Development of Air Quality Profile in Enclosed Car Park with Emphasis on Particulate Matter 10 μmand Carbon Dioxide

Air pollution has increased tremendously and gives the most dangerous threat
compare to other pollutions because it cause the greatest adverse effects to health and
loss of welfare. Statistics has shown that the increasing of pollutants available in the
atmosphere is parallel to increment number of vehicles. There are few research
conducted to investigate air quality inside enclosed car park. Hence, study of air
pollution is significant as the first action towards improving the air quality. The aim
of this study to monitor emission of particulate matter 10 μm and carbon dioxide and
evaluate state of air quality inside this enclosed car park. These pollutants are
analysed to determine the effect of them to human health. Enclosed car park in Kuala
Lumpur has been chosen as study area. The sampling is conducted from 6th
November 2014 until 17th November 2014 and data (concentration) are collected
every 2 minute interval for 24 hours. The following pollutants; particulate matter 10
μm and carbon dioxide are measured by using AQM 60. This equipment is placed
beside an office at this car park area. The obtained data are analysed by using time
series analysis. The concentration of particulate matter 10 μm and carbon dioxide are
compare with their standard guidelines which is the permissible limit to be exposed.
Concentration that exceed the limit will cause health implication to visitors and
employees of the car park due to long term exposure. Permissible limit for particulate
matter 10 μm is 50 μg/m3 as recommended by MAAQS for 12 month exposure and
carbon dioxide is 1000 ppm recommended by U.S. EPA for continuous exposure.
From the result obtained, concentration of particulate matter 10 μm exceed the
allowable limit at certain hour especially at noon. It might affect the human health,
especially to employees at this car park. Concentration of carbon dioxide below the
limit at all time. Good maintenance is needed to maintain the concentration carbon
dioxide below the limit.
