Central ventilation and air conditioner systems are widely utilized nowadays in public places for air exchange and temperature control,which significantly influences the transfer of pollutants between indoors and *** study the effect of central ventilation and air conditioner systems on the concentration and health risk from airborne pollutants,a spatial and temporal survey was carried out using polycyclic aromatic hydrocarbons （PAHs） as agent *** the period when the central ventilation system operated without air conditioning （AC-off period）,concentrations of 2-4 ring PAHs in the model supermarket were dominated by outdoor levels,due to the good linearity between indoor air and outdoor air （rp〉0.769,p〈0.05）,and the slopes （1.2-4.54） indicated that ventilating like the model supermarket increased the potential health risks from low molecular weight *** the period when the central ventilation and air conditioner systems were working simultaneously （AC-on period）,although the total levels of PAHs were increased,the concentrations and percentage of the particulate PAHs indoors declined *** BaP equivalency （BaPeq） concentration indicated that utilization of air conditioning reduced the health risks from PAHs in the model supermarket.

目的调查上海市广州管圆线虫中间宿主螺类的种类、分布和感染现状。方法于2012年8月-2014年10月,在上海市嘉定、青浦、普陀、宝山、杨浦、闵行、松江、金山、崇明和浦东新区等10个区县现场开展了广州管圆线虫中间宿主螺类的调查。采用肺检法和匀浆法剖检采集的螺类,计算感染率。结果共采集螺类标本1 074只,经形态学鉴定,隶属于8科10种,其中小管福寿螺133只、褐云玛瑙螺25只、中国圆田螺183只、铜锈环棱螺78只、尖膀胱螺349只、椭圆萝卜螺224只、同型巴蜗牛45只、中华灰巴蜗牛32只、黄蛞蝓2只和双线嗜黏液蛞蝓3只。其中褐云玛瑙螺为市场销售,野外未见分布;而小管福寿螺在青浦区金泽镇发现野外自然种群。病原学检测未发现感染广州管圆线虫的螺类。结论上海地区未发现广州管圆线虫感染螺类,但对小管福寿螺应加强相应的监测工作。
