16. A Procedure for Ecological Tiered Assessment of Risks (PETAR)
Sammanfattning : Institutions in developed countries have proposed several Ecological Risk Assessment (ERA) procedures, and the majority of study cases have been carried out there. The use of (often expensive) existing ERA procedures in developing countries is questionable given their limited resources and scarce background information of relevance for risk assessments. LÄS MER
17. Characterization of soot in air and rain over southern Asia
Sammanfattning : Filter-based optical measurements of light absorbing particulate matter at awavelength of about 550 nm, here referred to as soot, in air and rainwaterhave been performed during the period from 1st June 2005 to 31th May 2009at Godavari in Nepal, Sinhagad in India and Hanimaadhoo in The Maldives.A method for determination of water-insoluble light absorbing matter inrainwater has been developed.

19. Bioaccessibility of Stainless Steels : Importance of Bulk and Surface Features
Sammanfattning : With increasing environmental awareness, the desire to protect human beings and the environment from adverse effects induced by dispersed metals has become an issue of great concern and interest. New policies, such as REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) within the European Community, have been implemented to reduce hazards posed by the use of chemicals on producers and downstream users.

20. Numerical approaches to droplet growth in atmospheric turbulence
Sammanfattning : The bottleneck problem of cloud droplet growth is one of the most challenging problems in cloud physics. Cloud droplet growth is neither dominated by con-densation nor gravitational collision in the size range of 15–40 μm in radius. Turbulence-generated collision has been thought to be the mechanism to bridge the size gap, i.e. LÄS MER
