“…[20] The use of trifluralin in the EU was ,3200 t year À1 before its ban in the EU member states in 2009. [21] Concentrations .1000 pg m À3 of gaseous trifluralin were recently observed in the eastern and central regions of France, [3,22] but published data on trifluralin in the air of agricultural regions in other European countries are sparse. Pesticides in the air over the German Bight can be significantly influenced by the agricultural activities in the adjacent continent.…”

Environmental context. The occurrence of pesticides in remote areas such as high mountains and the Arctic demands an understanding of their regional environmental fate. We investigate the levels and sources of currently used pesticides and legacy pesticides in the air and seawater of the German Bight. Volatilisation from local surfaces and long-range transport were the major sources of these chemicals to the air, whereas riverine input and atmospheric deposition by air-seawater exchange were the main sources of these chemicals to the seawater.Abstract. Surface seawater and air samples collected from the German Bight (North Sea) in March, May and July 2010 were analysed for hexachlorobenzene (HCB) and hexachlorocyclohexanes (HCHs), five currently used pesticides (CUPs) (trifluralin, endosulfan, chlorpyrifos, dacthal and quintozene) and pentachloroanisole (metabolite). Volatilisation from local surfaces was considered to be the main source of these chemicals to the air (excluding trifluralin). Long-range transport from Western Europe partly contributed to the higher air concentrations observed in July whereas riverine input was the main source for HCHs and pentachloroanisole in seawater in March. Air-sea gas exchange of HCB and a-HCH in the German Bight was found to be near equilibrium, probably reflecting the past use of these chemicals, their wide dispersal in the environment and lack of contemporary use. Deposition of target compounds from the air to seawater was observed to be much higher in July compared with depositional fluxes for March and May, except for chlorpyrifos (with volatilisation fluxes in all sampling periods: ,25 ng m À2 day À1 ). Concentrations of trifluralin in seawater appear to have decreased since its restriction of use in European Union member states, with net volatilisation from seawater observed in March (flux: 6.3 AE 7.2 ng m À2 day À1 ). With the exception of chlorpyrifos, our results indicate that volatilisation from local sources combined with long-range transport from Western Europe and subsequent deposition are important pathways for these compounds to German Bight seawater during summer periods.

“…Seasonal trifluralin releases into the atmosphere can be as high as 25% of that applied and the maximum residues of trifluralin in the air above treated fields are in the range of 2-3 g m −3 following application [10]. Trifluralin, a persistent compound in the atmosphere [11], was found in air, rainwater and microlayer [12,13]. The particle phase of trifluralin accounted for ∼3% of total trifluralin in the atmosphere [14].…”

“…Therefore, the first run involved only the contribution of the A Total Suspended Particulate (TSP) high volume air sampler (Tisch Environmental Inc., Cleves, OH, USA) with a flow rate between 40 and 60 ft 3 /min (1.1-1.7 m 3 /min) equipped with rectangular QM-A quartz fibre filters for aerosols with a thickness of 450 µm (Whatman plc, Maidstone, Kent, UK) was used for the experiment. This instrumentation has been widely described in literature to assess the presence of pesticides residues and other compounds in atmosphere [68][69][70][71][72][73][74][75]. The on-site measurement campaign was carried out in three days, the 30 June, 1 July and 14 July 2014.…”

This work originates from an epidemiological study aimed to assess the correlation between population exposure to pesticides used in agriculture and adverse health effects. In support of the population exposure evaluation two models implemented by the authors were applied: a GIS-based proximity model and the CAREA atmospheric dispersion model. In this work, the results of the two models are presented and compared. Despite the proximity analysis is widely used for these kinds of studies, it was investigated how meteorology could affect the exposure assessment. Both models were applied to pesticides emitted by 1519 agricultural fields and considering 2584 receptors distributed over an area of 8430 km 2 . CAREA output shows a considerable enhancement in the percentage of exposed receptors, from the 4% of the proximity model to the 54% of the CAREA model. Moreover, the spatial analysis of the results on a specific test site showed that the effects of meteorology considered by CAREA led to an anisotropic exposure distribution that differs considerably from the symmetric distribution resulting by the proximity model. In addition, the results of a field campaign for the definition and planning of ground measurement of concentration for the validation of CAREA are presented. The preliminary results showed how, during treatments, pesticide concentrations distant from the fields are significantly higher than background values.
