世界上超过四分之一的人口依赖于基于燃料的照明。白炽灯通常位于用户附近，可能会增加呼吸道疾病和肺癌的风险。在文献中已经广泛地研究了由炉灶产生的颗粒物浓度。然而，表征的颗粒物浓度从燃料为基础的照明受到了最小的关注。这项研究表明，在高空气交换市场售货亭中使用单个简单灯芯灯的供应商可能会暴露于比环境健康指南高一个数量级的PM2.5浓度。与使用简单的灯芯灯相比，使用飓风灯将减少PM2.5和PM10浓度的暴露量。使用单个飓风灯或压力灯的供应商可能不会超过PM2.5和PM10的健康标准或指南，但会暴露于0.02-0.3 μ m的颗粒浓度升高。供应商从基于燃料的照明改为电力照明技术以增强照明可能会获得减少颗粒物暴露的辅助健康益处。仅暴露于环境和基于燃料的照明颗粒物的供应商，如果他们从简单的灯芯灯切换到电照明技术，吸入的PM2.5质量将减少80%以上。
Over one-quarter of the world's population relies on fuel-based lighting. Kerosene lamps are often located in close proximity to users, potentially increasing the risk for respiratory illnesses and lung cancer. Particulate matter concentrations resulting from cook stoves have been extensively studied in the literature. However, characterization of particulate concentrations from fuel-based lighting has received minimal attention. This research demonstrates that vendors who use a single simple wick lamp in high-air-exchange market kiosks will likely be exposed to PM2.5 concentrations that are an order of magnitude greater than ambient health guidelines. Using a hurricane lamp will reduce exposure to PM2.5 and PM10 concentrations by an order of magnitude compared to using a simple wick lamp. Vendors using a single hurricane or pressure lamp may not exceed health standards or guidelines for PM2.5 and PM10, but will be exposed to elevated 0.02-0.3 mu m particle concentrations. Vendors who change from fuel-based lighting to electric lighting technology for enhanced illumination will likely gain the ancillary health benefit of reduced particulate matter exposure. Vendors exposed only to ambient and fuel-based lighting particulate matter would see over an 80% reduction in inhaled PM2.5 mass if they switched from a simple wick lamp to an electric lighting technology.
