Quality control of sampling and analysis for the personal monitoring of exposure to harmful vapoursFunded under: FP2-BCR 4
Personal monitoring of exposure to potentially harmful vapours is legally required. It is meaningful only if the results are accurate. It is often taken for granted that less than 20 % error upon sampling and less than 10 % error upon analysis are easily achieved. Intercomparisons with leading laboratories from government and from the chemical industry, however, have shown much larger errors on several occasions. Therefore, a project providing the means to measure quality control in this area was started in the framework of the BCR-programme. For sampling, a series of intercomparisons was started in which participants sample the same air, of known composition, using their own sampling system. For analysis, a certified reference material was developed with 1 microgram of benzene, toluene and m-xylene in stainless steel tubes containing tenax. Other CRMs are in preparation for thermal as well as solvent desorption.
