US EPA: Preliminary Database on Arsenic Species in Target Foods/Groups to Improve Arsenic Risk Characterization
Description
Currently, most of the existing dietary arsenic exposure data reports only a total arsenic value that does not differentiate between inorganic arsenic and arsenobetaine. While total arsenic concentrations can be helpful in identifying target foods which contain a large percentage of the cumulative dietary arsenic exposure, the risk from these exposures cannot be predicted without species specific or chemical form specific information. The development of a preliminary database of the arsenic species in target foods would provide species specific information on a large percentage of the arsenic found in food and would improve exposure source estimates. Thus, the main objective of NERL's dietary arsenic exposure research has focused on developing a preliminary species specific database for target foods including seafood, rice, carrots and apples.
