Air Quality Monitoring in Industrial Area of Orchard Street, Batam City, based on PM2.5 and Carbon Monoxide (CO)

Orchard street is one of the main streets in Batam City that is often passed by the driver. Pollution in this street not only comes from transport emissions but also from the industrial area. One of the impacts of industrial activity is an increase in air pollution levels in the form of both gas and particulates that have the potential to decrease the ambient air quality. This study was conducted by direct measurement in the field consist of PM2.5 and Carbon Monoxide (CO) gas in every 6 hours with 7 sampling points. Furthermore, the calculated green space was conducted by Google Earth to know about the absorption level of green space. The result showed that the PM2.5 level was less than 45 ug/m³, CO level was about 7.67 – 35.83 ppm. For the absorption level of green space in the near study area was 15.6 kg CO/day.
