C. Readings taken from the two monthly stations in Kensington have been taken for nine years and the following table com-pares the annual results:-
Year | No. of days exposed | Total weight of deposited matter in tons per square mile | Daily average of sulphur in milligrams of sulphur trioxide | ||
---|---|---|---|---|---|
North Kensington | South Kensington | North Kensington | South Kensington | ||
1954 | 364 | 205.1l | 181.47 | 2.15 | 2.57 |
1955 | 367 | 227.73 | 191.70 | 2.32 | 2.77 |

1962 | 365 | 119.68 | 93.64 | 2.78 | 2.43 |
* January 1961 readings not included in this figure as it was
found that the instrument had been disturbed.
General observations.
Whilst it is too early to assess whether the atmosphere in
Kensington is generally better as a result of the Council's
efforts in promoting smoke control areas, it is certainly gratifying
to see from the above figures that in the last eight years the
measurement of deposited matter in tons per square mile on a monthly
average basis has been reduced, in the case of North Kensington from
18.98 to 9.97, and in the case of South Kensington from 15.98 to
7.80. There are, of course, other factors to take into consideration
and it is unwise to express opinions on figures obtained locally
in comparatively small areas.
