A study of the concentration and particle size distribution of dusts emitted in high-temperature processes

The aim of the project was to develop guidelines regarding occupational risk assessment for dusts emitted in high-temperature processes.A test method was developed as part of the project; the concentration and particle size distribution of dusts emitted in such high-temperature processes as combustion of Diesel fuel in Diesel engines and welding were tested. The results of those tests are discussed. Guidelines for occupational risk assessment for dusts emitted in high-temperature processes were developed on the basis of the test results. They list the principles of comprehensive assessment and optic methods of measuring the concentration and particle size distribution. Test methods are discussed in detail, they can be used for determining both the parameters of utrafine particles from high-temperature processes and nanoparticles emitted in nanotechnological processes.
