Chemical characterization of particulate emissions from diesel engines: A review
TL;DR: In this paper, the chemical properties of particulate matter (PM) in diesel vehicle exhaust at a time when emission regulations, diesel technology development, and particle characterization techniques are all undergoing rapid change are examined.

Microwave-assisted extraction and ultrasonic extraction to determine polycyclic aromatic hydrocarbons in needles and bark of Pinus pinaster Ait. and Pinus pinea L. by GC–MS
TL;DR: A field study with naturally contaminated samples from eight sites showed that needles are more suitable biomonitors for PAHs, yielding concentrations from 2 to 17 times higher than those found in bark.

Determination of dibenzopyrenes in standard reference materials (SRM) 1649a, 1650, and 2975 using ultrasonically assisted extraction and LC–GC–MS
TL;DR: The method’s limit of quantification (LOQ), based on analyses of SRM 1649a, is in the range 10–77 pg, and by use of this method more than 25 potential PAH isomers with a molecular weight of 302 could be separated.

Determination of 252-302 Da and tentative identification of 316-376 Da polycyclic aromatic hydrocarbons in Standard Reference Materials 1649a Urban Dust and 1650b and 2975 Diesel Particulate Matter by accelerated solvent extraction-HPLC-GC-MS.
TL;DR: The results show that accelerated solvent extraction can extract PAHs more efficiently from diesel PM than ultrasonically assisted extraction, and they show thatPAHs are more difficult to extract from dieselPM than from urban air particles.

Levels and Sources of PAHs in Selected Sites from Portugal: Biomonitoring with Pinus pinea and Pinus pinaster Needles
TL;DR: Despite the apparent matrix similarities between both pine species, P. pinaster needles revealed higher mean entrapment levels than P. pinea, and PAH molecular ratios revealed the influence of both petrogenic and pyrogenic sources.

Characterization of Polycyclic Aromatic Hydrocarbons in Motor Vehicle Fuels and Exhaust Emissions
Linsey C. Marr,and Thomas W. Kirchstetter,Robert A. Harley,Antonio H. Miguel,Susanne V. Hering,S. Katharine Hammond +5 more
TL;DR: In this article, the authors quantified polycyclic aromatic hydrocarbon (PAH) emissions in gasoline and diesel fuel samples collected in summer 1997 in northern California and found that Naphthalene was the predominant PAH in both fuels.

Microwave extraction. A novel sample preparation method for chromatography
TL;DR: The microwave extraction method was more effective than the traditional Soxhlet or shake-flask extraction methods and suitable for fast extractions of large sample series.

Microwave-assisted solvent extraction of environmental samples
TL;DR: In recent years, microwave assisted extraction has attracted growing interest as it allows rapid extractions of solutes from solid matrices, with extraction efficiency comparable to that of the classical techniques as mentioned in this paper.
