摘要

本研究旨在评估本格特农民经常面临的与农药有关的安全风险。评估了农药在土壤和作物中的残留,以及农民对农药的知识和做法。方法采用问卷调查法对38名农户进行调查,并用气相色谱法对土壤和作物样品进行分析。所有农户均使用1种以上农药,其中大部分农户使用3种农药(73.7%)。最常见的是有机磷(45.2%)。鉴定的农药品牌中有12种是杀虫剂,其余2种是杀菌剂。23家(60.5%)采用混合杀虫剂,主要是为了节省时间。喷洒农药时最常用的个人防护装备是防毒面具、手套和靴子。在土壤和作物样品中,毒死蜱阳性3份,其中2份超过最大残留限量(MRL)。氯氰菊酯阳性3例,均超过最大残留限量。在处理这些可能有害的农药时必须谨慎。必须遵守适当的设备维护、清洁和储存,以防止不必要的农药接触。农药公司和政府的农业部门必须努力对用户进行充分的教育,重点是安全处理农药。

Pesticide-related safety risks among vegetable farmers : a cross sectional study
This study was conducted to assess the pesticide-related safety risks that Benguet farmers face on a regular basis. Pesticide residue in soil and crops, as well as farmers' knowledge and practices on pesticide were assessed. Methods consisted of survey questionnaire among 38 farmers, and the use of gas chromatography for the analysis of soil and crop samples. All farmers used more than one type of pesticide, most of whom used three types (73.7%). The most common was organophosphate (45.2%). Twelve of the identified pesticide brands were insecticides while the remaining two were fungicides. Twenty-three practiced cocktailing of pesticides (60.5%), mostly to save time. The most common PPE used while spraying pesticides were gas masks, gloves and boots. For the soil and crop samples, 3 soil samples were positive for Chlorpyrifos, two of which exceeded the maximum residue level (MRL). Of the 3 that were positive for Cypermethrin, all exceeded the MRL. Caution must be exercised when handling these potentially harmful pesticides. Proper equipment maintenance, cleaning and storage must be observed to prevent unnecessary pesticide exposure. Pesticide companies and the agricultural branches of the government must work towards adequate user education, focusing on safe handling of pesticides.
