利用室内微宇宙系统研究三唑酮对淡水浮游动物群落的影响
Study on the Effect of Triadimefon on Freshwater Zooplankton Community Using Indoor Microcosm System
-
摘要: 三唑酮广泛用于水稻田，常在水环境中残留。为研究三唑酮在环境暴露下的生态风险，通过室内标准微宇宙试验系统检验三唑酮对浮游动物的效应。结果表明，在试验初期，三唑酮对部分浮游动物种群表现出抑制作用：对枝角类生物有明显的抑制作用，对桡足类则展现出轻微的抑制作用。8种生物及桡足类无节幼虫对三唑酮的敏感性依次为：盘肠溞>平突船卵溞>隆线溞>萼花臂尾轮虫>低额溞≥锯缘真剑水蚤≥无节幼虫≥单趾轮虫≥中华薄壳介。在整个试验周期内，三唑酮对浮游动物群落的最大无作用剂量（NOECcommunity）>2 078.88 μg·L-1。在水稻种植季节，三唑酮在沟渠水最大残留浓度为12.00 μg·L-1，低于本研究中三唑酮的NOECcommunity。由此可以推测，三唑酮对浮游动物群落的风险很小。Abstract: Triazolone is widely used in rice fields and it often remains in the aquatic environment. In order to study the ecological risks caused by triadimefon exposure, the effect of triadimefon on zooplankton was examined by an indoor standard microcosm test system. The results indicated that triadimefon inhibited several zooplankton populations at the beginning of the experiment, in which Cladocerans was inhibited significantly, and Copepods was slightly inhibited. The sensitive order of eight organisms and larvae of Copepods to triadimefon was as follows: Chydorus sp.>Scapholeberis mucronata>Daphnia carinata>Brachionus calyciflorus>Simocephalus vetulus≥Eucyclops serrulatus≥naupiar larva≥Monostyla sp.≥Dolerocypris sinensis. The no observed effect concentration (NOECcommunity) imposed by traidmefon on the zooplankton community was higher than 2 078.88 μg·L-1. During the rice planting period, the maximum residual concentration of triadimefon was 12.00 μg·L-1 in the water, which is lower than the NOECcommunity of triadimefon in this study. It could be speculated that triadimefon exhibited low risk to zooplankton community.
