||Environmental risk assessment of difficult substances

||Experience has shown that certain substances have properties that complicate the assessment of exposure and effects. Such substances are often referred to as "difficult substances". The properties or attributes of "difficult substances" have been analysed in relation to the problems arising from the assessment of the effects and/or exposure. This report specifically addresses the risk assessment of substances with the following properties: unstable and highly reactive; poorly water soluble; sorptive; surface active; volatile; naturally occurring, essential and multi-ionic elements. Some substances display more than one of these characteristics and thus, no single property should be considered in isolation. A holistic approach should be applied when conducting a risk assessment for a "difficult substance', taking into account the influence of all properties or attributes.
