测定了1977年至1990年间在法国大西洋海岸搁浅的36只海豚的肌肉、肝脏和肾脏中的重金属浓度（总汞、钛、铬、铜、锌、镉和铅）：29只普通海豚Delphinus delphis、活瓶鼻海豚Tursiops truncatus和两只条纹海豚Stenella coeruleoalba。肝脏中总汞浓度随年龄增长而增加，而甲基汞相对浓度则下降，反映出存在缓慢的去甲基化过程。在较低程度上，在肾脏和肌肉中观察到类似的模式。没有发现与年龄相关的其他重金属的增加，虽然最高水平的镉和铬总是发现在成年人。在1977-1980年和1984-1990年这两个时期之间，没有发现污染方面的差别。(C)1998 Elsevier Science B.

Heavy metal concentrations (total and organic Hg, Ti, Cr, Cu, Zn, Cd and Pb) were determined in the muscle, liver and kidney of 36 dolphins stranded on the French Atlantic coast between 1977 and 1990: 29 common dolphins Delphinus delphis, live bottlenose dolphins Tursiops truncatus and two striped dolphins Stenella coeruleoalba. Total Hg concentration in the liver increased with age, while relative methylmercury concentration decreased, reflecting the existence of a slow demethylation process. To a lower extent, a similar pattern was observed in the kidney and muscle. No age-related increase was found for other heavy metals, although the highest levels for Cd and Cr were always found in adults. No difference in contamination could be detected between the 1977-1980 and 1984-1990 periods. (C) 1998 Elsevier Science B.V. All rights reserved.
