Abstract Rapid developments of ports, international trade, and the shipbuilding industry in China have negatively affected the ambient air quality of the coastal zone due to shipping emissions. However, there is still lack of on-board measurement data about the emission factors for gaseous species and particulate matters.
In this study, three diesel engine-power vessels (including one engineering vessel and two scientific research vessels) and two fishing vessels in offshore China were tested to investigate the emission factors (EFs) of various gaseous and particulate pollutants and to estimate their total emissions in China. Gaseous species were measured online and included CO2, CO, NOx, HC and SO2, and particulate matter samples were collected onboard and analyzed for OC, EC, water-soluble ions, as well as various metal elements.
For the engine power vessels, the measured EFs of CO, NOx, HC, PM, and SO2 were 30.2, 115, 23.7, 9.40 and 1.60 g per kg fuel for the engineering vessel, and 6.93-9.20, 31.6-35.7, 1.24-4.18, 0.16-0.72 and 0.92-2.62 g kg-1for the two research vessels, respectively. While for the fishing vessels, the EFs were 27.0-43.9, 48.9-63.6, 0.33-0.61, 4.79-9.74, and 1.32 g kg-1, respectively. Operating modes also significantly affected the emissions factors for all vessels. OC and EC were the main constituents of the PM emitted from the fishing vessels, while water-soluble ions and metal elements accounted for only a small part. Based on these data, a total of 231, 368, 3.10, and 47.6 thousand tons of CO, NOx, HC, and PM, respectively, as well as 2,016 million tons of CO2 were estimated to emit from marine fishing vessels in China in 2010.
