For several days now there have been moderate pollution warnings but
today, Friday, this has turned to 'High' and people are advised to
stay indoors. So cyclists beware and we can thank the many motorists
on our roads for contributing to that harmful pollution.

ITYF it's not "motorists", but London buses, taxis and goods vehicles
and European power stations and agriculture that are the main problems.

No, road traffic is the main problem in London and cars are 80% of all
road traffic. Also petrol vehicles are mainly responsible for benzene
which is carcinogenic.

At what concentration **** for brains?

Oh dear, oh dear : Simples thinks that the concentration of benzene in the air from traffic just
happens to be the same as the H&S limit for industry.
