随着工业和汽车交通运输的发展,许多地区大气中的铅污染有逐年增高的趋势,环境铅污染的危险性已引起各国重视。我国因汽车交通频繁而造成铅污染的情况尚不严重,全国大城市之一的上海,大气中铅的浓度仅1μg/m~3左右。为了探讨生活和生产环境空气中不同浓度的铅对人群的生物效应,为修订大气铅的卫生标准提供参考依据,我们在合肥市进行了调查。
With the development of industry and automobile transportation, the lead pollution in the atmosphere in many areas has been increasing year by year. The danger of environmental lead pollution has drawn the attention of all countries. Lead pollution caused by frequent car traffic in our country is not serious. One of the big cities in China, the concentration of lead in the atmosphere is only about 1μg / m ~ 3. In order to investigate the biological effects of different concentrations of lead in the air of living and production environments on the population, we provided a reference for revising the sanitary standards of atmospheric lead. We conducted a survey in Hefei.
