“…As can be seen, seven pesticides could be quantified in most samples. Metsulfuron methyl ( in air were also found in previous studies performed in various countries including France, Germany, Canada, and Japan [7,8,9]. Atmospheric contamination by pesticides in rural and urban areas are also apparent from these data, as shown by recent work carried out in the east of France [9].…”

“…Indeed, it is well documented that the atmosphere and rainfall constitute an efficient vector for the dispersion of semi-volatile or volatile organic substances such as pesticides [2,3,4,5]. Moreover, several recent studies in Europe, North America, and Japan have revealed that the use of pesticides in the field can result in the transfer of these compounds into the atmosphere or rainfall, and their diffusion in urban areas not involved in agricultural activity [5,6,7,8,9,10,11]. Also, a number of toxicological investigations have shown the harmful effects of pesticides on human health [12].…”

The extensive use of pesticides to protect agricultural crops can result in the transfer of these compounds into the atmosphere and their diffusion towards urban areas. Precise evaluation of the geographic impact of this type of pollution is important environmentally. In this paper, analytical methods for the sampling, characterization, and determination of agricultural pesticides in air were developed; the methods were then applied in the Paris and Champagne regions. Sixteen pesticides belonging to nine chemical families were monitored. Sampling was carried out in urban (Paris) and rural (Aube district) sites, utilizing either a high-volume pump (12.5 m3 h(-1)) (urban site) or a low-volume pump (2.3 m3 h(-1)) for the rural site. Quartz filters and polyurethane foams (PUF) were used for sampling in all cases. After extracting the samples and concentrating the recovered solutions, high-performance liquid chromatography (HPLC) analysis with UV detection was performed. Identification of the pesticides was confirmed by applying to the HPLC measurements a novel UV-detection procedure based on the normalized absorbance variation with wavelength (Noravawa procedure). The presence of metsulfuron methyl, isoproturon, linuron, deltamethrin (and/or malathion), and chlorophenoxy acids (2,4-D and MCPP) was found at the urban sampling site at levels ranging from about 1 to 1130 ng m(-3) of air, depending on the compound and sampling period. On the rural sampling site residues of isoproturon, deltamethrin (and/or malathion), MCPP, and 2,4-D were generally detected at higher levels (19-5130 ng m(-3)) than on the urban site, as expected. The effects of the weather conditions and agricultural activity on the atmospheric concentrations of pesticides are discussed, as are long-range atmospheric transfer processes for these pesticides.

“…Halobenzonitrile pesticides were found in rain samples (Haraguchi et al, 1995) and in the gas phase (Pendleton and Jenks, 1984;Fujimori et al, 1991;Haraguchi et al, 1994;Hu¨skes and Palm, 1992), which are pathways for their deposition and accumulation in the aquatic environment (Waite et al, 1995). However, only a few data exist on their abiotic degradation reactions with the exception of bromoxynil.…”

“…The intensive use of pesticides all over the world led to ubiquitous contamination of exposed and remote areas, not only in water [1,2,3,4,5,6] and soil [7,8] but also in the atmosphere [9,10,11,12,13,14,15,16,17,18,19,20,21,22], as a result of drift during spraying [22,23], volatilisation and wind erosion [24,25,26,27,28,29]. It is known that air is a good pathway for transportation and re-deposition leading to the contamination of non-target areas [30] and may induce some risks for human health [31,32], wildlife and forest ecosystems [9,20,33].…”

An air sampling and analytical method based on adsorption on porous polymer (Tenax TA) followed by automatic thermal desorption (ATD) and GC/MS analysis was developed for ten pesticides commonly used on major crops in Britanny and some of their metabolites in air (from spray drift and volatilisation transfer processes): alachlor, atrazine (and two major degradation products: deethylatrazine and deisopropylatrazine), carbofuran, cyprodinil, epoxyconazole, iprodione (and 3,5-dichloroaniline), lindane (and -HCH, its isomer), metolachlor, terbuconazole and trifluralin. This method was established with special consideration for optimal thermal desorption conditions, linear ranges, limits of detection and quantification. Moreover, collection efficiencies of Tenax TA at room temperature were examined. This method was then applied to the determination of ambient pesticide levels during the spraying season at a rural area. The method was also applied to determine the vertical gradient of alachlor concentrations on a treated maize parcel to evaluate volatilisation fluxes.
