Indoor Fine Particle Pollution in High-Rise Apartments in Hanoi
Main Article Content
Abstract
The study focuses on clarifying the fluctuations of indoor fine particle concentrations under different conditions and identifying the main factors contributing to this exposure. The light scattering method (by using ATMOtube real-time monitor) was evaluate by comparing it with the gravimetric reference method (by using MiniVol TAS 5.0 for sampling and weighing under our Lab conditions). The two methods were first tested according to standard procedures to ensure its stability and accuracy, next implemented simultaneously for comparison, and then the light scattering method was applied to 14 apartments in Hanoi for 24 hours, recording PM2.5 and PM10 concentrations. The research results show that: 1) PM2.5 and PM10 concentrations are similar, proving that the indoor particulate matter is mainly PM2.5; 2) the levels of fine particle PM2.5 pollution in high-rise apartments in Hanoi is at alarming levels, which are much higher than the WHO recommended levels. The main influencing factors such as residential area location associated with outdoor environmental conditions (density of traffic and construction activities), living habits (opening windows, smoking, using gas stoves), and the presence of fine particle reduction equipment were carefully analysed. The study results also demonstrate the effectiveness of using air purifiers in controlling indoor fine particle, helping to maintain a more stable environment during the day and night.
