We examined the concentrations of arsenic, cadmium, chromium, lead, manganese, mercury, and selenium in the eggs, leg muscle, and apodeme (carapace musculature) in horseshoe crabs ( Limulus polyphemus) from eight places on the New Jersey and Delaware sides of Delaware Bay to determine whether there were locational differences. Although there were locational differences, the differences were not great. Further, contaminant levels were generally low. The levels of contaminants found in horseshoe crabs were well below those known to cause adverse effects in the crabs themselves or in organisms that consume them or their eggs. Contaminant levels have generally declined in the eggs of horseshoe crabs from 1993 to 2001, suggesting that contaminants are not likely to be a problem for secondary consumers or a cause of their decline.
我们检测了来自特拉华湾新泽西州和特拉华州一侧八个地点的鲎（美洲鲎）的卵、腿部肌肉和肉茎（头胸甲肌肉组织）中砷、镉、铬、铅、锰、汞和硒的浓度，以确定是否存在位置差异。尽管存在位置差异，但差异不大。此外，污染物水平总体较低。在鲎体内发现的污染物水平远低于已知会对鲎本身或食用它们或其卵的生物造成不利影响的水平。从1993年到2001年，鲎卵中的污染物水平总体呈下降趋势，这表明污染物不太可能成为二级消费者面临的问题或导致其数量下降的原因。
