Source apportionment using reconstructed mass calculations

Journal of Environmental Science and Health, Part A, 2013
A long-term study was undertaken to investigate the air quality of the Islamabad/Rawalpindi area. In this regard fine and coarse particulate matter were collected from 4 sites in the Islamabad/Rawalpindi region from 1998 to 2010 using Gent samplers and polycarbonate filters and analyzed for their elemental composition using the techniques of Neutron ...

Source apportionment in oil spill remediation

Journal of Environmental Monitoring, 2012
A pipe rupture during unloading led to a spillage of 350-700 tonnes of Caño Limon, a light sweet crude oil, into San Vicente Bay in 2007. Initial clean-up methods removed the majority of the oil from the sandy beaches although some oil remained on the rocky shores.

CMB Source Apportionment during REVEAL

Journal of Environmental Engineering, 1997
Source contributions to PM2.5 aerosol measured at Chilliwack and Pitt Meadows in the Lower Fraser Valley, B.C., Canada, during the REVEAL study, were estimated using chemical mass balance (CMB) receptor modeling. On average, motor vehicles accounted for 34 and 43% of PM2.5 at Chilliwack and Pitt Meadows, respectively.

Mesothelioma: Risk Apportionment Among Asbestos Exposure Sources

Risk Analysis, 2005
The mesothelioma epidemic in the United States, which peaked during the 2000–2004 period, can be traced to high‐level asbestos exposures experienced by males in occupational settings prior to the full recognition of the disease‐causing potential of asbestos and the establishment of enforceable asbestos exposure limits by the Occupational Safety and ...

PM2.5 Source Apportionment in China

2016
China has been facing a severe air pollution challenge in recent years. It is known that fine particulate matter is closely linked to haze. It is very important to have a good understanding of the formation mechanisms and sources of haze in China.

Optimized variable source-profile approach for source apportionment

Atmospheric Environment, 2007
Abstract An expanded chemical mass balance (CMB) approach for PM2.5 source apportionment is presented in which both the local source compositions and corresponding contributions are determined from ambient measurements and initial estimates of source compositions using a global-optimization mechanism.
