Paragraph 12 Step 3: Exposure characterisationF1
(1)
The likelihood or probability of each identified potential adverse effect occurring must be evaluated to provide, where possible, a quantitative assessment of the exposure as a relative measure of probability, or otherwise a qualitative assessment of the exposure. The characteristics of the receiving environment(s) and the scope of the application must be taken into consideration.
(2)
Where the evaluation is expressed in qualitative terms, a categorical description (‘high’, ‘moderate’, ‘low’ or ‘negligible’) of the exposure must be used and an explanation of the scale of effect represented by each category must be provided.
