The analysis of pollutants (NO2, NO, CO, PM10) emitted from the buses : a case study at Kuala Terengganu bus station

Abstract

Air pollution now is seems to be such major problems that people have to give more attention on it. So, the study that place at MPKT Bus Station are carried out in order to measure the amount of pollutants being emitted at the area. Study includes measurement of emission of N02, NO, CO and PM10 and also with its meteorological effect. N02, NO, CO gases were measured by using Draeger x-am Instrument. PM 10 was measured by using Casella Microdust Pro while windspeed was measured by using Casella Weather Station. The sampling activity done for 7 days which taken 8 hours in mid day. Highest percentage being emitted was CO which the amount is 70%. Concentration of N02 and NO is highest at SS which the value was 136.68ug/m 3 and 322.72ug/m3.CO and PM10 were highest at S3 and the value was 1255ug/m3 while PM10 value was 130.79ug/m3•It also indicated that most polluted area was S3 and S4 which nearest to the road. The trend of pollutants distribute at the area can be figure out. It is hope that, the government authorities will step up efforts to reduce the level of pollutants in the air especially at the area of MPKT Bus Station.
