This baseline assessment of contaminants in the sediments of the Swan and Canning estuaries was a snapshot study conducted in November 2007 as part of the Non-Nutrient Contaminants Program.
Twenty sites were assessed for metals, organochlorine pesticides and polycyclic aromatic hydrocarbons bound to the surficial sediments (top 3cm). Both sites and contaminants were selected based on information generated from earlier components of the Non-Nutrient Contaminants Program and other local studies.
