DIESEL-ENGINED VEHICLES SUCH AS TAXIS, PUBLIC LIGHT BUSES, PASSENGER COACHES, FRANCHISED BUSES AND LIGHT AND HEAVY GOODS VEHICLES ARE THE GREATEST CONTRIBUTOR OF PARTICULATE MATTER. OTHER SOURCES INCLUDE INDUSTRY, FURNACES AND BOILERS, CONSTRUCTION ACTIVITIES, THE SEA AND THE SOIL.

NOTE TO EDITORS:
