渔船排放的污染物在世界范围内普遍被忽视，测量的排放数据严重短缺，特别是在中国。为此，本研究对中国12艘不同类型的渔船（包括刺网渔船、钓鱼渔船和拖网渔船）的污染物排放进行了船上测量，以研究其排放因子、特征和排放总量。CO2、CO、NOx、PM和SO2的平均EF分别为3074 ± 55.9、50.6 ± 31.7、54.2 ± 30.7、9.54 ± 2.24和5.94 ± 6.38 g（kg燃料）-1，高于之前对渔船的研究。与中速和低速发动机船舶相比，渔船上的高速发动机具有较高的CO EFs，但较低的NOxEFs。值得注意的是，当渔船在低负荷条件下，他们总是有较高的EF的CO，PM和NO2相比，其他操作模式。结果表明，2012年中国机动渔船排放的CO、NOx和PM分别为232、379和61.8 kt，分别占非道路移动的污染源排放总量的10.7%、10.9%和19.3%，渔船对大气污染贡献显著，尤其是南方地区。
Pollutants from fishing boats have generally been neglected worldwide, and there is an acute shortage of measured emission data, especially in China. Therefore, on-board measurements of pollutants emitted from 12 different fishing boats in China (including gill net, angling, and trawler boats) were carried out in this study to investigate emission factors (EFs), characteristics and total emissions. The average EFs for CO2, CO, NOx, PM, and SO2were 3074 ± 55.9, 50.6 ± 31.7, 54.2 ± 30.7, 9.54 ± 2.24, and 5.94 ± 6.38 g (kg fuel)−1, respectively, which were higher than those from previous studies of fishing boats. When compared to medium-speed and slow-speed engine vessels, high-speed engines on fishing boats had higher CO EFs but lower NOxEFs. Notably, when fishing boats were in low-load conditions, they always had higher EFs of CO, PM, and NO2compared to other operating modes. The estimated results showed that emissions from motor-powered fishing boats in China in 2012 (232, 379, and 61.8 kt CO, NOxand PM) accounted for 10.7%, 10.9%, and 19.3% of the total CO, NOxand PM emitted from nonroad mobile sources, which means significant contribution of fishing boats to air pollution, especially in southern China areas.
