Metrological Department Peshawar. The climatic condition for each period (morning, noon and
after noon) of each sampling day is given in Tables 1.
The average concentration of CO measured along with climatic condition at seven sampling points
has been given in Tables 2.
• On Saturday (Table 2) at evening (2:00pm to 4:00pm) CO was below detection limit at
all the sampling point. The minimum average concentration was 0.28ppm in the morning
(8:00am to 10:00 am) and maximum was recorded 2.0ppm. The average concentration at
morning and noon has been recorded 0.35ppm and 1.5ppm respectively, which is very
low from the permissible limit of WHO as given in Tables 2.
• On Sunday the average CO level at measuring sampling points in Hayatabad is presented
in Table 2. The concentration was minimum in the morning and maximum at noon that
was 0.28ppm and 2.14ppm respectively. The average concentration in morning, noon and
after noon was found to be 0.28ppm, 2.57ppm and 1.9ppm respectively.
• At each of the sampling point the CO level on Monday; (Table 2) was below detection
limit (DBL) in the morning, 1ppm in noon and a maximum of 4.0ppm at afternoon. The
average concentration at noon and afternoon was 1.0ppm and 3.5ppm respectively, which
is below the permissible limit.
• On Tuesday, (Table 2) in all the three visits at each measuring point the CO level was
found below detection limit (DBL).
• The CO concentration measured on Wednesday is given in (Table 2). It is an average of
0.36ppm in morning and 2.0ppm in noon and afternoon. The average level for the day
was 1.45ppm.
• On Thursday, (Table 2) in the morning no CO has been detected at any of the sampling
point. The average level recorded at noon and afternoon is 0.21ppm and 0.49ppm
respectively.
• Table 2 also present the CO level measured at Friday. In morning and noon the average
concentration has founded 0.35ppm and 2.5ppm respectively and was below detection
limit at after noon.
• On all the sampling points in the Hayatabad the CO level was not found to be higher than
that of permissible limit of WHO standards, which is 9ppm for carbon monoxide. So
from CO point of view the air quality around the Hayatabad is suitable for breathing.
• The concentration of nitrous oxide NO recorded on the sampling points for one week has
been given in the same tables described earlier for CO.
• On Saturday, (Table 2) the minimum concentration in morning was 0.35ppm and
maximum was 1.0ppm at after noon. The average concentration of NO at morning, noon
and afternoon was recorded 0.71ppm, 0.85ppm and 1.0ppm respectively.
• Table 2 presented the Sunday data. It shows minimum concentration 0.57ppm, 1.0ppm,
