Investigation of variations and trends in TSP concentrations in the Klang Valley region, Malaysia

Air pollution in the atmosphere by TSP is a problem that has been growing for the last few years due to rapid industrialization, population growth and urbanization in the Klang Valley Region. Suspended particle levels are monitored in ambient air quality network of their potential impact on human he...

The causes of highest TSP concentrations during southwest monsoon season due to lack of rainfall and the stable atmospheric conditions, which reduce the ability of atmosphere to disperse the pollutants.
