英文摘要: We present determinations of fuel-based emission factors for formic acid (EFHCOOH) from light duty gasoline vehicles (LDGVs) and in-use ocean-going vessels. Emission ratios, from which the emission factors were derived, were determined from LDGVs through measurement of HCOOH and carbon dioxide (CO2) in the exhaust of a fleet of eight LDGVs driven under the California Unified Cycle at the California Air Resources Board's Haagen-Smit Laboratory. Emission ratios from in-use ocean-going vessels were determined through direct measurement of HCOOH and CO2 in ship plumes intercepted by the R/V Atlantis during the 2010 California Research at the Nexus of Air Quality and Climate Change (CalNex) campaign within 24 nautical miles of the California coast. The eight car fleet average EFHCOOH was 0.94 ± 0.32 (1σ) and 0.57 ± 0.18 mg (kg fuel)-1 for the cold start and hot running phases of the drive cycle, respectively. This difference suggests that catalytic converter performance and the air/fuel equivalence ratio are important metrics contributing to EFHCOOH. EFHCOOH was determined to be 1.94 ± 1.06 mg (kg fuel)-1 for a single diesel vehicle driven under highway driving conditions, higher on average than any individual LDGV tested. In comparison, HCOOH primary emissions from in-use ocean-going vessels were substantially larger, averaging 20.89 ± 8.50 mg (kg fuel)-1. On a global scale, HCOOH primary emissions from fossil fuel combustion are likely to be insignificant relative to secondary production mechanisms, however primary emissions may contribute more significantly on a finer, regional scale in urban locations. © 2014 Elsevier Ltd.
