This page has been designed to allow users to quickly search for a stressor, toxicant or contaminant and to navigate to the set of guidelines that they require for it. There are two options:
    1. Choose a name and an Environmental Value List;
    2. Simply select an Environmental Value List, by-passing the name nomination
In both cases the user will be required to nominate a Region and Ecosystem Type for ecological protection.

For Physical & Chemical Stressors separate guidelines are available for four major regions in Australia:
    South-East Australia - includes all of NSW, ACT, Victoria and Tasmania, and non-tropical areas of Queensland.
    Tropical Australia- Includes areas in QLD, NT and WA north of the tropic of Capricorn.
    South-West Australia - includes non-tropical areas of WA.
    South-Central Australia - includes all of SA and non-tropical areas of NT.
    New Zealand

In each Region separate guidelines are available for three groups of ecosystems:

Regions

Ecosystems

1. Upland and Lowland Rivers

2. Lakes, Reservoirs and Wetlands;

3. Estuaries and Marine

You must select a Region and Ecosystem to proceed. Although most guidelines apply nationally, this nomination will ensure that the correct Physical & Chemical stressor guideline values are displayed for comparisons.
