Abstract

The major potential problems from a landfill are biogas and leachate generated from the wastes deposited. These factors can also exert harmful effects on the growth of vegetation and influence the diversity and distribution of soil animals, either directly or indirectly. This paper describes investigations undertaken at the completed Gin Drinkers' Bay landfill, Hong Kong. The absence of plant cover at the site limited the occurrence of some common soil animals such has Diplopoda, Hemiptera, Isopoda and Isoptera. This was possibly due to the shortage of plants as shelter and the lack of organic matter as food. One area (site H), with a high level of landfill gas in the soil zone, had a lower diversity of soil animals than another area (site L) with a lower level of landfill gas. Some edaphic factors such as moisture content and concentrations of K, Na and Mg in the "contaminated" site H may also have resulted in lower numbers of species and individuals.
