[1]  In cases where the LOEC and/or EC30 data are not available but other measures of toxicity are then the latter will be divided by conversion factors to obtain the former (refer to Glossary, Section 2.4.2.1 and Table 8 for further details).
[2] Protection is provided in terms of the percentage of species and soil microbial processes because the method used to derive EILs is a species sensitivity distribution method.
[3] This occurs because as exposure to a toxicant increases, the external ambient concentration needed to cause a toxic effect decreases.
[4] The H can also be expressed on a mass basis (e.g. mg/kg).
[5] The Australasian Ecotoxicology Database is in the process of being placed on the CSIRO website. It should be available in 2011.
[6] This is done by comparing values predicted by the non-Australian normalisation relationships to Australian toxicity data.
[7] The geometric mean is analogous to the normal arithmetic mean except that the values are logged before summing and being divided by the number of data points. The value is then anti-logged to provide the geometric mean. The formula for this is
Geometric mean = anti-log [(logA + log B +…..logN)/n]     (equation 13)
In determining the geometric mean the
