Soil ingestion by children is an important pathway in assessing public health risks associated with exposure to arsenic-contaminated soils. Soil chemical methods are available to extract various pools of soil arsenic, but their ability to measure bioavailable arsenic from soil ingestion is unknown. Arsenic extracted by five commonly used soil extractants was compared with bioavailable arsenic m...

Emerging data indicate that rice consumption may lead to potentially harmful arsenic exposure. However, few human data are available, and virtually none exist for vulnerable periods such as pregnancy. Here we document a positive association between rice consumption and urinary arsenic excretion, a biomarker of recent arsenic exposure, in 229 pregnant women. At a 6-mo prenatal visit, we collecte...

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...

Large scale use of groundwater for irrigation which is often Arsenic laden, during past two decades, has given rise to the apprehension that this may be resulting in higher Arsenic intake through the food chain. This work was undertaken to determine the trend of average Arsenic exposure of the population in Bangladesh during the period 1990-2010. Based on available data on individual food items...

Background: In the present study, histopathological effects of chronic exposure to sodium arsenate in drinkable water were studied on a quantity of organs of rat. Methods: Rats were divided into two groups, group I served as control group, were main-tained on deionized drinkable water for 2 months, and group II the study group were given 60 g/ml of sodium arsenate in deionized drinkable wa...

Direct measurement of arsenic release requires a good sampling and analysis procedure in order to capture and detect the total amount of metals emitted. The literature is extensively reviewed in order to evaluate the efficiency of full field-scale and laboratory scale techniques for capturing particulate and gaseous emissions of arsenic from the thermo-chemical treatment of different sources of...

Background: Arsenic is a well-documented human carcinogen widely distributed in the environment. Chronic exposure of humans to inorganic arsenicals causes many adverse health effects. The present work was conducted to evaluate the protective effect of Syzygium cumini seed extract (SCE) on arsenic-induced genotoxicity and hepatotoxicity in Wistar albino rats. Methods: Rats were randomly divide...

In order to achieve reliable information on speciation analysis, it is necessary to assess previously the species stability in the sample to analyse. Furthermore, in those cases where the sample treatment for species extraction is time-consuming, an assessment of the species integrity in the extracts is of paramount importance. Thus, the present paper reports total arsenic and arsenic species s...
