污染物质

With the improvement of living quality, air pollution caused by fitment and microorganism became more and more universal and serious.

随着人类物质生活的提高，装修污染和微生物污染的普遍性与严重性已经达到令人震惊的程度。

Guards against the facture and the correlation stipulation based on the air pollution defines, the air pollutant may divide into four big projects, respectively be the gaseity pollutant (including sulfur oxide compound bucket carbon monoxide, nitrogen oxide compound, hydrocarbon, chlorine, gasified hydrogen, fluoride, chlorhydrocarbon and so on), the granular pollutant (including suspended particulate matter, golden bureau coal smoke, black smoke, acid fog, falls dust and so on), two pollutant (refers to pollutant to pass through photochemical reaction in air to have pollution again, including photochemistry fog, photochemistry high oxide compound and so on) and odor matter (including chlorine, hydrogen sulfide, curing methyl, sulfur alcohol type, methyl amines) and so on.

依据空气污染防制法及相关规定所定义，空气污染物可分为四大项目，分别为气状污染物（包括硫氧化物勺一氧化碳、氮氧化物、碳氢化合物、氯气、气化氢、氟化物、氯化烃等）、粒状污染物(包括悬浮微粒、金局煤烟、黑烟、酸雾、落尘等)、二次污染物（指污染物在空气中再经光化学反应而产生之污染，包括光化学雾、光化学性高氧化物等）及恶臭物质(包括氯气、硫化氢、硫化甲基、硫醇类、甲基胺类)等。

The most polluted areas is near Tianjin second gasworks and around sewage river as well as sewage irrigation area. So we can conclude the major sources of pollution is atmospheric deposition and sewage irrigation. Second, It is positive correlation between the heavy-metal contamination and layered silicate minerals, while it is negative correlation between heavy-metals and quartz , feldspar as well as other minerals.

二、重金属污染元素含量与层状硅酸盐矿物含量呈正相关，而与石英长石等矿物含量呈负相关，充分说明污染元素主要赋存在层状硅酸盐矿物中，这与矿物自身的结构有着密切的关系，层状硅酸盐矿物具有很大的层间域，有利于对其他物质的吸附作用。

Based on the data of aerosol chemical compositions obtained at WMO GAW (World Meteorological Organization Global Atmospheric Watch) station in eastern China－Lin'An regional background air pollution monitoring station, two methods (referred as Malm method and Stelson method) that were described by Malm (Malm et al.,1994) and Stelson (Stelson and Seinfeld, 1981) were used to study the mass closure of sampled aerosols.

本文通过在WMO GAW 区域大气本底污染监测站－临安大气本底污染监测站采集的气溶胶样品的化学成分的分析结果，分别用Malm（1994）和Stelson（1981）提出的方法（分别记为Malm方法和Stelson方法）重建气溶胶质量浓度，并与称重获得的质量浓度进行对比，发现虽然Stelson和Malm方法所考虑的物质组成及所使用的化学成分个数并不相同，其计算结果略有差异，但总的来说两种方法都能较好的反映绝大部分的气溶胶质量，在实际应用中可以根据所分析的化学成分数据情况和研究的目的采用不同的质量重建方法。

Both of Eichharnia crassipes and Hosta ventricosa can grow normally in a single nitrogenand phosphorus stress condition, The higher the concentration of nitrogen and phosphorus in waterthe higher the chlorophyll content and dry matter content in plants, it means the growth of plants isgood, This proves that Eichhamia crassipes and Hosta ventricosa has a very strong ability to adaptin a single nitrogen and phosphorus pollution water, they can be used for repairing a singlenitrogen and phosphorus pollution water.

在单氮和单磷胁迫条件下植物都能够正常生长，并且水体中氮、磷浓度越高凤眼莲和紫萼玉簪体内的叶绿素含量及干物质含量就越高，说明两种植物的生长状况就越好，这一点证明两种植物对氮、磷污染的适应能力都很强，可以用于修复单氮和单磷污染水体。

The SARS virus origin which obviously differs from the theory of out space origin and the theory of wildlife origin was theoretically discussed based on principles of pollution evolution ecology,pathogenesis and infectant characteristics of SARS,and some relevant experimental evidence. It emphasizes on the fact that increasingly combined pollution in China provides a substantial basis for virus evolution.

针对当前广为流传的SARS病毒"太空起源说"和"野生动物来源说"两种理论，本文根据污染进化生态学原理和SARS病毒发病传染特征，以有关实验结果为科学依据，阐述了SARS病毒的起源问题，指出：我国当前环境日益严重的复合污染为SARS致病病毒的产生提供了适宜的外部生态条件和物质基础，SARS致病病毒可能起源于多个病毒的基因重组或融合，更可能是一种来自于感冒病毒进化而形成的超级感冒病毒。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
