Etude de L’Influence D’Une Source Locale Naturelle Intense de Composes Organosoufres sur la Chimie de la Troposphere en Milieu non Pollue

摘要: In preparation to the study of mechanisms photooxidation biologically generated organosulfur Compounds in natural conditions, we have measured concentration different minor reactive atmosphere case a simple model, that an intense local source “unpolluted” environment. The site studied, Penmarc’h Britany, has large field algae which generates very quantity dimethyl sulfide. order path chemical transformation this Compound atmosphere, analyses for intermediate and related were carried out: Compounds, sulfur dioxide, ozone, nitrogen oxides carbonyl Compounds. Ozone monitered continuously by means commercial analyzers whereas dioxide out every 6 hours. It was necessary develop new sampling analysis techniques with high sensitivity
