Background: There is a strong need for laboratory in vitro test systems for the toxicity of airborne particulate matter and nanoparticles. The measurement of oxidative stress potential offers a promising way forward. Objectives: a workshop was convened involving leading workers from the field in order to review the available test methods and to generate a Consensus Statement. Discussions: workshop participants summarised their own research activities as well as discussion of the relative merits of different test methods. Conclusions: in vitro test methods have an important role to play in the screening of toxicity in airborne particulate matter and nanoparti- cles. In vitro cell challenges were preferable to in vitro acellular systems but both have a potential major role to play and offer large cost advantages relative to human or animal inhalation studies and animal in vivo installation experiments. There remains a need to compare tests one with another on standardised samples and also to establish a correlation with the results of population-based epidemiology.
