Content	MEGA evaluations for the preparation of REACH exposure scenarios for aniline 1 Introduction The measured data for workplace exposure evaluated in the following have been gathered and documented in accordance with the principles of the measurement system of the German social accident insurance institutions for exposure assessment (MGU1, formerly BGMG). The quality of the MGU is upheld by a quality management system that in essence satisfies the requirements of DIN EN ISO 9001. The test laboratories are operated in accordance with DIN EN ISO 17025 “General requirements for the competence of testing and calibration laboratories”. To measure aniline exposure at the workplace, a defined volume of air is sucked by a suitable pump through a silica gel tube. The hazardous substance contained in the air is adsorbed by the silica gel tube. Qualitative and quantitative analysis are performed by gas chromatography with a nitrogen phosphorus detector. The quantification limit is 0.05 mg/m³ for a test air volume of 40 L. Source: Amines, aliphatic II and aromatic II (ref. no. 6073). In: IFA-Arbeitsmappe Messung von Gefahrstoffen. 45. Lfg. X/2010. Ed.: Deutsche Gesetzliche Unfallversicherung (DGUV), Berlin. Erich Schmidt, Berlin 2011 – loose-leaf edition. All the surveyed data in the MGU are brought together in the MEGA exposure database (measured data on exposure to hazardous substances at the workplace). If individual values fall below the measurement method’s analytical quantification limit, half the value is adopted in the evaluation. The MEGAPro software developed by the IFA (formerly BGIA) makes it possible to statistically analyse the data of the MEGA exposure database on the basis of various selection criteria and evaluation strategies. 1 Gabriel, S.; Koppisch, D.; Range, D.: The MGU – a monitoring system for the collection and documentation of valid workplace exposure data.
