Description: Das Projekt "Study on diesel engine particle emission and determining of parameters for estimating soot particle concentrations in air" wird vom Umweltbundesamt gefördert und von Bergbau-Berufsgenossenschaft, Institut für Gefahrstoff-Forschung durchgeführt. Objective: The aim of the research work is as follows: - to assess pollution by measuring particulate diesel engine emissions in underground non-coal mines in relation to the engine operation cycle and operating and ventilating conditions, - to obtain information on pollution at comparable workplaces in coal mining by building simple mathematical models and verifying them, without having to take measurements in coal mines, - to measure other diesel engine exhaust gas components and compare individual components or combination thereof to enable pollution to be assessed such that the method for determining soot emission is largely independent of primary incinerable substances, - to test filter retention capacity in relation to operating times, - to reduce soot emissions and personal pollution, - to simplify measurement and analysis methods, - to ensure that assessment methods are universally applicable, - to identify interference which can arise between individual assessment methods. General Information: The component of diesel engine exhaust gases with the highest carconogenic potential is soot and the organic compounds deposited thereon. It is above all these particulate emissions which are universally acknowledged to be responsible for the carcinogenic effects of diesel engine emissions demonstrated in tests on animals. This is why the Committee for Harmful Substances in the Federal Republic of Germany has based assessment of pollution from diesel engine emissions at the place of work. Thanks to the development of analysis methods based on separation of soot particles by filtration, where the difference in weight is determined after incinerating the soot or the soot concentration is calculated by coulometric measurement of the carbon dioxide, workplaces at which the airborne dust does not contain a substantial amount of organic carbon can now be monitored by measurement instruments. However, the sensitivity of this method and the verification limits have still to be determined. Any interference which might arise from other non-carbon bound substances will also be investigated. The researchers will also establish which sampling method is most suitable for various concentration ranges. The method cannot be used in coal mining as the airborne dust there mainly contains carbon. Tests are to be carried out in other mines to determine what links, if any, exist between soot emissions from various vehicles and pollution in the mine air. These tests must also take into account the extent to which soot from diesel exhausts is deposited on coarse dust and can no longer reach the alveolae. The aim of the research is to determine what factors might be sufficiently indicative of pollution in coal mines without carrying out measurements. Regulations on harmful substances and Council Directive No 1107 permit this type of assessment by analogy. The researchers will also examine whether there are any links between soot emission and other substances, or ...
