This is a pre-recorded webinar. It is available for 2 weeks from 16 May to 16 June 2022. Fee = £295.00 plus VAT or 2 credits
This webinar will address fundamental issues associated with the practicalities of assessing air quality via measurement. The trainer will facilitate a sharing of knowledge and experience of using passive diffusion tubes to monitor concentrations of ambient
nitrogen dioxide. The webinar will cover detailed siting requirements and data quality as well as providing an overview of the precision and accuracy of diffusion tubes. We will include a worked example of a bias adjustment calculation, which is necessary
for submitting data to Defra and the Devolved Administrations. This will be followed by drawing on experience of setting up and operating a diffusion tube network. The webinar will provide a review of laboratory inter-comparisons and how to find information
on your laboratory’s performance. The trainers will also cover other monitoring techniques, including advice on monitoring particulate matter, and give an overview of the correction model to use; the use of automatic gaseous analysers, how to calibrate
them and the data ratification process.
The webinar stands alone but can be also be undertaken as the second module of the EMAQ+ Essentials of LAQM course - a structured programme of training leading to the Certificate in Local Air Quality Management (LAQM) - which is accredited by the Institute
of Air Quality Management (IAQM).
