The Greater Wellington Regional Council (GWRC) engaged NIWA to prepare and process estuarine sediment samples collected from Porirua Harbour in late 2010 and manage the analyses of both organic and metal contaminants for comparison with ANZECC sediment quality guidelines. Metal contaminants were analysed by Hill Laboratories and reported elsewhere. NIWA provided analytical data for organochlorine pesticides (OCs), polycyclic aromatic hydrocarbons (PAHs) and particle size distributions (0-300 μm). This report describes methodology and presents results [including quality assurance (QA) data] for the analyses of OCs, PAHs and particle size distributions for estuarine sediment samples collected from Porirua Harbour in 2010.

This report briefly describes methodology and presents results for the analyses of contaminants and particle size distributions for catchpit sediment samples. TPH, TOC and heavy metal results were produced by Hill Laboratories. PAH and chemical marker compound results were produced by NIWA.

This report briefly describes methodology and presents results [including quality assurance (QA) data] for the analyses of Wellington Harbour marine sediments for sediment contaminants. Results reported for total organic carbon (TOC), total petroleum hydrocarbons (TPH), organochlorine pesticides, Polycyclic aromatic hydrocarbons (PAH), PAH chemical markers, heavy metals and sediment particle size distributions. TPH, TOC and heavy metal results were produced by Hill Laboratories. Organochlorine pesticides, PAH and PAH chemical marker compound results were produced by NIWA.

Samples of oysters from multiple sites in the Manukau Harbour and transplanted mussels from multiple sites in Auckland estuaries and Waitemata Harbour were analysed for %lipid, organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs). Analytical data for oysters and mussels were presented along with analytical procedures, methods and a quality assurance summary. The report includes lipid-normalised data sets of selected contaminants for comparison with earlier data sets.
