An overview of trace metal pollution in the coastal waters of Hong Kong

摘要: The state of metal pollution in Hong Kong's coastal waters has been assessed by measuring levels in: (i) the water column; (ii) sediments and (iii) organisms, i.e. biomonitors. Current literature is reviewed. Data from sediment analysis have shown that most severe urban areas Victoria Harbour, Tolo Deep Bay Northwestern waters. Bottom typhoon shelters are particularly heavily polluted with, for example, Cu Kowloon reaching 5300 mg·kg−1 1995. Since 1987, generally either stabilized or fallen Harbour but increased Inner Many biomonitors used to study Kong, popular which barnacles, mussels (in particular Perna viridis) algae Ulva lactuca). Biomonitoring studies recorded high late nineteen seventies early eighties, with increasing semi-enclosed through eighties nineties. In a recent using Ag, As, Cd, Cu, Hg, Pb Zn were be greatly reduced as compared those 1986 1989, respectively. Levels Kong may lowered last 10 years.
