Analysis of Harmful Heavy Metals and Carbonaceous Components in Urban School PM2.5
Harmful heavy metals and carbonaceous substances contained in PM 2.5 collected from 53 schools located in large Korean cities were closely analyzed based on the hypothesis that emission sources such as automobiles are coincident. The average concentration of PM 2.5 from the analysis of all classrooms was 20.7 µ g m – 3 . Mn was the most prevalent heavy metal with a concentration of 0.018 µ g m – 3 , followed by Pb and Cu. The heavy metals were closely related to elemental carbon (EC) introduced mainly from the outside with a correlation coefficient of 0.556, showing consistent significance. Organic carbon (OC) showed a correlation coefficient of 0.357, which statistically supported the presence of obvious OC sources in the classroom. Overall school classroom contamination levels have been shown to be below national guideline.

期刊介绍: The international journal of Aerosol and Air Quality Research (AAQR) covers all aspects of aerosol science and technology, atmospheric science and air quality related issues. It encompasses a multi-disciplinary field, including: - Aerosol, air quality, atmospheric chemistry and global change; - Air toxics (hazardous air pollutants (HAPs), persistent organic pollutants (POPs)) - Sources, control, transport and fate, human exposure; - Nanoparticle and nanotechnology; - Sources, combustion, thermal decomposition, emission, properties, behavior, formation, transport, deposition, measurement and analysis; - Effects on the environments; - Air quality and human health; - Bioaerosols; - Indoor air quality; - Energy and air pollution; - Pollution control technologies; - Invention and improvement of sampling instruments and technologies; - Optical/radiative properties and remote sensing; - Carbon dioxide emission, capture, storage and utilization; novel methods for the reduction of carbon dioxide emission; - Other topics related to aerosol and air quality.
