Nachweis und Bewertung von Gefahrstoffbelastungen auf Oberflächen im Rahmen der betrieblichen Gefährdungsbeurteilung -eine Bestandsaufnahme

摘要

In contrast to already well established methods for the determination of hazardous substances in workplace air, the measurement of surface contaminations still lacks standardization of the analytical procedures and assessment of results.The determination of surface contamination is influenced by various factors such as physical and chemical surface characteristics, specific properties of the analytes, as well as the technique used for sample collection. A quantitative assessment of the transfer of settled substances from a surface to human skin and the transport through the skin into the body is hardly possible. In general, the measurement of surface contamination in order to track contamination routes or validate cleaning processes can be a valuable addition to existing air measurements for workplace assessment.
