US-UK Collaboration on Exposure Science 
A joint meeting between the US Environmental Protection Agency, the Environment Agency and Defra on collaboration on exposure science was held on 7 October 2008. The presentations are available for download below. APRIL scientists played a significant role at this workshop which initiated collaboration between scientists in the UK and the USEPA.
The central purpose of this collaboration is to ensure that the most recent and scientifically credible knowledge, focusing on the formation, transformation, transport and dispersion of contaminants through the atmosphere and their removal from the atmosphere, is available for predicting future air quality, and for assessing, developing and implementing environmental regulations and decisions, both in the atmosphere and in the context of the aquatic and terrestrial biospheres. The benefit is that one organisation would be able to refer to a partner’s publications and on-going research, in support of its science-based decisions and to demonstrate the effectiveness of its regulation. The tripartite meetings will also promote useful dialogue between the organisations on topics of mutual interest.
