Ionic alkylleads in herring gulls from the Great Lakes region
Herring gull (Larus argentatus) tissues, collected from various breeding colonies in the Great Lakes, were examined to determine alkyllead levels and possible alkyllead sources into the Great Lakes region. Ionic trialkyl- and dialkyllead species (R/sub 3/Pb/sup +/, R/sub 2/Pb/sup 2 +/; R = Me, Et) were quantitated by gas chromatography-atomic absorption spectrometry. The extraction procedure was tested at trace levels (3-4 ppb as Pb) with four domestic chicken (Gallus domesticus) tissues. Trimethyllead was found in two avian species and all examined tissues. Methyllead levels frequently exceeded ethyllead levels with no direct automotive source. Correlation between alkyllead levels in herring gull tissue and lake sediment lead levels suggests possible methylation but not ethylation of inorganic lead. The methyllead concentration trend in gull tissues. Lake Ontario > Lake Huron approx. = Lake Erie > Lake Superior, was opposite to the ethyllead concentration trend, Lake Superior > Lake Huron > Lake Erie approx. = Lake Ontario. 40 references, 3 figures, 7 tables.
