“…In a later study ( , ), size-segregated aerosol was simultaneously collected for 11 h in Camden, NJ, 5 km downwind of a municipal incinerator and at a background site in a suburb of Philadelphia, 12 km to the northwest (see Figure ). Two sets of samples were collected when the Camden site was downwind of the incinerator.…”

“…More recently, Dodd et al (10) showed that important information on the structure and dynamics of primary particulate emissions from generic sources could be inferred from the size distributions of intrinsic tracer species derived from ultratrace analysis of highly resolved submicrometer aerosol fractions. Later, Divita (12,18,19) developed size distributions for >20 elements (including V, As, Se, Sb, Zn, and S, i.e., elements strongly associated with oil combustion, coal combustion, municipal incineration, and intraregionally transported secondary aerosol) in >50 samples collected in nonindustrial and industrial urban environments in and around Washington, DC, and Philadelphia, PA. Herein, we review the pertinent findings of these and other studies and use the information to develop the extended paradigm shown in Figure 1. The intent is to extend the Whitby paradigm to encompass primary accumulation aerosol components, to better convey the rich complexity of the ambient urban aerosol, and thus to provide a more suitable framework for quantifying the dose of urban aerosol toxins.…”

Discussions of excess mortality and morbidity from exposure to urban aerosol particles typically invoke the now 20-year-old trimodal aerosol paradigm proposed by Whitby to explain the structure and behavior of ambient aerosol volume and its major constituent, sulfate. However, this paradigm largely ignores the primary high-temperature combustion (HTC) components of the urban aerosol, which contribute minor amounts of the aerosol mass, but carry the bulk of the particulate toxins and numbers of aerosol particles. Studies encompassing the analyses of >100 size distributions of important intrinsic tracers of primary particles from HTC sources collected over the past decade in various environments show that urban aerosol contains a complex mixture of physically-discrete fresh and aged, primary particle populations from a variety of sources. Furthermore, whereas the behavior of fineparticulate aerosol mass and sulfate was described in terms of coagulation and accumulation aerosol scavenging of new secondary sulfate nuclei, studies reviewed herein suggest that the behavior of primary aerosol is mediated more by hygroscopic growth and cloud processing, accompanied by oxidation of SO 2 on wet particles and droplets. We conclude that the distribution of airborne particulate toxins and their atmospheric behavior is far more complex than commonly conceptualized on the basis of the classical trimodal model, and we develop an extended paradigm in which the focus is on the primary accumulation aerosol.

The present work reports the results of a first study of elemental composition in airborne particulate matter (fine and coarse) collected at the Municipality of Centro Habana, Havana City, Cuba, using the PIXE technique. At present, there is not any information available about element contents in airborne particulate matter from this region. A five months sampling campaign was carried out, collecting the samples under an air flux of 20 l/min with a Gent SFU Sampler equipped with a system which allows the aerosol collection in both size fractions simultaneously. A total of 144 aerosol samples were collected. For the PIXE analysis, the samples were irradiated by 2.0 MeV energy protons from a 2MV Tandetron Accelerator. A total of 14 elements ( S , Cl , K , Ca , Ti , V , Cr , Mn , Fe , Ni , Cu , Zn , Br and Pb ) were consistently detected with minimum detection limits from 1 ng/m3 to 10 ng/m3 for most of the elements. Enrichment factors were also calculated for both fractions in order to identify the natural and anthropogenic group of elements. The quantitative results obtained have revealed important information that has been used in a first attempt to understand and to characterize the atmospheric pollution of this area.
