Lead concentrations were measured in eggs, prefledgings and adult laughing gulls collected near Galveston, Texas. No lead was found in eggs. Prefledgling and adult birds had lead ranging from zero to 16 mug/g wet tissue. Liver had the greatest lead concentrations followed by brain, heart and skeletal muscle. There were no significant differences in lead concentrations between fledglings and adults or between males and females.
在得克萨斯州加尔维斯顿附近收集的褐笑鸥的蛋、离巢前雏鸟和成年鸟中测量了铅浓度。在蛋中未发现铅。离巢前雏鸟和成年鸟的铅含量范围为每克湿组织0至16微克。肝脏中的铅浓度最高,其次是大脑、心脏和骨骼肌。离巢前雏鸟和成年鸟之间或雄性和雌性之间的铅浓度没有显著差异。
