Measurement

Personal exposure

Advances in sensor technology means that individuals can now monitor air pollution levels themselves using relatively cheap, accurate and straightforward portable equipment. 

Exposure

Consequently, the exposure misclassification inherent in the fixed site measurement stations and questionnaires model of exposure assessment can now be addressed using a combination of personal exposure assessment and modelling.

MeasurementA number of different systems have been deployed to assess a combination of gaseous and particle metrics across a wide range of the population, from nursery toddlers to cycle couriers. 

This has demonstrated both the short term variations in exposure; typically from the journey to and from work.
