4. What are the advantages and disadvantages of the presented effect analysis
approaches?
5. Describe the procedure on how to apply site-dependent impact assessment
in the framework of the overall methodology introduced in Chapter 6.
6. Discuss whether there are limits for the usefulness of end-of-pipe tech-
nologies in light of the results in the case study on the installation of
different levels of advanced gas treatment systems.
7. What are considered to be the main uncertainties in environmental damage
estimations for industrial process chains? What are the next steps ahead
to reduce them?
8. Calculate the incremental damage caused in air by the emissions to air of
200 kg of a pollutant with a fate and exposure factor F p air,air = 2.5 ¥ 10 –5
–6
and an effect factor E p air = 1.2 ¥ 10 .
9. Calculate the DALY for the egalitarian case and external cost of discount
3
3
rate = 3% per person for a PM emission increment of 2 ¥ 10 mg/m .

urban area of Massachusetts with a population density r = 550 per-
2

sons/km , is I Massachusetts = 0.18. Calculate the incremental receptor exposure
per mass of pollutant in a farming area of New Hampshire with a popu-

lation density r = 90 persons/km .
