Abstract
Particulate matter (PM) is the main determinant of air pollution caused by a variety of natural and human-caused sources. Because it can be suspended in the atmosphere for long periods of time and travel long distances, it can cause a major health crisis for humans and damage the environment as well. Studies are still required to understand how the PM moves around obstacles, especially in urban areas. In this study, small scale experiments were carried out to look into the effects of simple obstacles, heights and distance from the source on the PM10 concentration. Results show that when obstacle heights and distance from the source increase, the PM10 average concentration decrease. Also, turbulence created by the obstacles affects the PM10 concentration in both sensors before and after the obstacle, mainly in cases of high wind speed. In addition, the use of incense sticks as a source of PM pollution illustrated that moderate burning of incense sticks in indoor places could skyrocket the PM10 concentration to an unhealthy level.
