So what does this mean? 

The European Union have set a legal mean annual limit for nitrogen dioxide (NO2) at 40g/m3.

 Our results are a mixture of under and over the level at which the mean annual limit is set.

 

They show a snapshot of the air pollution for the place and time we were monitoring

and are not directly comparable to annual data.

However, they could be a really powerful way to raise the issue of air pollution in our area. 

It is clear, for instance, that levels of pollution in Southall are far too high.
