EUROPEAN SAMPLING INTERCOMPARISONS FOR AROMATIC AND CHLORINATED HYDROCARBONS IN WORKPLACE AIR

摘要

Thirty-eight laboratories of the EU Member States, representing government, manufacturers of personal samplers, industrial and university laboratories have participated in a quality assurance scheme which allows to evaluate errors associated with both the sampling and analytical step of personal sampling methods. State-of-the-art bias, within and between laboratory coefficients of variation for pumped and diffusive methods currently applied are discussed. The data enable verification of compliance of the method-laboratory combinations with EN 482 and quantification of errors, in specific related to the sampling step. The merits of the project regarding improved procedures and results are discussed in detail.
