摘 要:目的:探讨可吸入颗粒物(PM10)对人体免疫学指标的影响。方法:根据河南省环境保护局提供的2002年至2004年大气PM10监测资料,选定PM10污染区和对照区,随机选择2地区成年居民各90名,采用放射免疫法测定血清白细胞介素-6(IL-6)、白细胞介素-8(IL-8)、肿瘤坏死因子(TNF)水平;采用ELISA方法测量2地区居民血清干扰素-γ(IFN-γ)水平。结果:PM10污染区居民血清IL-6((446.52±59.80)ng/L)水平高于对照区((56.34±9.13)ng/L)(P<0.05);污染区居民血清IL-8((0.31±0.17)μg/L)水平高于对照区((0.09±0.03)μg/L)(P<0.05);污染区居民血清TNF((0.46±0.34)μg/L)水平高于对照区((0.16±0.08)μg/L)(P<0.05);污染区居民血清IFN-γ((18.65±1.83)ng/L)水平低于对照区((20.37±0.86)ng/L)(P<0.05)。结论:PM10可对暴露人群机体免疫系统产生影响。Aim : To study the effect of PM10 on human immunological parameters. Methods :Selecting the polluted area and the control area based on the monitoring data of PM10 from year 2002 to 2004 by Henan Environmental Protection Bureau. A total of 180 residents were chosen equally from these two areas. The interleukin-6 (IL-6) , interleukin-8 (IL-8) and tumor necrosis factor(TNF) levels in serum from the 180 residents were determined using radio-immunity. The interferon-γ(INF-γ) level in serum from the 180 residents was determined using ELISA. Results: The IL-6 level in serum from the inhabitant of polluted area ( (446.52 ±59.80) ng/L) was higher than that from the control area( (56.34 ±9.13) ng/ L) (P 〈0.05) ; the IL-8 level in serum from the inhabitant of polluted area ( (0.31 ±0.17) μg/L) was higher than that from the control area ( (0.09 ±0.03) μg/L) (P 〈0.05) ;the TNF level in serum from the inhabitant of polluted area ( ( 0.46 ± 0.34 ) μg/L) was higher than that from the control area ( (0.16 ± 0.08 ) μg/L) ( P 〈 0.05 ) ; the IFN-γ level in serum from the inhabitant of polluted area (( 18.65 ± 1.83) ng/L) was lower than that from the control area ((20.37 ± 0.86) μg/L) (P 〈 0.05 ). Conclusion There were impacts on human's immune system exposed to PM10.
