Trace metals generally enter into the harbour environment through atmospheric deposition, erosion or due to anthropogenic activities such as release of industrial effluents, domestic and harbour generated sewage and oil spills. The present study was carried out to assess the levels of several trace metals, namely, Hg, Pb, Cd, Cr, Zn, Cu and Ni, in harbour basin water from six selected fisheries harbours along the Southern and Western coasts of Sri Lanka. A total of 54 samples were collected covering the areas around the harbour jetty, harbour entrance and fuel stations during the period of June to December, 2011. The level of total Hg was analyzed by cold vapour atomic absorption spectrometry (CV-AAS) and the other metals by graphite furnace atomic absorption spectrometry (GF-AAS). The trace metal concentrations in fisheries harbour basin water (n=54) varied widely. The mean concentrations ±SD (µg/L) found in the study were Hg <0.16, Pb 0.40±0.61, Cd 0.06±0.17, Cr 0.49±0.80, Zn 13.60±19.1O, Cu 4.68±8.99 and Ni 5.80± 7.98. These values are all well below the limits for estuary and harbour basin water guideline, set by European Union (EU) and the Food and Agriculture Organization (FAO).
