Seven ships were tested using portable emission measurement system. Particles from three ships were sampled using quartz-filters and analyzed using Thermal/Optical Carbon Analyzer and GC–MS. The emission factors of CO, HC, NOx and PM are 11.00–84.60g/kg, 22.75–98.88g/kg, 0.72–5.83g/kg and 0.15–9.53g/kg, respectively. In most cases, the ships emit larger quantity of pollutants during cruising. For...
Nitrogen oxides (NO x ) and black carbon (BC) emission factors (EF) of 440 on-road diesel trucks were determined by conducting on-road chasing studies in Beijing and Chongqing, China, in the winter 2010. NO x and BC EF distributions are reported. The median NO x EFs for trucks sampled on level roads in Chongqing and Beijing are 40.0 and 47.4g kg-fuel −1 , respectively...
