Mercury emission and speciation of coal-fired power plants in China
Mercury emission coal-fired power plants China
2010/2/21
Comprehensive field measurements are needed to understand the mercury emissions from Chinese power plants and to improve the accuracy of emission inventories. Characterization of mercury emissions and...
Influence of trans-Pacific pollution transport on acyl peroxy nitrate abundances and speciation at Mount Bachelor Observatory during INTEX-B
trans-Pacific pollution transport acyl peroxy nitrate abundances Mount Bachelor Observatory INTEX-B
2008/12/23
We present month-long observations of speciated acyl peroxy nitrates (APNs), including PAN, PPN, MPAN, APAN, and the sum of PiBN and PnBN, measured at the Mount Bachelor Observatory (MBO) as part of t...
Iodine and bromine speciation in snow and the effect of orographically induced precipitation
Iodine bromine speciation induced precipitation
2008/12/10
Iodine is an essential trace element for all mammals and may also influence climate through new aerosol formation. Atmospheric bromine cycling is also important due to its well-known ozone depletion c...

Application of synchrotron radiation for measurement of iron red-ox speciation in atmospherically processed aerosols
synchrotron radiation iron red-ox speciation atmospherically processed aerosols
2008/12/10
In this study, ambient atmospheric particulate matter samples were collected using a size-resolved impactor sampler from three urban sites. The purpose of this study is to gain a better understanding ...
Modelling iodide – iodate speciation in atmospheric aerosol: Contributions of inorganic and organic iodine chemistry
iodate speciation atmospheric aerosol inorganic organic
2008/12/3
The speciation of iodine in atmospheric aerosol is currently poorly understood. Models predict negligible iodide concentrations but accumulation of iodate in aerosol, both of which is not confirmed by...
Redox activity and chemical speciation of size fractioned PM in the communities of the Los Angeles-Long Beach harbor
Redox PM Los Angeles-Long Beach harbor
2008/11/25
In this study, two different types of assays were used to quantitatively measure the redox activity of PM and to examine its intrinsic toxicity: 1) in vitro exposure to rat alveolar macrophage (AM) ce...
PM speciation and sources in Mexico during the MILAGRO-2006 Campaign
PM speciation sources Mexico MILAGRO-2006 Campaign
2008/10/24
Levels of PM10, PM2.5 and PM1 and chemical speciation of PM10 and PM2.5 were measured during the MILAGRO campaign (1st to 31st March 2006, but extended in some cases until 6th April) at four urban, on...
