Abstract
Hair samples were collected randomly from 38 males and 68 females (ages from 2 to 57 years) with no known history of occupational exposure to mercury and were analyzed for total mercury. The mean (+standard deviation) mercury concentration in hair of males was 5.52±5.33 μg/g, while that of females was 4.05±4.40 μg/g. As donors’ ages increase the mercury hair levels appear to decrease, although a significant coorelation was not found (r =0.44). A 21% of the studied population exhibited hair mercury levels above the 6 μg/g Swedish limit. The mean hair mercury levels showed an increase with increasing fish intake frequency.
