摘要
为确定长叶异痣＃对水体镉污染的指示作用，于 2000年 5月、 7月和 8月 3次在太原市清徐县东湖及鱼塘采集长叶异痣＃（成虫）样品（每个样品含 9个同性别的个体）及水样，进行分析研究。结果发现，长叶异痣＃对水体镉具有富集性，可作为水体镉污染的监测生物。同一时间同一采样点所采的此种雄性成虫体内镉含量样本间差异不显著，而随水体镉含量的增加而增加。长叶异痣＃对水体镉污染的程度具有指示作用。
Several Ischnura elegans and surrounding water samples were collected and analyzed for revealing possibility of the organism playing as an indicator for contamination of cadmium on water system. It has been found that Ischnura elegans exhibited a strong ability of accumulation on cadmium in water. Furthermore, there was no statistical difference among the contents of the heavy metal in male adults of Ischnura elegans, collected from same sites and at same time in a lake, suggesting that the organism be an indicator for contamination of Cd on water system.
