摘要
世界上约91%的人口生活在空气污染的环境中,环境污染已成为人们普遍关注的问题。对城市室内外空气污染进行了充分的研究,并提出了有效的控制措施。然而,农村地区的空气污染问题还没有深入探讨。与城市大气污染相比,农村大气污染问题更为复杂和紧迫。东北农村受气候因素和经济条件的影响,供暖期间大部分家庭使用生物质秸秆、煤炭等固体燃料作为生活能源,总悬浮颗粒物(TSP)和多环芳烃(PAHs)污染严重。为了研究东北农村采暖期和非采暖期室内和室外TSP中多环芳烃的污染特征,采用中型颗粒物收集器1108A采集7 d TSP,并采用气相色谱-质谱法检测多环芳烃。结果表明:采暖期室内TSP和PAHs污染水平最高;通过诊断比(DR)和主成分分析(PCA)对多环芳烃源进行分析,发现主要污染源为生物质和煤炭燃烧、机动车排放和生活垃圾焚烧。根据致癌风险模型计算结果,东北农村生活区存在潜在的致癌风险。本研究反映了东北农村采暖期和非采暖期室内外TSP和多环芳烃的污染特征及来源,为进一步防治农村大气污染提供参考,有利于改善居住环境,提高人体健康水平。
Characteristics of indoor and outdoor Polycyclic Aromatic Hydrocarbons (PAHs) pollution in TSP in rural Northeast China: A case study of heating and non-heating periods
Approximately 91% of the world’s population lives in an air-polluted environment, and environmental pollution has become a widespread concern. Urban indoor and outdoor air pollution has been fully researched and effective control measures have been proposed. However, the issue of air pollution in rural areas has not been explored in depth. Compared to urban air pollution, the rural air pollution problem is more complex and urgent. Due to climatic factors and economic conditions in rural Northeast China, most households use solid fuels such as biomass straw and coal as domestic energy during the heating period, which will cause serious pollution problems of Total Suspended Particulate (TSP) and Polycyclic Aromatic Hydrocarbons (PAHs). To investigate the pollution characteristics of PAHs in indoor and outdoor TSP in rural Northeast China during the heating and non-heating periods, a medium-sized particulate matter collector 1108A was used to collect TSP for 7 days, and GC-MS was used to detect PAHs. The results showed that indoor TSP and PAHs pollution levels were the highest during the heating period. PAHs source analysis by Diagnostic Ratio (DR) and Principal Component Analysis (PCA) indicated that the main sources were biomass and coal combustion, vehicle emissions, and domestic waste incineration. According to the results of carcinogenic risk model calculations, there is a potential carcinogenic risk to the population in the Northeast rural living area. This study reflects the pollution characteristics and sources of indoor and outdoor TSP and PAHs in rural Northeast China during heating and non-heating periods, and provides a reference for further prevention and control of air pollution in rural areas, which is conducive to improving the living environment and improving human health.
