Air pollution
There were no particular foggy incidents in 1960. Comparisons are now available for
the past seven winters of the average levels of pollution based on the seven recording
stations described in appendix B to my report for 1956.

It will be seen that whereas there has been a downward trend in ' smoke ' since 1955.56
there has been less change in ' sulphur dioxide In a paper† read to the Clean Air Conference
(1960) the reduction in smoke in London is reported as due mainly to a big drop
in domestic coal consumption: the decrease in smoke emission in London has been much
greater than elsewhere in the country. This has not been matched by a corresponding
reduction in sulphur dioxide because ' the fall in the emission of sulphur dioxide from the
domestic burning of coal is more than offset by the low.level emissions from the sharply
increasing use of fuel oil in industry '.
