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...

Arsenic is a naturally occurring element, present in soil, ground water and plants. Regions with high geological occurrence of inorganic arsenic have been identified in particular in Asia and other non-European countries. In Europe, environmental arsenic levels are rather low, with the exception of distinct geological or industrial areas. Arsenic is a metalloid, displaying different valences (-...

BACKGROUND Arsenicals (roxarsone and nitarsone) used in poultry production likely increase inorganic arsenic (iAs), monomethylarsonic acid (MMA), dimethylarsinic acid (DMA), and roxarsone or nitarsone concentrations in poultry meat. However, the association between poultry intake and exposure to these arsenic species, as reflected in elevated urinary arsenic concentrations, is unknown. OBJECT...

Organic brown rice syrup (OBRS) is a sweetener frequently used as an alternative to high-fructose corn syrup in organic and health food products. In a study of children’s foods, a team of researchers discovered high levels of arsenic in toddler formula products that contained OBRS. Given evidence that arsenic accumulates in rice at high levels, the researchers suspected OBRS was the source of t...

Arsenic, chromium, and nickel are reported in several epidemiologic studies to be associated with lung cancer. However, the health effects of arsenic, chromium, and nickel exposures are equivocal for children. Therefore, we performed a cross-sectional study to investigate possible associations between the internal concentrations of arsenic, chromium, and nickel and the level of oxidative stress...

This paper presents views on the current status of (inorganic) arsenic risk assessment in the United States and recommends research needed to set standards for drinking water. The opinions are those of the Arsenic Task Force of the Society for Environmental Geochemistry and Health, which has met periodically since 1991 to study issues related to arsenic risk assessment and has held workshops an...

BACKGROUND Chromated copper arsenate (CCA)-treated wood has been widely used for outdoor play structures. There is a growing scientific concern about children's exposure to the arsenic that leaches from these structures. The purpose of this study was to measure arsenic from CCA-treated wood play structures owned by the City of Toronto to guide an appropriate exposure reduction strategy. METHO...

Inorganic arsenic is a strong carcinogen, possibly by interaction with the telomere length. The aim of the study was to evaluate how chronic arsenic exposure from drinking water as well as the arsenic metabolism efficiency affect the individual telomere length and the expression of telomere-related genes. Two hundred two women with a wide range in exposure to arsenic via drinking water (3.5-200...

BACKGROUND Arsenic has antimicrobial properties at high doses yet few studies have examined its effect on gut microbiota. This warrants investigation since arsenic exposure increases the risk of many diseases in which gut microbiota have been shown to play a role. We examined the association between arsenic exposure from drinking water and the composition of intestinal microbiota in children ex...

 The purpose of this study was to investigate the therapeutic effects of natural products like propolis on biochemical and hematologic parameters in carp (Cyprinus carpio, Linnaeus 1758) exposed to arsenic. In this study fish were exposed to 0.01 mg/L arsenic and 10 mg/L propolis for seven days. Our results indicated that triglyceride, urea, total cholesterol, cobalt, ALT (alanine amin...
