SECTION H
DISEASES OF ANIMALS
Throughout the year, the Borough remained free from any
outbreak of notifiable disease, although there were numerous outbreaks
throughout the country which necessitated exercising the
utmost vigilance to see that no animals were moved into the
Borough from infected areas.
SECTION J
ATMOSPHERIC POLLUTION
There has been no major change in the siting or recording of
the three deposit gauge and seven lead peroxide stations and analyses
have been maintained throughout the year.
ESTIMATION OF ATMOSPHERIC SULPHUR BY THE
LEAD PEROXIDE METHOD
The monthly figures for each station for the years 1957 and
1958 are shown on page 42 and the 1958 figures are illustrated
graphically on page 43.
The station with the highest monthly figure—4.6 and with
the highest average figure—2.7 was Bashley Road. The station
with the lowest monthly figure—0.4—and with the lowest average
figure—1.7—was Acacia Road.
The average of all stations for the year was 2.0 which is
slightly above that of the previous year.
DEPOSIT GAUGES
The monthly figures for each station are shown statistically on
page 44 and graphically on page 43.
The yearly average figure—15.60 tons/sq. mile—has risen
very slightly above that of the previous year although the amount
of combustible material in the deposit has again increased by a
small amount.
Once again the station with the greatest monthly deposit—
24.6 tons/sq. mile — and the greatest average deposit — 18.44
tons/sq. mile — was Bashley Road. The Kendal Avenue gauge
showed the lowest monthly deposit of 8.01 tons/sq. mile and the
lowest average deposit of 13.26 tons/sq. mile.
