Air pollution from airborne particulates is a global issue that has received some attention due to potential health issues and environmental impacts. Construction activities, agricultural operations, combustion of fossil fuels, and industrial and mining processes are significant sources of particulate pollution. The potential to cause health problems has been linked to size, concentration and chemical composition of suspended particles. Duration of exposure and receptor’s susceptibility also determine potential to cause health effects. Particles that are 10 microns in diameter or smaller evade natural defence mechanisms and enter the lungs to cause serious health problems. Particulate matter is also found to reduce visibility, cause environmental and property damage and alter local weather. This paper reviews relevant literature on ambient air particles with specific focus on emission sources, potential threats and mitigation techniques. It is observed in the literature that particle pollution can lead to irritation of eyes, nose and throat; coughing, chest tightness and shortness of breath; reduced lung function; irregular heartbeat, asthma and heart attacks; and premature death in people with heart or lung disease.
