Factors to be considered for assessing the groundwater surface water air exposure pathways are. The volume and physical and chemical properties of the secondary material including its potential for migration off the pad. The potential for human or environmental exposure to hazardous constituents migrating from the pad via each exposure pathway and the possibility and extent of harm to.
Characterization factors also are commonly referred to as equivalency factors. Characterization provides a way to directly compare the LCI results within each impact category. In other words characterization factors translate different inventory inputs into directly comparable impact indicators.
For example characterization would provide an estimate of the relative terrestrial toxicity. The presence of toxic substances mainly AOX and dioxins in effluents from pulp bleaching has been reduced by 95 down to a level of 01 KgAOXt-1 of pulp since 1990 mainly thanks to the replacement of chlorine gas by elemental-chlorine-free and total-chlorine-free chemicals in bleaching processes Aspapel 2011.
