Discharge of disinfected wastewater in recipient aquatic systems: fate of allochthonous bacterial and autochthonous protozoa populations.

在本试验条件下得到了标准消毒条件下（温度20°C，消毒时间30min，pH值为7.0）有效氯投量为10mg/L和50mg/L时，峰点前加氯消毒后污水的急性毒性增量（以Zn2+浓度表示）预测公式：y=0.7179x-0.0195，y=2.915x+1.0125（其中y为消毒后污水的急性毒性增量，x为污水的UV254与NH3-N的比值）。

These toxic data(TC50,SDH and LDH) were used as dependent variable and 10 topological indices of 25 aminobenzene derivatives were used as independent variable.QSAR was analyzed with multiple stepwise linear regression.The results indicated that there is different toxicity with different structure of compounds.

内容摘要以大鼠游离肝细胞半数中毒浓度(TC50)和细胞逸出酶为观察指标，研究了25种苯胺类化合物的肝细胞毒性，并利用这些毒性效应数据为因变量，以这些化合物的10种拓扑学指数为自变量，利用多元逐步回归统计分析方法进行了定量结构-活性关系的深入探讨。

Aristolochic acid is the main component of Aristolochia plants. It is a mixture of aristolochic acid Ⅰ and aristolochic acid Ⅱ. It has been proved by several researches that AA has nephrotoxicity and tumor toxicity. However, the pharmacokinetics of AA is still limited.

马兜铃酸是马兜铃科植物的主成分，为马兜铃酸Ⅰ及马兜铃Ⅱ所构成的混合物，研究指出AA具有肾毒性及肿瘤毒性，但对於AA在药物动力学方面的研究报告则是相当有限。

It is similar in structure to αandβ-Asarone that are genetoxic to rat hepatocytes. Carpacin''s isomer, myristicin is not genetoxic to rat hepatocytes and can induce glutathion S-transferase activity that is reported to have effect in rat hepatocytes.

其类似物α与β-Asarone对鼠肝细胞具有基因毒性及其异构物myristicin对鼠肝细胞并无基因毒性，且可诱发出glutathion S-transferase等解毒酵素的活性。

Dose-dependent toxic effects in primary cultured astroglia could be induced by exposed to iAsⅢ or iAsⅤ within the concentrations of 25～100 μmol/L or 100～500 μmol/L, respectively.

接触最少25 μmol/L的3价无机砷或100 μmol/L的5价无机砷对星型胶质细胞可产生明显的毒性损伤作用。3价无机砷的毒性明显大于5价无机砷。

The acute and chronic toxicities of benzidine to Daphnia magna were studied.

研究了联苯胺对大型溞的急性毒性和慢性毒性。

Results:The results showed that the intermediates para benzoquinone had a higher toxicity, while the toxicity of the other intermediate products was much lower than that of chlorobenzene.

结果：除了降解中间产物对苯醌毒性比氯苯大得多以外，其他降解中间产物毒性均比氯苯低，未开环的降解中间产物对氯苯酚？

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
