ABSTRACT

From January 2005 to December 2009, a total of 457 and 444 samples were collected respectively rains in humid savannas of Djougou and Lamto. Using Henry's law, we determined the content in the air of the major organic monoacid (HCOOH and CH3COOH) from their concentration in rainwater. At Lamto, annual partial pressure of formic acid (FA) and acetic acid (AA) on the five year study is very little variable. It covers a range of 0.1 ppbv and 0.2 ppb to 0.4 to 0.7 ppbv respectively for formic acid (FA) and acetic acid (AA). While in Djougou, it is very variable. It varies from 0.01 to 0.19 ppbv to formic acid (FA) and 0.04 to 0.54 ppbv to acetic acid (FA). For both stations, it is a two times higher in the dry season than the wet season factor. This difference is related to the enrichment of a monoacid organic acid content in the air by supplying various sources of these acids. However, the correlation analysis that enables the production of formic acid (FA) and acetic acid (AA) Djougou like Lamto is not related to the marine source although the latter is close to the Gulf of Guinea.
