Recording of Atmospheric Pollution
The recording of atmospheric pollution is carried out at two stations within the
Borough viz. at the Town Hall and at the Treatment Centre, Seven Sisters Road. The
concentrations of sulphur dioxide and smoke in the atmosphere are recorded daily and
the findings are sent to the Warren Springs Laboratory for collation and comparison
with other Metropolitan areas in order that an overall picture may be obtained for the
whole of London.
A summary of the recordings from the Borough Council sites is set out in the
following tables:-
