Impact of using fishing boat fuel with high poly aromatic content on the emission of polycyclic aromatic hydrocarbons from the diesel engine

In order to clamp down on the illegal use of fishing boat fuel A (FBFA) and to reduce exhaust emissions in Taiwan, the residue from a desulfurization unit (RDS) and pyrolysis fuel oil (PFO) were added into FBFA with the ratio of 0.5% to form two new blended fuels (RDS0.5 and PFO0.5). The appearances of fuels from dark to light are RDS0.5, PFO0.5, and FBFA. The two new fuels have higher viscosity than FBFA, which may damage engines and reduce the misuse. The exhaust emissions of CO, HC, NO x , polycyclic aromatic hydrocarbons (PAHs), and carcinogenic potencies (BaPeq) were analyzed by the heavy duty diesel engine (HDDE) transient cycle test. The results show that RDS0.5 has significantly lower particulate matter (PM) emissions, while the PM emissions of PFO0.5 are higher than those of FBFA. In addition, the total PAHs emissions concentration of all three of fishing boat fuels increase from premium (regular) diesel fuel. However, RDS0.5 has relatively lower BaPeq emissions, which are usually considered as carcinogens, than the other fishing boat fuel.

Emissions from Using Viscous Agent-Treated Fishing Boat Fuel Oil: Tests with a Heavy-Duty Diesel Engine (HDDE) Dynamometer

et al. 2010

“…Because PAHs were mainly from the fuel combustion, especially from vehicle exhaust in urban area in subtropical zone without heating season (Bi et al, 2003;, PAHs emissions from local vehicle and industrial activities would not vary greatly depending on the relative stable traffic volume and industrial activities during the sampling period in Xiamen. Although the PAH content of a fuel (Lin et al, 2006a), biodiesel blends (Lin et al, 2006b;Yuan et al, 2007) and the Mn-based additive (Yang et al, 1998) had a strong influence on PAH and particulate matter emission from vehicles, there is at present no data for fuel quality assumed in Xiamen. However, the input of PAHs from upwind (north and northeast) sources might change due to the coal combustion in heating season although the wind direction did not change much (Table 1) (Guo et al, 2003).…”

Diurnal Variations of Particle-bound PAHs at a Traffic Site in Xiamen, China

Wang

Yan

et al. 2010

To improve our current understanding of the fate of particle-bound PAHs, which include potent mutagens and carcinogens, diurnal measurements of these compounds were carried out from 23 Oct to 31 Dec 2008 at a busy traffic site in Xiamen, China. The sum of 19 PAH concentrations showed a just noticeable day-night difference in the warmer period (from 23 Oct to 25 Nov) to a remarkable day-night difference in the colder period (from 26 Nov to 31 Dec). However, the average profiles of the 19 PAHs in the warmer and colder periods were very similar for both day and night samples. Atmospheric mixing seemed to have more influence on the diurnal variations in PAHs than photodecomposition resulting from solar radiation, because PAH concentrations showed negative correlation with air temperature but significantly positive correlation with the ratios of reactive to stable PAHs, such as benz [a] [g,h,i]perylene and fluoranthene to fluoranthene plus pyrene, the results showed that no significant differences were observed in PAHs sources between the warm and cold periods and a combination of grass, wood or coal combustion and petroleum sources in airborne particles might be the most significant contributors of PAHs. Gas-phase PAHs were calculated based on the theoretical gas/particle partitioning coefficients for 19 PAHs and a high fraction of daily exposure was attributed to particle-phase PAHs in most cases. The excess lifetime cancer risk in colder period was generally higher than in the warmer period. The total uncertainties were computed based on the simpler average error transfer formula.

“…(1) The fishing boat factor was indicated by the high loading of Flu, Pyr, BaP, and IcdP (Lin et al, 2006) and the low loading of metallic elements. The emission of metallic elements from fishing boats is less than that from vehicles because fishing boats do not employ tires or brake pads.…”

Measurement of Ambient PAHs in Kumamoto: Differentiating Local and Transboundary Air Pollution

We developed an index to investigate the effect of transboundary air pollution (TAP) on the air quality of Kumamoto City, Japan. We estimated the effect of TAP by using the index and positive matrix factorization (PMF). Polycyclic aromatic hydrocarbons (PAHs) and trace metals were analyzed from the daily samples of the Total Suspended Particles (TSPs) collected seasonally from Oct. 2014 to Aug. 2015. These chemical components exhibited high concentrations in spring and winter, which is consistent with the data in the literature. Pb was identified as the TAP tracer owing to its high concentrations in winter and spring. Indeno(1, 2, 3-cd)pyrene (IcdP) was used as the local emission tracer in Kumamoto on the basis of previous studies. We applied the IcdP/Pb ratio as the index. The index enables the detection of TAP in daily data sets. PMF identified six factors: soil and road dust, biomass and waste burning, heavy oil combustion, fishing boats, vehicle emission, and coal combustion. The average contribution of TAP on the days when transboundary pollution was high was evaluated as being 46%.
