The Institute of Air Quality Management (IAQM) has produced the above mentioned guide downloadable here.
The IAQM guidance document, the authors state, is not intended to be a primer on how to model air quality impacts but instead is intended to provide practical guidance for those air quality specialists who undertake air quality impact assessments and are already familiar with modelling techniques. It also aims to encourage greater communication and co-operation between air quality and ecological specialists.
The document can also be downloaded from the IAQM website here where other useful resources can be found.
The document has a Eurocentric base, using the UK and EU regulations as
a backdrop. However, with this in mind, professionals from other parts of the
world will benefit from the insights, guides, suggestions and bullet points
included in the text which can be extrapolated to local conditions and
circumstances.
