Summary
Shellfish results: Ivey Bay exceeded shellfish consumption guide levels; Paremata station and Horokiri Stream mouth were marginal. Porirua Stream/South Mungavin Point exceeded levels in heavy metals, organochlorines and PAHs (formed from incomplete combustion of organic material) in the sediment. Results suggest urban impacts from Porirua area. Organochlorine levels exceeded lower guideline level around Pauatahanui Stream mouth area suggesting that rural impacts from the catchment may impact on fauna in nearby sediments to stream mouth.
