摘要: 随着工业化的发展,人类活动对环境造成了严重污染。轮虫是常用于污染物毒性检测的模式生物之一。针对不同类型的污染物,轮虫各生态毒理学指标的敏感性不尽相同。因此,本文归纳了现有的轮虫生态毒理学测试指标,综述了各生态毒理学检测指标对不同污染物的敏感性:轮虫的生命表统计学参数和生理生化指标对重金属污染通常更敏感;在检测持久性有机污染物时,有性繁殖指标通常比无性繁殖指标更敏感;部分研究表明,相较于生命表和种群增长实验,轮虫游泳速度对多种类型的污染物表现出了更高的敏感性,建议纳入轮虫生态毒理学研究中,作为选测指标。这些结果将为后续轮虫生态毒理学研究提供指导。

Abstract: Human activities have severely polluted environments during industrialization. Rotifers are commonly used as model species for ecotoxicological assays. The sensitivities of ecotoxicological indices of rotifers highly depend on different pollutants. We summarized available ecotoxicological indices of rotifers, and reviewed their sensitivity to commonly investigated pollutants. Under the stress of heavy metals, the life-table demographic parameters, physiological and biochemical indices generally show high sensitivity. In response to persistent organic pollutants, sexual indices generally show higher sensitivity than asexual ones. Some studies showed that swimming speed revealed higher sensitivity after exposure to several pollutants compared with life-table demographic and population growth indices. We suggested to consider swimming speed of rotifer as an alternative index for ecotoxicological assays. Overall, this study would provide a guideline for rotifer ecotoxicological studies in the future.
