Abstract

Abstract: In this paper , pollutions of automobile emission in three st reet s were monitored and DNA damage effect s of particle ext ract s were studied with sister chromatid exchangs (SCE) test in peripheral blood lymphocytes. The result demonst rated that concent rations of TSP , NOx ,SO2 , CO and Pb were interrelated with the density of motors and the situation of roads and driving status. The f requencies of SCE of particles at different st reet were increased markedly ( P < 0.05) with dose2response relationship. Min Zhu Xi Lu was the highest , then Pan Xuan Lu and Nan Guan Shizi the lowest . It also indicates that automobile emisssion pollution of this city has been very serious and may have potent carcinogen.

Key words: Automobile emission, Particle ext ract s, SCE, DNA damage
