Determination of the concentration of alkyllead compounds in fish and water

Abstract

The presence of di‐, tri‐, tetraalkyllead and inorganic lead compounds has been investigated in both fresh‐ and seawater and in fish taken from the North Sea. of 123 fish analysed, 15 (12%) were found to contain measurable alkyllead. Ratios of concentrations in fish + water indicated preferential uptake of alkyllead species relative to inorganic lead. Detection limits for individual compounds were between 0.03–0.44ng Pb g⁻¹ (fish) and 0.1–1.0ng Pb 1⁻¹ (water).
