“…Some previous studies also found that the hazard potential of a 2-stroke engine was higher than that of a 4-stroke engine for the comparison of air pollutants (e.g., hydrocarbons and volatile organic compounds) emission from different engine type motorcycles (Tsai et al, 2003a-b). The PCDD/F I-TEQ emission concentrations in this study are also higher than those (0.93-45 pg I-TEQ/Nm 3 ) for unleaded gasoline vehicles in literature (Marklund et al, 1987;Bingham et al, 1989;Hagenmaier et al, 1990;Marklund et al, 1990;Oehme et al, 1991).

“…Intensive studies have focused on the PCDD/F emissions from various sources, such as municipal waste, metallurgical activities and temples, due to their vast majority of the total PCDD/F contribution Wang and Chang-Chien, 2007;Hu et al, 2009a-c;Wang et al, 2010a-b). Only limited studies paid attention to traffic PCDD/F emissions (Marklund et al, 1987;Bingham et al, 1989;Hagenmaier et al, 1990;Marklund et al, 1990;Oehme et al, 1991;Geueke et al, 1999;U.S. EPA, 2001;Kim et al, 2003), and no information on PCDD/F emission from motorcycles is available in literature.…”

This study presents the first investigation of polychlorinated dibenzo-p-dioxin and polychlorinated dibenzofuran (PCDD/F) emission from (six 2-stroke and six 4-stroke engine) motorcycles using chassis dynamometer tests. Effects of engine type and lubricant renewal on PCDD/F emission were also evaluated. The mean total PCDD/F emission concentration of tested motorcycles was 1.06 ng/Nm 3 , with a corresponding mean total PCDD/F I-TEQ of 0.0671 ng I-TEQ/Nm 3 . The mean PCDD/F emission concentration of 2-stroke engine motorcycles (1.17 ng/Nm 3 , 0.0727 ng I-TEQ/Nm 3 ) was more than that (0.912 ng/Nm 3 , 0.0534 ng I-TEQ/Nm 3 ) of 4-stroke engine motorcycles. The PCDD/F emission factors of motorcycles were comparable to those of some types of vehicles, although the tested motorcycles equipped with cylinders much smaller than those of vehicles. The dominant PCDD/F congeners of 2-stroke and 4-stroke motorcycles in emission priority were OCDD, OCDF, 1,2,3,4,6,7, and 1,2,3,4,6,7, accounting for 37%, 15%, 10% and 9% of the total PCDD/F emission, respectively. The reductions of PCDD/F and I-TEQ emissions after lubricant renewal of the 4-stroke motorcycles were 26%-45% and 41%-63%, respectively.

“…Releases from the combustion of diesel and leaded fuels are significant sources in urban environments, where automobile and shipping traffic increased with post-World War II economic expansion (Buchert and Ballschmiter, 1986;Marklund et al, 1990). Several point and nonpoint sources of these compounds are present in Newark Bay (USEPA, 1987;NJDEP, 1989).…”

“…Estudo desenvolvido na Suécia, por Marklund et al 7 (1990) mostrou que os veículos a gasolina com adição de chumbo tetraetila apresentavam emissão de dioxinas, enquanto os veículos a gasolina sem chumbo emitiam furanos. Os veículos diesel testados não apresentaram emissão nem de dioxinas nem de furanos acima do limite de detecção do método empregado, ressalvando-se que o óleo diesel utilizado não continha cloro.…”
