Particulates and policy — the role of models
In the companion article in this Review (pp. 6–9) we examine the current state of understanding on the sources of particulate matter (emission inventories) and their contribution to ambient levels in the air we breathe (source apportionment). This serves to highlight...![Ambient particulate matter: sources and apportioning](https://www.concawe.eu/wp-content/uploads/rehj-671x675.jpg)
Ambient particulate matter: sources and apportioning
The quality of the air we breathe has become an increasingly important and emotive issue over the past few years. To date, the regulation of air quality has focused mainly on outdoor air (even though for particular pollutants, indoor concentrations may be greater and...![Environmental levels of benzene at the boundaries of three European refineries](https://www.concawe.eu/wp-content/uploads/9957-625x675.jpg)
Environmental levels of benzene at the boundaries of three European refineries
Report no. 99/57: A year-long study of benzene-in-air concentrations at the boundaries of three refineries has been carried out.The sampling technique employed was passive diffusion tubes. Sampling locations were fixed at 12 or 16 points around the...![Best available techniques to reduce emissions from refineries](https://www.concawe.eu/wp-content/uploads/9901-1-554x675.jpg)
