PM10 Measurement and Analysis of Urban Public Spaces Indoor Environment

Abstract

The content of PM10 and PM2.5 in public places can harm to human health. Conduct the PM10 measurement in three public places of Qinhuangdao Kindergarten, Office Building and College Classroom. According to the measurement data statistics, analysis the influencing factors of indoor environmental pollution. The results showed three conclusions. First, the indoor PM10 concentrations influenced by the indoor whether heating or not. The PM10 concentration change ratio is 1.12~ 1.663, and the PM2.5 concentration change ratio is 1.29~2.1. Secondly, in the fog haze weather, indoor PM10 concentrations linear associated with outdoor PM10 concentrations; in the sunny day, there was no obvious correlation with the outdoor PM10 concentrations. Finally, contrast the standard drawn up by domestic and foreign relevant organizations and authorities, in the fog haze weather, indoor PM10 and PM2.5 concentrations below China standard value, but higher than USA, Europe, Japan standard value.
