route and extent (for example, number of organisms) of exposure of organisms present at a site to one or more contaminated media.
Exposure is the contact of a contaminant with any portion of an organism,  system or sub-population. The organism may be exposed by inhalation, ingestion or dermal contact.
Generic ecological investigation levels (EILs) are EILs that are derived without considering any physicochemical properties of soil. When a generic EIL is developed for a contaminant there is a single numerical maximum concentration that is applicable to all Australian soils within each specified land-use.
Generic ecological value is an ecological value associated with a state, region, local area or standardised land-use category.
Hazard is the intrinsic capacity of a chemical, biological, physical or social agent to produce a particular type of adverse health or environmental effect. For example, one hazard associated with dichlorodiphenyltrichloroethane (DDT) is that it can cause the thinning of eggshells of some predatory birds.
Hazardous substance is a chemical that has the capacity to produce adverse effects. For the purposes of this framework, hazardous substance does not include radioactive, physical or biological agents.
High ecological value (see area of ecological significance)
Introduced flora and fauna are biota that are not native to Australia but which are desired to inhabit the site. Such biota may include wildlife, domestic animals, flowering plants, conifers and ferns.
Land use is based on the human purposes or economic activities that are conducted on a piece of land.  This Measure specifies three land-use categories: (1) areas with high ecological value, (2) urban residential and public open space, and (3) commercial and industrial land.
Mixture ecological investigation levels (EILmixture) are EILs that take into account the joint action (toxicity) of mixtures of contaminants. If the EILmixture is not exceeded, then no further investigation is required, whereas, if the EILmixture is exceeded, then further investigation is triggered. If the EILmixture is not exceeded in a Definitive ERA, it is considered that the mixture will not pose an adverse ecological impact, whereas if the EILmixture is exceeded, then it is considered that the mixture will pose an adverse ecological impact.
National Environment Protection Measure (Measure) means a Measure made under section 14(1) of the National Environment Protection Council Act 1994 (Cwlth) and the equivalent provisions of the corresponding Acts of participating states and territories.
Native flora and fauna are biota that would naturally inhabit the site in the absence of the chemical contamination. Such biota may include flowering plants, ferns and terrestrial, subterranean or arboreal fauna.
Octanolwater partition coefficient (Kow) is the ratio of a chemical's solubility in n-octanol and water at equilibrium. This is widely used as a surrogate for the ability of a contaminant to
