Main Emission Sources

Estimated total TPM, PM₁₀ and PM_2.5emissions in year 2005 were:

CAC	With Open Sources	Without Open Sources
TPM	17,573,269 tonnes	768,717 tonnes
PM10	5,829,674 tonnes	424,519 tonnes
PM2.5	1,259,826 tonnes	310,879 tonnes

Open sources (paved and unpaved roads, construction, agriculture, forest fires, etc) make up 94% of total particulate matter, 90% of total PM₁₀ emissions and 64% of total PM_2.5 emissions

The distribution of emissions among contributing source categories for the two PM size fractions is illustrated in the pie charts below.
