Abstract
Indoor air pollution in a closed room is one of the air pollutions that gives serious threats to human health . O ne of them comes from vehicle gas emissions in the closed parking area. This research identifies and analyses CO concentration measured in Mall X parking man’s breathing zone with closed parking area and in Mall Y semi-opened parking area . CO measurement carried out by passive sampling method using Personal Dosimeter Tubes . The m easurement result of CO gas concentration to parking man’s breathing zone in Mall X was 25 – 81,25 ppm with the average value in 50 ± 26,15 ppm. Meanwhile, CO gas concentration in Mall Y g a ve result 3,13 – 12,5 ppm with the average value in 7,88 ± 4,36 ppm. Correlation value between CO concentration and its intake in Mall X area was 0,9983, meanwhile correlation value between CO concentration and its intake in Mall Y area was 0,9903. I t was concluded that CO gas concentration measured in parking man’s breathing zone influence d the differences in CO intake value in significance value . Keywords: carbon monoxide, indoor air pollution, passive sampling, vehicle emission
