This picture is from a regular cyclist (who wishes to remain anonymous) who wears a pollution mask. It shows how blackened the mask becomes in less than three months – fumes which would otherwise be in his lungs.
The mask is a Respro Techno Gold. Used from 27/2/12 to 14/6/12. 3days per week. Middlewood to city centre and return then 3 miles up to S10.
The cyclist says “When a bus pulls away in front of me I cannot smell any fumes with the mask on.” Sheffield Greens want to encourage cycling as a fast, efficient and non polluting form of transport. However it is obviously a good idea to protect your lungs by wearing a mask when cycling in the city.
