有机物

However, the surplus residual chlorine can affect people's taste and smell, destroy the quality of water. Moreover, in the process of disinfection, chlorine can react with organic matter and produce a series of hydrochloric ether such as chloroform, bromoform, bromodichloromethane, chlorodibromomethane and so on, these matters can cause to some extent cancer to human body.

但是，水中过量的余氯会影响水的口感和气味，破坏水的品质；此外，在消毒过程中，氯与水中残余的有机物产生化学作用，生成一系列氯代烃如三氯甲烷、溴仿、溴二氯甲烷、氯二溴甲烷等，这些物质会对人体产生一定程度的致癌作用；对于以自然水源作为生活用水来源的城市必然要对水加氯消毒后才可使用。

Methods: The twelve volatile halogenated hydrocarbons (1, 1-dichloroethene, dicloromethane, trans-1, 2-dichloroethene, cis-1, 2-dichloroethene, chloroform-1, 1, 1-trichloroethane-1, 2-dichloroethane, tetrachloromethane, bromodichloromethane, dibromochloromethane, tetrachloroentene and bromoform) in drinking water were determined by headspace capillary gas chromatography.

采用顶空毛细管柱气相色谱法测定饮用水中1，1-二氯乙烯、二氯甲烷、反－1，2-二氯乙烯、顺－1，2-二氯乙烯、三氯甲烷、1，1，1-三氯乙烷、1，2-二氯乙烷、四氯化碳、一溴二氯甲烷、二溴一氯甲烷、四氯乙烯及三溴甲烷等12种挥发性卤代有机物。

Thirdly, Lower-grade plants such as lichen, bryozoan etc. begin to grow. Along with the accumulation of living beings is going more and more, the amount of organic matter in the parent material forming soil is going more and more, Then higher-grade plants gradually replace lower-grade plants, and through strong and extensive root system, the dispersive and soluble nutrition can be concentrated. After the death of organisms, and through decomposition of microbes, one part of the remains of the organisms becomes nutrients for plants, and another part of the remains turns into humus.

第三步，地衣、苔藓类低等植物开始生长，随着生物的积累作用越来越大，成土母质中的有机物数量不断增加，最后高等植物逐渐取代了低等植物，通过强大的根系把分散的可溶性养分集中起来，等到这些生物死亡之后，它们的残体经过微生物的分解作用，一部分成为后来植物所需的养分，另一部分变成了腐殖质。
