Abstract:		"Ships could emit an abundance intermediate volatility organic compounds (IVOCs). In recent years, many studies on the emission characteristics of IVOCs have focused on the burning of heavy fuel oil by ocean-going ships; however, few have focused on inland vessels which have a more significant impact on air quality and human health owing to their closer proximity to cities than ocean-going ships. In this study, the IVOC emission factors (EF(IVOCs)) of three inland vessels were determined using a dilution sampling system considering different influencing factors (ship age and operating conditions). The results showed that the EF(IVOCs) values ranged from 869.9 to 7607 mg/kg fuel, with an average of 4128 +/- 2703 mg/kg fuel. In addition, the age of the vessel was found to have a dramatic effect on emissions with the average EF(IVOCs) of inland vessels aged >10 years was 4300 +/- 4319, 5769, and 6484 +/- 1586 mg/kg fuel under cruising, idling, and maneuvering conditions, respectively, while that of vessels <10 years old was 1180 +/- 328.3 mg/kg fuel when maneuvering. The percentages of emission factors for unresolved complex mixture (UCM), normal alkanes (n-alkanes), branched alkanes (b-alkanes), and polycyclic aromatic hydrocarbons (PAHs) from inland vessels were 82.1 +/- 2.6 %, 5.2 +/- 0.9 %, 10.6 +/- 2.0 % and 2.0 +/- 0.6 % of the total IVOCs, respectively. The secondary organic aerosols (SOA) production of inland vessels was estimated to be 1212 +/- 801.7 mg/kg fuel, which was substantially higher than those of diesel vehicles, non-road construction machinery, and gasoline vehicles reported by other researches. Moreover, based on the ship movement and measured EF(IVOCs) data, the IVOCs emission inventory of inland vessels in Jiangsu Province and China in 2016 was 4.2 +/- 2.8 and 32.0 +/- 21.0 Gg respectively, which was comparable to those from diesel vehicle emissions"
