The recently published paper by Rühl et al. (2006) describes the results of measurements of exposure to bitumen fumes and vapours in a variety of industries where hot bitumen is handled in Germany. Overall, it is to be applauded that results of studies assessing exposure in a variety of industries and workplaces are being published in peer-reviewed literature and do not stay hidden in large inaccessible databases or grey literature. We consider the Annals of Occupational Hygiene to be the world-class forum for publishing such studies and it has done so increasingly over the last two decades. Given that quantitative exposure data are becoming more and more essential to modern epidemiology for establishing exposure–response relations and risk assessment (Stewart et al., 1996; Loomis and Kromhout, 2004
