This article presents a new investigation by CONCAWE (the oil companies' European organisation for environment, health and safety), which gives detailed and comprehensive results on the concentrations of benzene in air around a service station over a period of one year. The study was conducted at a service station in the UK, where the average benzene content of the petrol sold was about 1%. Atmospheric benzene concentration data were collected at nine points, four around the service station, four on the road nearby, and one remote. This enabled the estimation of the following levels of benzene concentrations: (1) due to service station activities; (2) produced by passing traffic; and (3) background. Two sampling techniques were used, and then compared. They produced somewhat different results for mean benzene-in-air concentrations, and explanations of these differences are offered. Lower mean benzene concentrations were found than in CONCAWE's previous study, mainly because: (1) the sampling protocols were different, with the new results aiming to determine long-term averages which can be compared to air quality standards; and (2) the service stations were different. CONCAWE is now confident that it understands properly the methodology and resource requirements for making surveys of the annual average concentration of benzene in air.
