Indoor and outdoor relationships of particles with different sizes at an apartment in Ha Noi: mass concentration and respiratory dose estimation

Abstract

This paper presents data on the size distribution and concentration of particulate matters (PM₀,₁, PM₀,₅, PM₁, PM₂,₅, PM₁₀, TSP) in indoor and outdoor air at a residential apartment in two seasons (winter and summer) in Ha Noi, Viet Nam. These particles with different sizes were taken by 5 stage impactors (Nano sampler 3182, KINOMAX). Daily average concentrations of coarse particles (PM₁₀) and fine particles (PM₂,₅) indoors and outdoors exceeded the WHO recommended values. In winter, the concentrations of PM₀,₁, PM₀,₅, PM₁, PM₂,₅, PM₁₀ and TSP are higher than in summer. However, concentrations of PM₀,₁ (NP) remains negligible change between two seasons.
