Abstract

In recent years, the problem of atmospheric particulate pollution has become more and more serious. Atmospheric fine particulate matter (PM_1.0) has a large specific surface area. PM_1.0 can carry a large number of metal elements into the depths of human lungs and blood circulation through the respiratory tract. In this paper, the PM_1.0 in autumn and winter in Harbin was taken as the research object. The mass and number concentration of PM_1.0 were analyzed. The metal elements in PM_1.0 were detected by inductively coupled plasma emission spectrometer (ICP-OES) and inductively coupled plasma mass spectrometry (ICP-MS). The top priority of this study was the source analysis of metal pollution in PM_1.0 using scanning electron microscopy (SEM) and positive matrix factor (PMF) method. It was found that the PM_1.0 number concentration was high in autumn and winter in Harbin. Particulate matter tended to accumulate and was not easy to settle due to the low temperature and relative humidity. In autumn and winter, combustion of fossil fuels such as coal and oil, soil dust and motor vehicle exhaust were the primary sources of PM_1.0.

哈尔滨市秋冬季大气细颗粒物（PM1.0）金属污染特征及来源分析

近年来，大气颗粒物污染问题日益严重。大气细颗粒物（PM1.0）具有较大的比表面积。PM1.0可携带大量金属元素通过呼吸道进入人体肺部深处和血液循环。本文以哈尔滨市秋冬季PM1.0为研究对象。分析PM1.0的质量和数目浓度。采用电感耦合等离子体发射光谱仪（ICP-OES）和电感耦合等离子体质谱法（ICP-MS）检测PM1.0中的金属元素。本研究的重点是利用扫描电镜（SEM）和正矩阵因子（PMF）法分析PM1.0中金属污染的来源。结果表明，哈尔滨市秋冬季PM1.0数值浓度较高。由于低温和相对湿度较低，颗粒物容易积聚，不易沉降。秋冬季节，煤、石油等化石燃料的燃烧、土壤粉尘和机动车尾气是PM1.0的主要来源。

期刊介绍： ASE is an international journal that publishes high-quality papers, communications, and discussion that advance aerosol science and engineering. Acceptable article forms include original research papers, review articles, letters, commentaries, news and views, research highlights, editorials, correspondence, and new-direction columns. ASE emphasizes the application of aerosol technology to both environmental and technical issues, and it provides a platform not only for basic research but also for industrial interests. We encourage scientists and researchers to submit papers that will advance our knowledge of aerosols and highlight new approaches for aerosol studies and new technologies for pollution control. ASE promotes cutting-edge studies of aerosol science and state-of-art instrumentation, but it is not limited to academic topics and instead aims to bridge the gap between basic science and industrial applications. ASE accepts papers covering a broad range of aerosol-related topics, including aerosol physical and chemical properties, composition, formation, transport and deposition, numerical simulation of air pollution incidents, chemical processes in the atmosphere, aerosol control technologies and industrial applications. In addition, ASE welcomes papers involving new and advanced methods and technologies that focus on aerosol pollution, sampling and analysis, including the invention and development of instrumentation, nanoparticle formation, nano technology, indoor and outdoor air quality monitoring, air pollution control, and air pollution remediation and feasibility assessments.
