Daily Measurement of Suspended Matter
The Council has apparatus for making daily estimations of smoke installed at the
London School of Hygiene and Tropical Medicine, Keppel Street, and at the Royal
Institute of Public Health and Hygiene, Queen Square. The apparatus consists mainly
of an air pump which draws a known volume of air from outside and passes it through
a white filter paper. The amount of smoke collected is estimated by comparing the stain
on the paper with a calibrated scale of shades. The following recordings were obtained
during 1962:—
