In this study, a mobile sampling equipment was developed in order to measure mercury (Hg) concentration and its species from mobile sources. First, three different fuel types were analyzed for their original Hg contents. Hg emissions from gasoline, diesel, and LPG (Liquefied Petroleum Gas) vehicles were also measured and speciated (particulate, oxidized, and elemental mercury). Fuel analysis showed that LPG had highest Hg content, followed by gasoline and diesel. For all three vehicles, Hg concentrations at driving modes were higher than at idling modes. Furthermore, Hg emissions from LPG vehicle was highest of all three vehicle types tested, both at idling and driving modes, as expected from the fact that it had the highest original fuel Hg content. |
