chronic arsenic exposure. Rural families in Bangladesh, one of the poorest countries in the world, face financial risks from major ill...
