consumption per day in [micro]g (As/day) is calculated as the amount of food or beverage ingested for a particular consumption pattern (e.
To gain insight into the link between arsenic
exposure and changes in blood pressure, researchers based at the University of Chicago, Columbia University, and New York Langone Medical Center analyzed data for 10,853 individuals participating in the Health Effects of Arsenic
Longitudinal Study (HEALS), a long-term prospective cohort study.
Human acquaintance with arsenic
goes back more than 2,000 years, when the ancient Greek, Chinese and Egyptian civilizations independently identified two minerals that became known as orpiment and realgar.
Setting limits for arsenic
in foods, like juice and rice, is important to help reduce exposure and better protect public health.
Diet is a large source of both inorganic and organic arsenic
for typical individuals.
The consumer group tested more than 200 rice products and found varying levels of arsenic
, including some that it termed "significant.
The magazine refers to the amount of arsenic
discovered as "worrisome levels of arsenic
Cigarette smoking is pervasive all over the world, and arsenic
exposure on top of it creates a major public health problem," said Habibul Ahsan, MD, MMedSc, Professor and Director of the Center for Cancer Epidemiology and Prevention at the University of Chicago Medical Center and senior author of the study.
While independent studies have found arsenic
residues in grocery store and fast food chicken, higher concentrations of inorganic arsenic
, the most toxic form of arsenic
, have been measured in the soil and water in regions where broiler chicken production is high, and where chicken litter is spread on fields as fertilizer.
The difference in arsenic
toxicity is mainly because of geological factors.
This survey included two different areas which are highly exposed to arsenic
through drinking water and a control area (non-exposed to arsenic
) to determine any association between chronic arsenic
exposure and adverse pregnancy outcomes.
In the study, Kevin Francesconi and colleagues found that some people eliminate more than 90 percent of the arsenic
consumed in the diet while others store arsenic
in their bodies, where it can have harmful effects.
