| 摘 要： | 以葫芦岛锌厂周围草地中的蜘蛛为研究对象,研究了汞在蜘蛛体内的含量及分布规律。结果表明,蜘蛛体内汞含量范围为6.72～185.01ng·g^-1,平均60.19ng·g^-1,远高于对照地区蜘蛛。不同采样点蜘蛛体内汞含量之间存在较大差异,距离锌厂远近对蜘蛛汞含量影响明显。蜘蛛体内总汞含量、头胸部及腹部汞含量分别同蜘蛛体重、对应器官重量之间呈显著负相关关系。蜘蛛不同器官中汞含量差异显著,表现出头胸部〉足〉腹部的规律。但是同其他昆虫相比,蜘蛛对汞的富集程度并不明显。

| Abstract: | Compared with the aquatic ecosystems, few are available on heavy metal transferring and accumulating through the terrestrial food chains. A great deal of mercury-contained waste are brought in the course of metals smelting process and would cause mercury contents rise in the soil, water, and air around the smeltery, but mercury contents in terrestrial biota, especially in insects, are deficiency to be discussed. Spiders are common and representative predators in summer grasslands. In order to study the distribution and accumulation characteristics of mercury in spiders, total mercury contents were analyzed with cold atomic absorption technique using samples collected around the zinc smeltery in Huludao City. Results indicated that mercury contents in spiders on wet basis were 6.72-185.01 ng.g^-1 with the average values of 60.19 ng.g^-1, which were much higher than those in the contrast areas. Mercury contents in spiders of different sites varied with and were remarkably affected by the distances to the zinc smeltery. Mercury contents in the whole body, the cephalthorax and the abdomen were negatively correlated with their corresponding weights, respectively. It showed that the biomass increasing would reduce total mercury contents in spiders. Mercury contents in parts of spiders significantly differed and ordered as the cephalothorax〉the legs〉abdomen. But spiders did not show higher mercury accumulation abilities than other insects. |
