This book was released on 2012 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diesel exhaust emissions include levels of volatile organic compounds and particulates that can be harmful to the health of both humans and the environment. Polycyclic aromatic hydrocarbons (PAH) are often associated with particulates and can be absorbed through dermal contact, inhalation or ingestion. Exposures to excess occupational amounts of diesel exhaust have been linked to an increased risk of lung cancer; however, research supporting a possible connection between diesel exhaust and bladder cancer has yet to be agreed upon. The current study measured diesel exhaust exposure of construction workers in the Elbe Tunnel in Hamburg, Germany. The study examined the validity of using urinary 1-hydroxypyrene (1-HP) as a biomarker of exposure to diesel exhaust by determining a statistical association between levels of 1-HP and the presence of DNA adducts which may contribute to tumor induction. Thirty-five urine samples from construction workers were measured by analyzing the levels of 1-HP in worker's pre- and post-shift urine samples collected over a six week period. Urinary 1-HP was detected using HPLC fluorescence techniques. DNA adduct levels were measured in exfoliated urothelial cells using a 32P-postlabelling assay. Each sample was double-blinded and the identifiers were not released until the results were completed. All thirty-five samples analyzed for urinary 1-HP contained levels below both the ACGIH recommendation of 1 [micro]g/L and the population background level of 0.2 [micro]g/L. The pre- and post-shift data for urinary 1-HP levels showed no statistical significance. There was no observed statistical significant association between urinary 1-HP and DNA adducts. A weak negative association between 1-HP and DNA adducts was observed (Pearson r=-0.313). Due to the variation of the results in this study combined with the lack of additional information concerning confounding data, no conclusions can be made that support the relationship between urinary 1-HP and DNA adduct levels. This study was a precursor to a larger study that will evaluate PAH breathing zone exposure, hand wipes from exposed construction workers, DNA adduct levels and 1-HP levels to find a correlation between cumulative external dose and internal effect. These baseline data will be a precursor to further epidemiological studies that attempt to determine the potential connection between diesel exhaust exposure and risk of bladder cancer.

This book was released on 2011 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diesel particulate matter is widely considered as a possible human carcinogen. Several classes of organic components such as polycyclic aromatic hydrocarbons (PAHs), nitrated PAHs (NPAHs) and aliphatic hydrocarbons can adsorb on the soot surface. Although diesel particulate filters (DPFs) have been designed and implemented to reduce these and other harmful diesel emissions, the particle loaded filters may act as a rection chamber for side reactions whose products could possibly offset the positive effects of the DPF itself. Scope of the present dissertation was to explain to which extent modern DPFs could support the formation of highly toxic and mutagenic NPAHs by nitration of pre-existing PAHs. In addition, the use of biofuels and biofuel blends in different vehicles was investigated with respect to the effects on NPAHs emission.

Available in PDF, EPUB and Kindle. Book excerpt: This project investigated the exhaust emissions produced at various operating conditions by the 6.5L diesel engine that is used to power the Army's GMMWV. Compared to reference diesel fuel, the use of JP-8 fuel resulted in lower levels of NOx and particulate matter. Polycyclic aromatic hydrocarbons (PAH's) were also determined. The JP-8 produced lower levels of exhaust PAH's than the low sulfur certification diesel fuel (LSCD) for most but not all PAH type.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The present dissertation investigated the interaction of soot-adsorbed PAH with NO2 both in laboratory model systems and in real diesel engines exhaust. Scope of the experiments was to explain to which extent modern diesel particulate filters (DPFs) could support the formation of highly toxic and mutagenic nitro-polycyclic aromatic hydrocarbons (NPAH) by nitration of pre-existing PAH. Results demonstrated that NPAH formation is possible and actually occurs depending on the operating conditions. In addition, the use of biofuels in different vehicles was investigated with respect to the effects on NPAH emission. In an EURO V truck and in an EURO V diesel car, NPAH concentrations in the exhaust were not significantly different from those of fossil fuel. In an EURO V otto-cycle car and an the EU III A tractor, emissions from biofuels were sensibly lower.
