The recording is done in collaboration with the Fuel Research Station of the
Department of Scientific and Industrial Research, where results from local authorities
and other co-operating bodies throughout the country are received, collated and
analysed. Scientists at the Fuel Research Station suggest that a long period of
observation, preferably 5 years, is needed before reliable conclusions can be drawn
about the average level of pollution or about the rate at which it is produced.
The records now being collected can not only be compared with those of other
places, but they will serve for comparison in other periods of time and as more and
more smokeless fuel is used there should be a progressive improvement, so that in
time posterity may look back with interest on the records of Hendon' s murky past.
