摘要

The temperature distribution in Phnom Penh was measured using a car to evaluate the thermal characteristics and air pollution in the city. The measurements were made by using temp-hygro sensors with a data logger installed on the car roof and were conducted both during day and night to evaluate the influence of land use. The water temperature was also measured in the River Tonle Sap and the Mekong. By measuring the temperature as a function of distance from the banks of the Mekong and Tonle Sap, the cooling effect of the river was also investigated. Ambient particulates were simultaneously sampled at three different sites in the city along with NO2 and PAHs and heavy metal concentrations were analyzed. The temperature distribution was compared with the concentration of chemical compositions and NO2.
