This review attempts to put into perspective the effects of past and present discharge of heavy metals into the New Zealand aquatic environment. The sources of heavy metals are briefly described and concentrations of metals that have been found for geothermal, precipitation, weathering and erosion, agricultural and urban land use, sewage, refuse tip, and industrial inputs are summarised. A national perspective of natural background levels of metals in water, sediments and biota is attempted, drawing on overseas data where New Zealand information is lacking. Concentrations of metals found in the New Zealand aquatic environment are summarised on a regional basis. Overseas metal criteria and standards for the protection of human health, aquatic life, stock and irrigation are described and compared. To aid in the understanding of the information presented in this review, there are chapters on the biology and chemistry of heavy metals in the aquatic environment, and sampling and analytical methods. Recommendations are made to improve management of heavy metal discharges. Areas for further study are also suggested
