- Effects of market public para - dichlorobenzene mothball on the immune function of mice with sub - acute exposure
亚急性染毒对小鼠免疫功能的影响 - Comparative effects of chelating agents on liver toxicity in mice induced by acute exposure to cadmium
五种螯合剂对镉致小鼠脏器脂质过氧化作用的影响 - The degree to which chronic , low - level pollution constitutes a risk to biodiversity is less clear than for acute exposures , but several facts are worth noting
缓慢的低水平的污染对生物多样性构成的威胁不很明显，但是有几个事实值得人们引起注意。 - For the acute exposure duration , there expressed the dose - thresholds and time - thresholds in the effects of cu2 + on the activities of cat , pod and sod in two macrophytes . when the test species were exposed at low dose and for a short period , cu2 + can stimulate activities of antioxidant enzymes . once exceeding the thresholds , cu2 + may inhibit enzymes activities
Cu ~ ( 2 + )低浓度和短时间内对抗氧化酶有诱导作用，超过一定的阈限会产生抑制作用；金鱼藻cat 、 pod 、 sod活性在7天内的最大抑制率与暴露cu ~ ( 2 + )浓度呈显著正相关。 - Responses of antioxidant enzyme in plants to heavy metal and phytoremediation of heavy metal are increasingly concerned . at present , many researches concentrated on the effects of copper on antioxidant enzymes have been conducted at home and abroad , most of which were involved in the acute exposure at high dose
植物抗氧化酶对重金属胁迫的响应以及重金属污染的植物修复已经成为研究的焦点，当前国内外关于铜对植物抗氧化酶影响的研究大多集中于大剂量的急性暴露，对低浓度的慢性效应研究较少。
