The epd s long - term monitoring data indicates that the electrochemical potential of the sediment at sam ka tsuen typhoon shelter which reflects its oxygen content was substantially raised became less negative as a result of the bio - remediation programme , and the total sulphide level hydrogen sulphide gas , the source of the bad odour was significantly reduced 環保署的長期監測數據顯示，三家村避風塘的沉積物經生化處理后，其電化學勢反映水含氧量大幅提高負數值降低，而總硫化物水平導致臭味的硫化氫氣體來源則明顯下降。 |

In 2005 , 61 physical and chemical parameters were measured and analysed in sediments . these included particle size , electrochemical potential as highly anoxic sediment with negative potential is related to organic pollution , chemical oxygen demand which indicates organic pollutants , total sulphide inorganic constituents , source of the unpleasant - smelling gas hydrogen sulphide , 15 metals and metalloids aluminium , arsenic , barium , boron , cadmium , chromium , copper , iron , lead , manganese , mercury , nickel , silver , vanadium and zinc , and trace toxic organics pahs and pcbs - 16 compounds and 18 congeners respectively 2005年，沉積物監測包括分析61種物理及化學參數，其中有粒子大小電化學勢有機污染促使沉積物缺氧，而讓電化學勢呈負數值化學需氧量顯示有機污染程度總硫化物無機物，是造成難聞氣體硫化氫的主因15種金屬及準金屬鋁砷鋇硼鎘鉻銅鐵鉛錳汞鎳銀釩及鋅和痕量毒性有機物多環芳烴及多氯聯苯分別為16種復合物及18種同質物。 |

They are sulphide and free hydrogen sulphide . from 1989 , selected monitoring stations also monitored e . coli and faecal coliforms , which indicate faecal contamination from domestic sewage and animal waste . these two bacterial parameters were extended to all stations from 1999 自1989年開始，部分河溪監測站開始監測大腸桿菌及糞大腸菌群以顯示住宅污水及動物糞便所造成的水污染其后在1999年起，所有監測站均測試此兩項細菌參數。 |

One of the most noticeable problems associated with water pollution is the bad smell of polluted water , an odour problem occurring when hydrogen sulphide gas is released from sediment that is rich in organic matter and low in oxygen 政府多年來一直致力解決避風塘水質污染問題，其中較易為市民察覺的一項就是臭味問題。臭味的成因是海床沉積物中的有機物質過高和含氧量低，因而形成硫化氫這類難聞的氣體。 |

In the first stage , anaerobic hydrogen depolarization is predominant and produced iron oxide corrosion product layer ; in the second stage , due to bio - produced hydrogen sulphide , iron oxide was biomineralized and translated iron sulphide 初期是厭氧條件下的氫去極化，生成氧化物產物層；然后在srb代謝產生的h2s作用下，發生氧化物到硫化物的轉變。 |
