Contaminants in Global Harbour Sediments
Harbours in all parts of the globe have sediments contaminated with heavy metals and organic pollutants.
Sources include: shipping activities (including anti-fouling paints, dry dock, loading and bunkering operations, and ship repair and building), industry (e.g. pyrogenic processes, spills and leaks), urbanisation (e.g. sewage outfall, urban run-off, stormwater inputs) and agricultural waste.
WG1 is investigating the distribution of contaminant enrichment in harbour sediments, the risk to benthic communities that these contaminants present and, where possible, the relationship between enrichment, risk and infaunal diversity.
Data from Australia (Sydney, Darwin and Hobart), New Zealand (Auckland), Hong Kong, Italy (Ravenna) and Spain (Vigo) will be mapped using existing data sets in ArcGIS.
