7.4.3 Toxicological effects<br />

The effects <strong>of</strong> longer transports in the recycling cases result in altered rankings compared to<br />

the base and medium transports scenario for some toxicological assessments. For ecotoxicological<br />

effects using the EDIP method this is the case for the newspaper fraction, where<br />

the increased transport distances leads to a fall in preference from second to third for<br />

recycling. This is mainly due to emissions <strong>of</strong> NMVOC from the trucks, which is considered<br />

as benzene in the assessment <strong>of</strong> toxicological effects. However this change is not seen using<br />

the USES methods<br />

The same emission leads to changes in the rankings <strong>of</strong> treatment <strong>of</strong> the newspaper fraction<br />

also when considering human toxicological impacts. When using the USES-method for<br />

characterisation, both with maximum and minimum weight, recycling falls from first to<br />

second in ranking compared to the base and medium transport scenarios, leaving incineration<br />

as highest ranked.<br />

7.13 Comparison between a scenario with long transports and the base scenario. The table shows the weighted<br />

results for toxicological effects in SEK/year. The sub-categories have been weighted and added together into<br />

eco-toxicological effects (E-tox) and toxicological effects on human health (H-tox).<br />
