ATMOSPHERIC POLLUTION RECORDING (Continued)
The following table shows the results obtained from this station
during the year:-
VOLUMETRIC ANALYSIS - SMOKE AND SO2
| Month | Average daily total | |
|---|---|---|
| Microgrammes per cubic metre | ||
| Smoke | SO2 | |
| January | 193 | 430 |
| February | 138 | 323 |
| March | 172 | 469 |
| April | 58 | 266 |
| May | 53 | 212 |
| June | 45 | 180 |
| July | 43 | 171 |
| August | 25 | 139 |
| September | 74 | 132 |
| October | 195 | 334 |
| November | 211 | 405 |
| December | 473 | * 1057 |
* The large increase in this figure was due to the dense and
persistent fog which settled over London in December from the third
to the seventh. Concentrations of sulphur dioxide reached a level
similar to or slightly higher than in 1952, but pollution by smoke was
distinctly lower. The emission of smoke has been reduced over the
last few years by the creation of smoke control areas and an increasing
trend by the public in the use of smokeless forms of heating.
