For four years (2012-2015), pesticides were analyzed in atmospheric samples in the Centre of Reims (France). Among the analyzed substances, 28 have been quantified at least one time during the 4 sampling years. The annual cumulated pesticide concentrations were respectively 158.8, 38.5, 84.5 and 86.6 ng m(-3) from 2012 to 2015, showing a great variability in the presence of pesticides in the atmosphere of the Centre of Reims. The top nine pesticides quantified in the atmosphere were cymoxanil, chlorothalonil and prosulfocarb reaching concentrations up to 13-14 ng m(-3) and folpel, cyazofamid, fluazinam, pendimethalin, fenpropidin and spiroxamine reaching concentrations between 1 and 5 ng m(-3). Among the nine predominant pesticides, seven of them were fungicides especially used against septoriose, mildew and oidium occurring as well in vineyard and arable crops. Herbicides quantified were those which are used in arable crops. Insecticides especially carbaryl, chlorpyrifos ethyl and lindane were negligible in the atmosphere. The role of meteorological conditions in the development of diseases and the application rates of pesticide was related to the presence of pesticide in the atmosphere.
