Farmer populations living in houses inside vegetable gardens are exposed to indoor pesticide pollution. The pulverization drift and volatile pesticides transported by wind are important sources of indoor pollution, which can be mitigated by hedgerows. This study was the first attempt in Brazil to investigate the efficiency of six different hedgerow species in reducing pesticide residues in air. A fluorescent compound (p-aminobenzoic acid or PABA) was introduced in the sprayed pesticide fluid that traced the pesticide in the water. Samples were collected in Petri dishes positioned on stakes at different heights in front of and behind the hedgerows. Data indicated barrier efficiency of up to 99%. Simulation of nontarget drift contamination with herbicide concentrations exhibited reduced senescence effects on leaves and posed no threat to survival. Hedgerows are feasible, simple, and inexpensive techniques, which may be used easily by farmers, independent of external support and efficiently mitigating indoor pesticide pollution, thus protecting human health.

使用树篱来减轻农村地区人口的农药暴露

居住在菜园内房屋中的农民人口暴露于室内农药污染。风带来的粉化漂移和挥发性农药是室内污染的重要来源，可以通过绿篱来缓解。这项研究是巴西首次尝试调查六种不同树篱物种在减少空气中农药残留方面的效率。一种荧光化合物（p-氨基苯甲酸或 PABA) 被引入喷洒的农药液体中，以追踪水中的农药。样品收集在培养皿中，培养皿放置在树篱前后不同高度的木桩上。数据表明阻隔效率高达 99%。除草剂浓度对非目标漂移污染的模拟显示出对叶片的衰老影响降低，并且对生存没有威胁。树篱是可行、简单、廉价的技术，农民可以轻松使用，无需外部支持，有效减轻室内农药污染，从而保护人类健康。2022 年整合环境评估管理；18：19–24。© 2021 SETAC
