  2. Photo of bio - remediation of anoxic sediment being carried out in the sam ka tsuen typhoon shelter in 2004

    三家村避風塘於2004年採用生化方法處理缺氧沉積物圖片
  3. Bio - remediation can be achieved in different ways, but in the case of the shing mun river, it involved injecting calcium nitrate into the sediment, thus converting anoxic pollutants into odourless gases such as nitrogen or carbon dioxide, and in the process removing offensive odours

    生化處理可以多種形式進行，以城門河為例，處理程序是將硝酸鈣注入沉積物內，使缺氧的污染物轉化為氮或二氧化碳等無臭氣體，從而消減臭味。
  4. Heavy metals and organic contaminants are very persistent in marine sediment. sediments in victoria harbour have an elevated organic content and are highly anoxic with low electrochemical potential due to sewage, as well as being contaminated with heavy metals

    海洋沉積物內的重金屬及有機污染物一般均難以降解而維持較久，長期以來污水排放使維多利亞港海床沉積物的有機物含量偏高，因而導致沉積物高度缺氧和電化學勢下降，重金屬污染也較嚴重。
  5. Phosphate deposits are distributed along the margin, platform and basin in the west yangtze area. the analysis methods include the paleogeography, petrology, organic geochemistry, geochemistry. the conclusions are drawn that the source of phosphate deposits distributed along the margin originate from the weathering production of continent, while phosphate deposits along the platform and basin gain phosphorus through hot spring on the buttom of the sea floor, which is brought to the sedimentary environment by rising sea - fluid, then accumulated by the organism and microorganism, meanwhile, basin phosphorite keep relatively higher organic carbon content
