目的对乌鲁木齐市采暖期和非采暖期孕产妇和新生儿体内芳香烃受体的浓度进行检测,并分析其影响因素。方法分别于采暖期和非采暖期选取乌鲁木齐市孕产妇及新生儿各68对,采用酶联免疫吸附法对孕产妇和新生儿体内芳香烃受体浓度进行检测,并结合流行病学调查对其影响因素进行相关性分析。结果孕产妇和新生儿体内芳香烃受体浓度分别为(0.296±0.285)ng/mL和(0.150±0.122)ng/mL,且差异有统计学意义(P<0.05)。采暖期和非采暖期孕产妇和新生儿体内芳香烃受体浓度的差异均有统计学意义(P<0.01或P<0.05)。孕产妇体内芳香烃受体浓度与居住环境到马路的距离呈正相关,差异具有统计学意义(P<0.05),居住环境到马路的距离越近,芳香烃受体含量越高。结论孕产妇和新生儿体内芳香烃受体浓度有明显差异,燃煤和汽车尾气的排放是影响乌鲁木齐市孕产妇和新生儿体内芳香烃受体浓度的主要因素,也是乌鲁木齐市大气中多环芳烃的主要来源。
Objective To detect the concentrations of aromatic hydrocarbon receptors in pregnant women and newborns during the heating and non-heating periods in Urumqi and analyze the influencing factors. Methods 68 pairs of maternal and newborn infants in Urumchi were selected during heating period and non-heating period. The concentrations of aromatic hydrocarbon receptors in pregnant women and newborns were detected by enzyme-linked immunosorbent assay. Combined with epidemiological investigation, Factors affecting the correlation analysis. Results The concentrations of aromatic hydrocarbon receptors in pregnant women and newborns were (0.296 ± 0.285) ng / mL and (0.150 ± 0.122) ng / mL respectively, with statistical significance (P <0.05). There were significant differences in the concentrations of aromatic hydrocarbon receptors between pregnant women and neonates during both heating and non-heating periods (P <0.01 or P <0.05). There was a positive correlation between the concentration of aromatic hydrocarbon receptor in pregnant women and the distance from the living environment to the road, the difference was statistically significant (P <0.05). The closer the living environment was to the road, the higher the aromatic hydrocarbon receptor content. Conclusion The concentration of aromatic hydrocarbon receptors in pregnant women and newborns is obviously different. The emission of coal-fired and automobile tail gas is the main factor affecting the concentration of aromatic hydrocarbon receptors in pregnant women and newborns in Urumqi. It is also the main source of PAHs in the atmosphere of Urumqi. The main source.
