Similar tests carried out by County Investigation Committee
during 1949 in the cement producing area of Kent revealed
calcium content to be 23.7 per cent, of the total solids (or 34}
tons of calcium per square mile per month)., whilst the highest
individual reading for total deposits in the whole series of
tests was recorded at 146 tons per square mile per month. In
comparison, the highest reading for total deposits during the
local survey in Erith showed 57 tons per square mile per month,
the lowest reading being 16 tons per square mile per month.
Industrial dust is visibly evident in the Borough when east
and north-east winds are prevalent, and widespread deposits
have been observed on foliage and roofs at times coinciding
with and after fog dispersal.
