title: Baseline metal concentration in the Asian periwinkle Littorina brevicula employed as a biomonitor to assess metal pollution in Korean coastal water.
abstract: Concentrations of Al, Fe, Mn, Cu, Zn, V, Ni, Co, Cr, Cd and Pb in the Asian periwinkle Littorina brevicula were determined from 39 sampling locations along the whole Korean coast. Metal concentrations in the periwinkle varied highly with sampling stations, but the variations could be well explained by the body size after eliminating the data exceeding the 'High' criteria. Among the stations exceeding the 'High' criteria corresponding to mean plus one standard deviation of the logarithms of the individual site mean, some stations exhibited values higher than expected from the relationship between metal body burden and body size, indicating that these locations were polluted with metals. However, several 'High' stations followed the trends of the curve, suggesting that they resulted from the effect of their small body size, not from environmental contamination. Periwinkles of similar body sizes exhibited same range of metal concentrations in their body, independent of geographical position.
