TLDR
In this paper, the Langmuir adsorption concept was introduced for three-to-five-ring polycyclic aromatic hydrocarbons in the vapor phase and in the particulate phase (PAHs/sub pat) and total suspended particulate (TSP) in ambient air.Abstract:
Three- to six-ring polycyclic aromatic hydrocarbons in the vapor phase (PAHs/sub vap/) and in the particulate phase (PAHs/sub pat) and total suspended particulate (TSP) in ambient air were sampled and determined year-round. At ambient temperature levels, substantial amounts of three-to five-ring PAHs were found in the vapor phase depending upon temperature (T, K) and the six-ring PAHs were all found in the particulate phase. For three- to five-ring PAHs, the Langmuir adsorption concept was introduced for PAHs/sub vap/ and PAHs/sub pat/ on the particulates. log ((PAHs/sub vap/) /)(PAHs/sub pat/) / (TSP))) was related to 1/T, and a high correlation (r = 0.834 to -0.942) was obtained between the two quantities. Thus, aspects of the three- to five-ring PAHs in ambient air were considered to be explained by using the Langmuir adsorption concept.read more

TL;DR: In this paper, the authors assess current data in this area, develop global scale estimates of the atmospheric fluxes of trace elements, mineral aerosol, nitrogen species, and synthetic organic compounds to the ocean; and compare the atmospheric input rates of these substances to their input via rivers.

An absorption model of GAS/Particle partitioning of organic compounds in the atmosphere
TL;DR: In this article, the governing equations were developed for absorptive partitioning into an organic material (om) phase making up part of the TSP, and the equations indicate that absorption could well be an important sorption mechanism in the urban environment.

PAH source fingerprints for coke ovens, diesel and, gasoline engines, highway tunnels, and wood combustion emissions
TL;DR: In this article, a modified high-volume sampling method (PS-1 sampler) was employed to collect airborne polyaromatic hydrocarbons (PAHs) in both the particulate and gas phases.

Measuring and simulating particulate organics in the atmosphere: problems and prospects
TL;DR: A review of the current state of organic aerosol sampling, analysis, and simulation, examines the limitations of current technology, and presents prospects for the future is provided in this article, where the emphasis is on distilling findings from recent atmospheric, smog chamber, and theoretical studies to provide a coherent picture of what has been accomplished, especially during the last five years.

An absorption model of the gas/aerosol partitioning involved in the formation of secondary organic aerosol
TL;DR: In this article, a partitioning model is developed to allow the modeling of the dynamics of secondary organic aerosol (SOA) formation, where gas/aerosol partitioning is assumed to be governed by equilibrium partitioning into an absorptive, well-mixed liquid (or at least amorphous) organic matter (om) phase.
