Association of beer consumption with arsenic concentration in urine: a result from a cross-sectional study of the general Japanese population

The first aim of this study was to evaluate the association between time spent living near a contaminated area and concentration of arsenic (As) compounds in the urine among study subjects.

The median value of the sum of inorganic As (iAs) and total As (tAs) compounds was used for us to divide into two groups, such as the high and low iAs and high and low tAs groups. We analyzed data separately in two-age strata of age group A (the subjects
