Emission of Aerosol Black Carbon in the Atmosphere of Chhattisgarh
Aerosol Black Carbon (ABC), is the major anthropogenic component of atmospheric aerosols. Being produced by all combustion processes, it is chemically inert and hence has a significantly long lifetime. Real time measurements of the mass concentration of ambient ABC have been made of exists over Chhattisgarh. Annual variations show highest concentration during dry winter months of December– February and lowest values during the monsoon months of June–September. Apportionment to total aerosol mass concentration shows that about 8–10% share for ABC. The fine particulate (PM2.5) and coarse particulate (PM10) samples were collected on preheated quartz fibre filters with Sequential Speciation Sampler (Model 2300 USA).ABC concentration is found to be in the range 5–81 gcm−3.The details and implications will be presented.
