Report no. 96/59: In 1995 the World Health Organization/European region (WHO/EU) proposed a 1-hour exposure guideline of 0.11 ppm for NO2. This guideline is based on a 50%uncertainty factor applied to a LOAEL of 0.20 to 0.30 ppm for 1 to 2-hour experimental exposures...
Report no. 96/58: The World Health Organization (WHO) regional office for Europe recommends an SO2 guideline of 500 μg/m3 (0.175 ppm) for a 10-minute sampling time, an uncertainty factor of 2, and a threshold of about 1000 μg/m3 (0.35 ppm). Based on SO2 chamber...
Report no. 95/63: This report describes the results obtained from measurements of ambient benzene levels around a single service station in the UK over a one year period. Continuous sampling was achieved using diffusion tubes and results compared with those from...
Report no. 7/94: This report summarizes over 2,000 occupational exposure data on benzene,measured in the period 1986-1992. Exposures for the various types of jobs are reviewed against a number of timeweightedaverage (TWA) criteria, including 1 ppm and 0.5 ppm. Most of...
Report no. 94/53: CONCAWE initiated a programme to measure the ambient air concentrations of benzene in the vicinity of a number of gasoline stations and distribution terminals in Europe. The steps in the programme were: review previous studies measurement...
