This project seeks to evaluate the relative importance of the               various sources of atmospheric formaldehyde, formic acid and acetic             acid at remote continental locations within the US from the isotopic            composition of collected samples.                                                   At chosen locations:                                                            (a) The carbon isotopic composition of atmospheric formaldehyde             will be determined and compared to the compositions of the principal            sources at those sites - methane and natural non-methane                        hydrocarbons.  The relative contributions of these sources to the               carbon flux through formaldehyde to carbon monoxide should thus be              evaluated.                                                                          (b) The carbon isotopic compositions of formic acid and                     non-formic light mono-carboxylic acids will be determined and                   compared to each other, to formaldehyde and to other major organic              emissions, both anthropogenic and natural, to deduce likely source              contributions.                                                                      Specifically the project will refine existing collection and                work-up techniques, determine the 13C and 14C content of the three              atmospheric species, estimate the 13C content of local plant                    emissions, and determine the relative anthropogenic influence.
