Due to the development of new city, more and more high buildings are constructed in the new cities. Traffic emission, high population density are also the factors to produce air pollution and to make the air quality getting worse. There are many atmospheric aerosols came from natural and human activities. Particle size is a key influence factor on discussing human health. Therefore, this study is conducted to investigate the particle distribution on different height and the results will be taken to consider the living floor in regard of the health consideration.
The instruments used in this study including Grimm1.108, PAS 2200 CE, AE51, Discmini, TSI-7545, HOBO for monitoring particles at different heights. The data was managed with Microsoft Office Excel 2003, and that is also taken for data analysis and to calculate the health of risk assessment of PM2.5 and PAHs exposure. The statistical software, JMP 5 and STATISTICA 7.1 are also used for statistical analysis.
In winter, PM10, PM2.5 and PM1 concentrations ranged as 5F> 2F> 8F, as well as Nano PM concentrations are 2F>8F>5F; BC concentrations are 8F>5F; PAH concentrations are 2F>5F>8F. In summer, PM10, PM2.5 and PM1 concentrations ranged as 2F> 5F> 8F, as well as Nano PM concentrations are 2F>8F>5F; BC concentrations are 2F>5F=8F; PAH concentrations are 8F>5F.
On different floors, the health risk of PM2.5 exposure based on PM2.5 concentrations and epidemiological study showed the highest mortality of lung cancer in residents living on 5F as compared to whom living on 2F and 8F in winter. In summer, the highest mortality of lung cancer in residents living on 2F. The residents living on 8F may have lowest mortality of lung cancer both in summer and in winter, and the residents living on 8F may have longest life as compared to those living on 2F and 5F. In winter, the cancer risk of PAH exposure on different floors showed 8F(1.31×10-6)>5F(1.23×10-6)>2F(1.21×10-6), as well as those data in summer also showed the similar trend, 8F(1.25×10-6)>5F(1.08×10-6). Although the cancer risk are all in acceptable range (10-4-10-6), but the residents living on the high floor exposed to higher cancer risk.
The current study showed that there is different distribution of particle concentrations on alternative floors. The particle size is very important in discussing the health impact of particles exposure. Therefore, the exposure assessment of particle concentration with alternative size and the component of particle content on the higher vertical height should be further investigated in discussing the residential height in this regard.
