大气污染对儿童唾液溶菌酶含量的影响

EFFECT OF AIR POLLUTION TO CHILDREN'S SALIVARY LYSOZYME

本文分析了重庆市大气污染(SO_2、NO_x、TSP)的特征,报导重污染区儿童唾液溶菌酶含量明显低于相对污染区(P<0.00001),污染区儿童体内免疫功能下降;发现暴露于两种或两种以上因素(酸沉降物、被动吸烟、燃煤)时,对儿童唾液溶菌酶含量的影响远大于它们单一因素的作用(P<0.00001),经逐步回归分析,得Y=401.6869-68.1306X_5-42.3868X_1-20.8466X_4(r=0.7681,F值=185.08,P<0.00001);并针对重庆市大气污染的具体情况,提出一些有意义的建议措施。

In this report, we have investigated the characteristics of air pollutants (Ⅰ.Sulfur dioxide; Ⅱ. Nitrogen oxides; Ⅲ. Total suspended particulates). Children's salivary lysozyme levels in pollated area were much lower than those in relative polluted area (p<0.00001), and childorn's immunoeompetences in polluted area were declining. When children exposed to two or above two factors, for example: air acid deposition, passrve smoking, fuel type etc., their effects were much larger than single factor (P<0.00001). By stepwise regrassion analysis, we have gained a regrassion equatign, 1. e. Y=401. 6889-68. 1306x_5-42. 3888x; -20.8466x_4(R=0.7681, F=185.08, P<0.00001). On the basis of air pollutant characteristics in Chongqing city, we put forward somerationalization proposals.
