Identification of sources of aerosol in Chicago by chemical element mass balance

A chemical element mass balance (CEB) receptor model was used to determine the contributions from coal combustion, cement and limestone, mobile sources, refuse incineration, soil and steel industries to the ambient particulate matter in Chicago. Twenty four hout average measurements were made of in...
