“…Our a priori hypothesis was that for children living adjacent to cultivated fields, passive exposure to drift of the pesticides used for the specific crop types was not negligible (Lu et al, 2000; Rubino et al, 2012). We selected a 100-meter buffer around homes since it represents the distance where substantial pesticide drift occurs according to some studies (Wittich and Siebers, 2002; Siebers et al, 2003; Martin, 2008; Wolters et al, 2008; Cornelis et al, 2009; Garron et al, 2009), taking into account that in Italy agricultural fields are sprayed only by ground-based devices and therefore larger drifts are difficult to assume (Tsakirakis et al, 2014). In particular, for arable crops, sprayers’ devices are kept in a horizontal position, very close to the plants, so the dispersion of pesticides is very limited.…”

Background Exposure to pesticides has been suggested as a risk factor for childhood leukemia, but definitive evidence on this relation and the specific pesticides involved is still not clear. Objective We carried out a population-based case-control study in a Northern Italy community to assess the possible relation between passive exposure to agricultural pesticides and risk of acute childhood leukemia. Methods We assessed passive pesticide exposure of 111 childhood leukemia cases and 444 matched controls by determining density and type of agricultural land use within a 100-m radius buffer around children’s homes. We focused on four common crop types, arable, orchard, vineyard and vegetable, characterized by the use of specific pesticides that are potentially involved in childhood induced leukemia. The use of these pesticides was validated within the present study. We computed the odds ratios (OR) of the disease and their 95% confidence intervals (CI) according to type and density of crops around the children’s homes, also taking into account traffic pollution and high-voltage power line magnetic field exposure. Results Childhood leukemia risk did not increase in relation with any of the crop types with the exception of arable crops, characterized by the use of 2.4-D, MCPA, glyphosate, dicamba, triazine and cypermethrin. The very few children (n=11) residing close to arable crops had an OR for childhood leukemia of 2.04 (95% CI 0.50–8.35), and such excess risk was further enhanced among children aged < 5 years. Conclusions Despite the null association with most crop types and the statistical imprecision of the estimates, the increased leukemia risk among children residing close to arable crops indicates the need to further investigate the involvement in disease etiology of passive exposure to herbicides and pyrethroids, though such exposure is unlikely to play a role in the vast majority of cases.

“…proximity and pesticide levels (Curwin et al, 2005;Ward et al, 2006). Evidence has also shown that pesticides sprayed on fields can drift from the spraying area by up to 400 m (Fenske et al, 2002;Koch et al, 2002;Siebers et al, 2003;Quandt et al, 2004;Carlsen et al, 2006;Wolters et al, 2008) and 750 m (Ward et al, 2006). Moreover, living with a farmworker has been associated with an increase in pesticide concentrations in the household (Gibbs et al, 2017;Bennett et al, 2019;López-Gálvez et al, 2019;Dereumeaux et al, 2020).…”

Agricultural production is a critical economic activity in many African countries, where pesticides are used extensively to improve crop yield and quality. Potential health effects resulting from indoor exposure to agricultural pesticides are very concerning and children are particularly vulnerable. This case study examined indoor exposure to and risks from agricultural pesticides. Indoor air samples were collected on spraying days from households of 15 pesticide applicators and 12 non-applicators in communities close to (~200 m) and surrounded by sugarcane fields in Eswatini (formerly Swaziland), Southern Africa. Liquid chromatography with tandem mass spectrometry (LC-MS/MS) analysis of samples revealed mean concentrations of 0.75, 0.32, 0.57 and 0.004 µg m -3 for ametryn, atrazine, pendimethalin and 2,4-dichlorophenoxyacetic acid (2,4-D), respectively, in the applicator households

“…Similar to Xue et al, Wang et al [17] measured that 90% of drift droplets of a fuel powered single-rotor UAV are within 9.3-14.5 m under the wind speed of 0.76-5.5 m/s. Compared with the conventional boom sprayer [20,21], the droplets drift distance of UAV sprayer would be further.…”

As a new low volume application technology, unmanned aerial vehicle (UAV) application is developing quickly in China. The aim of this study was to compare the droplet deposition, control efficacy and working efficiency of a six-rotor UAV with a self-propelled boom sprayer and two conventional knapsack sprayers on the wheat crop. The total deposition of UAV and other sprayers were not statistically significant, but significantly lower for run-off. The deposition uniformity and droplets penetrability of the UAV were poor. The deposition variation coefficient of the UAV was 87.2%, which was higher than the boom sprayer of 31.2%. The deposition on the third top leaf was only 50.0% compared to the boom sprayer. The area of coverage of the UAV was 2.2% under the spray volume of 10 L/ha. The control efficacy on wheat aphids of UAV was 70.9%, which was comparable to other sprayers. The working efficiency of UAV was 4.11 ha/h, which was roughly 1.7–20.0 times higher than the three other sprayers. Comparable control efficacy results suggest that UAV application could be a viable strategy to control pests with higher efficiency. Further improvement on deposition uniformity and penetrability are needed.
