Due to the lack of New Zealand-specific ecotoxicity
data, environmental risk assessments in New Zealand are currently based on
toxicity data obtained largely from overseas test organisms.
Often this data is inappropriate for the New
The ecotoxicity values presented in this section have been derived from New
Zealand-specific standardised tests. These tests have been adapted from international
guidelines and are conducted on a range of soil fauna and flora, and freshwater aquatic
vertebrates and invertebrates. The tests used
measurement end points (such as growth, survival and reproduction) that are
directly applicable to risk assessment purposes.
Test organisms were selected not only on their suitability for use in standard testing protocols,
but also for their widespread occurrence and ecological importance in New
