ATMOSPHERIC POLLUTION
The routine measurement of atmospheric pollution at the four stations in the City of London
continued during the year. The results are set out in the Tables which follow.
TABLE 1 — Deposit Gauge.
The rainfall collected was the highest for many years, e.g. approximately five inches fell in
each of the months of September and October.
During a year of heavy rainfall it is expected that the amount of soluble and insoluble matter
deposited in the collecting bowl would be very much greater than normal. In fact the yearly
average for 1960 was considerably below the average for the two previous years and lower for the
average of the five years 1955-1959. Attention was drawn in the last annual report to the connection
between the deposits of a tarry nature and the smoke emitted from chimneys. The downward
trend in this deposit continued in 1960.
