摘　　要：为确定长叶异痣对水体铅污染的指示作用,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个个体)及水样,进行分析研究。结果发现,长叶异痣对水体铅具有富集性,可作为水体铅污染的监测生物。但为了保护蜻蜓,使雌性产卵不受影响,采样时应以雄性为宜。同一时间同一采样点所采的长叶异痣雄性成虫体内铅含量样本间差异不显著,并且此种昆虫雄性成虫体内铅含量有随水体铅含量的增加而增加的趋势,对水体铅的污染程度具有指示作用。In order to assess indicating function of Ischnura elegans in lead polluted water, we collected samples (each sample contains 9 individuals male & female adults) three times from the East Lake of Qingxu county and a fish-pond in Taiyuan in May?July & August 2001. The results showed that the specieswere very susceptible to lead in water, suggesting that the organism be used asan indicator organism for lead in water. No significant difference was found for male adults from same time and location. The contents of lead in male increased with the increase of the contents in water as well. It maybe concluded that male could be used as an indicator organism in determination of the degree of leadpolluted water.
