Over eighty delegates attended the January 2007 London Air Quality Network seminar, making it the largest to date.

The seminar focused on two themes:

1. New Issues in NO2 and PM10 - including updates to the WHO guidelines, the challenges of meeting EU Limit Values in Austria and incorporating primary NO2 emissions in the London inventory.

Two speakers from King’s focused on PM10; the evidence for increasing concentrations of primary PM10 from London and the results of a pilot project to use FDMS measurements to make TEOM PM10 measurements gravimetrically equivalent.

2. Congestion Charging and the Low Emission Zone - speakers from GLA, TfL, London School of Hygiene and Tropical Medicine, St George’s Medical School, and King’s presented the research programmes to assess the air pollution changes arising from Congestion Charging and the Low Emission Zone.

Sessions were chaired by Martin Williams from Defra and Bob Maynard from the Health Protection Agency.

Several speakers have given permission for their presentations to be published on the LondonAir web site. These may be found by following the link below:
