This paper investigates the effect of drinking arsenic contaminated water on mental health. Drinking water with an unsafe arsenic level for a prolonged period can lead to arsenicosis and associated illness. Based on rich and newly collected household survey data from Bangladesh, we construct several measures for arsenic contamination that include the actual arsenic level in the respondent’s tub...

epidemiological data suggest that arsenic ultimately results in cancer in different parts of the body. several synthetic therapeutic agents manifest inadequate potency with severe side effects against arsenic toxicity. the flesh of b. bengalensis , has long been used as an ethno-medicine in case of arthritis, blood-impurities, impaired immune system, conjunctivitis and liver anomalies. this pot...

This review examines the scientific literature on the environmental concerns of arsenic additives in poultry litter. A number of questions were addressed on this issue. In summary, the review found: 1) Does arsenic from poultry feed amended with roxarsone end up in poultry litter? The arsenic found in poultry feed ends up in the poultry litter. Poultry litter from chickens receiving feed withou...

The subchronic treatment of mature female Wistar-strain albino rats in diestrous phase with sodium arsenite at a dose of 0.4 ppm/100 g body weight/rat/day via drinking water for period of 28 days (seven estrous cycles) caused a significant reduction in the plasma levels of leutinizing hormone (LH), follicle-stimulating hormone (FSH), and estradiol along with a significant decrease in ovarian ac...

The extent of and factors controlling arsenic penetration into the central nervous system (CNS) remain unclear. Elemental arsenic levels in 67 paired cerebrospinal fluid (CSF) and plasma samples from 9 patients with acute promyelocytic leukemia (APL) on oral arsenic trioxide (As2O3), obtained during intrathecal chemotherapy (treatment of CNS APL, n = 6; prophylaxis, n = 3) were measured. Median...

An investigation was made into a disease involving skin pigmentation, keratosis of the hands and feet, dental discoloration, and generalized bone and joint pain, stiffness and rigidity, in the village of Bazhi, Zhijin County, Guizhou Province, People's Republic of China. Measurements were made of the arsenic and fluoride levels of coal, water, air, food, urine and hair in Bazhi and a control vi...

The presence of toxic level of inorganic arsenic in groundwater used for drinking in Bangladesh and neighboring India is unfolding as one of the worst natural disaster in the region. The purpose of this work is to ascertain the chemical fate of arsenic and other metals in groundwater of Bangladesh. A combination of techniques was used to measure 24 metals, 6 anions, Eh, pH, dissolved oxygen, co...

Arsenic is an important environmental carcinogen that affects millions of people worldwide through contaminated water supplies. Genotoxicity of arsenic has been a topic of controversy. Both genetic alterations (mutations) and epigenetic changes (methylation) have been shown to play a crucial role in environmental carcinogenesis. Chronic exposure to arsenic has been shown to induce malignant tra...

We review recent publications by Hopenhayn-Rich et al. and Smith et al. regarding two critical issues in arsenic risk assessment: the role of methylation in the dose-response relationship and the role of internal cancers. Hopenhayn-Rich et al. applied simple linear regression to data from several studies to determine whether the percentage of inorganic arsenic in urine increases with increasing...
