Abstract [en]

Air pollution from coal combustion is of great concern in China because coal is the country's principal source of energy and it has been estimated that coal combustion is one of the main sources of polycyclic aromatic hydrocarbon (PAH) emissions in the nation. This study reports the concentrations of 15 PAHs including benzo[a]pyrene, dibenzo[a,l]pyrene, dibenzo[a,e]pyrene, dibenzo[a,i]pyrene and dibenzo[a,h]pyrene in a coal fly ash certified reference material (CRM) from China. To the best of our knowledge, dibenzo[a,l]pyrene, dibenzo[a,i]pyrene and dibenzo[a,h]pyrene concentrations in coal fly ash particles have not previously been reported. Benzo[a]pyrene is the only one of the studied hydrocarbons whose concentration in the coal fly ash CRM had previously been certified. The concentration of this species measured in this present work was twice the certified value. This is probably because of the exhaustive accelerated solvent extraction method employed. Consecutive extractions indicated an extraction recovery in excess of 95% for benzo[a]pyrene. For the other determined PAHs, repeat extractions indicated recoveries above 90%.

Abstract [en]

Very recently, air pollution was declared the world’s single largest environmental health risk by the World Health Organization. The goal of this thesis is to contribute to a better assessment of air pollution through the development of novel and exhaustive extraction methods for the analysis of polycyclic aromatic hydrocarbons (PAHs), which are mutagenic and carcinogenic air pollutants.

The methods were developed and validated for the extraction of PAHs in both the semi-volatile fraction and particulate matter with application to samples derived from major sources of PAHs (diesel exhaust, coal fly ash and wood smoke samples). Pressurized liquid extraction was used because it allows a high sample throughput with reduced solvent requirements and analysis time compared to other traditionally used techniques, such as Soxhlet extraction.

The results presented herein show that the extraction conditions used when analyzing PAHs need to be evaluated to avoid underestimating their concentrations. This is especially true for the human carcinogen benzo[a]pyrene, which is often used as an indicator in the cancer risk assessments of PAHs, and the dibenzopyrene isomers due to their potentially high carcinogenicities.
