PAHs ratios are used to identify the source of PAHs, the result showed that the major source of 16 PAHs in Urumqi Xinshi district was coal-bustion and vehicle discharges . Mercury in TSP samples were digested by aqua regia and analyzed by AFS analyzer .The results showed that : the concentration of mercury was 0.869-1.91 ng m-3.Compared with other cities in the rest of the world , the concentration of mercury was very high. The concentration of mercury in heating season was lower than that in no-heating season.

对大气颗粒物样品中的汞，采用王水于特弗龙消解罐中加热消解的方法进行处理，稀酸定容后采用原子荧光光谱法对样品中的汞进行测定，测定结果为。869-1.91 ng m-3，与国外城市相比较高；实验测得非采暖期乌鲁木齐大气颗粒物汞浓度的均值高于采暖期颗粒物中的汞浓度，其原因可能是由于随着非采暖期温的升高，长期积累在土壤、水体环境中的汞向大气中释放，附着在颗粒物上，过了燃煤的影响。

In order to observe the effects of mercuric chloride to physiological and biochemical indexes of blood at low doses in SD rats, 24 SD rats were separated into control group, low dose group of mercury (50 mg/L), middle dose group of mercury (100 mg/L), high dose group of mercury (200 mg/L), which were given in the drinking water.

Mercury chloride have DNA amage in vero cells exposed to low dose of mercury chloride in short term, zinc sulfate and sodium selenite which are used solely and together can reduce the DNA mage of mercury chloride in vero cells.

这对进一步探索氯化汞肾脏毒性机制和防护具有一定的意义。

Methods The mercury in urine, which is the total amount of inorganic mercury in urine, including those produced from organic mercury after treated by potassium bromate and potassium bromide, is determined by atomic absorption spectrophotometer after reduction into mercury atom with sodium borohydride.

方法］尿样中汞（尿中无机汞和经溴酸钾－溴化钾处理尿中有机汞生成的无机汞之和）以硼氢化钠还原生成汞原子蒸气，用原子吸收光谱仪测定其汞的含量。

The high-pressure mercury vapor lamp according to the invention is remarkable in that germanium and oxygen are added in small quantities to the mercury and/or the mercury halides.

根据本发明的高压汞蒸气灯的显著之处在于给汞和/或卤化汞添加少量的锗和氧。

The results show that the contents and distributions of mercury in Jiaozhou Bay were affected by coastal runoff and phytoplankton bloom The linear relationship between organic mercurv and the COD and the exponential relationship between inorganic mercury and chl-a implied that marine phytoplankton could absorpt mercury in sea water and played an important role in controling the speciations of mercury in the Bay.

测定结果表明，胶州湾中汞含量和分布规律与浮游植物的盛衰和陆地迳流有关。有机汞和COD之间存在着线性关系，溶解无机汞含量随叶绿素a含量增加呈指数下降，表明浮游植物对汞的富集及其在海水中形态的转化起着十分重要的作用。

Mercury contents in the polluted rivers and soils are usually high when it is high in the goldmine wastewater and tailings debris. Because the environment polluted by mercury is very difficult to recover and some biology can highly enrich mercury in their bodies, it is necessary to strengthen manage the tailings debris and ban amalgamation process and the low technique individual gold digger.

金矿废水废渣中汞含量高，则受其污染的河流和土壤中汞含量也相应较高，由于环境汞污染的永久性和难修复性，以及某些生物对环境中的汞有富集放大作用，因此除了加强对已产生的尾矿渣的管理外，还应该坚决取缔混汞法和技术水平低下的个体采金行为。

The invention relates to a method for cleaning mercury and nitrogen oxide in fire coal smoke gas, employing specific chemical matter as additive to be added into high-heat smoke gas in furnace, said chemical matter selectively reducing nitrogen oxide and oxiding mercury into bivalent mercury.

本发明涉及一种燃煤烟气中单质汞与氮氧化物的同时净化方法，采用特定的化学物质作为添加物加到锅炉的高温烟气中，通过该化学物质对烟气中的氮氧化物进行选择性还原，同时将单质汞氧化成二价汞。
