Objective:
To explore effects of airborne fine particulate matters on human immunological indicators.
Methods:
All subjects were measured the level of PM2. 5 individual exposure with personal sampling devices. Serum immunological indicators, such as WBC, NE, NE%, Ly, Ly%, CD4+, CD8+, CD4+ / CD8+, IgA, IgM, IgG and IgE were detected through enzyme-linked immunosorbent assay. Then, comparing the difference of PM2.5 exposure and immunological indicators between two groups.
Results:
For the level of PM2.5 daily exposure, traffic policemen (115.4 +/- 46.2) microg/m3) was significantly higher than residents ((74.9 +/- 40.1) +/- g/ m(-3)). And there was also significant difference in some immunological indicators, such as Ly%, CD4+, CD8+, IgM, IgG, IgE, CC 16 and CRP, between two groups.
Conclusion:
Long-term high level of airborne fine particulate matters exposure may change some blood immunological indicators, affect the health of the immune system.
