大气中苯并(a)芘容许浓度的研究

Study of Acceptable Concentration of BaP in Air

依据郑州地区大气中苯并(a)芘监测和肺癌标化死亡率调查,经相关回归分析,两者间存在高度正相关(r=0.97,P<0.01)得出回归方程y=3.94+5.57X。结合我国城市大气中苯并(a)芘污染情况和肺癌死亡率水平综合分析认为:大气中苯并(a)芘容许浓度以0.5～0.6μg/100m^3为宜。

Based on monitoring BaP concentration in air from urban districts of Zheng-zhou and surveying standardized death rate of Iung cancer, they are significant Positive correlation ( r = 0.97, P<0.01)and has regression equation y = 3.94 + 5.575x, by linear correlation and regression analysis. Combined BaP pollution in cities of China in air with level of death rate of lung cancer, it suggests by complicated analysis that it be appropriate 0.5-0.6μg/100m3 as acceptable concentration of BaP in air.
