Abstract

During the summer of 1989 and the winter 1989-1990, we initiated measurements of 1,1,1-trichloroethane concentrations in indoor, outdoor, and 'personal' air, in urban and rural sites. In the Piedmont region (North-Western Italy) we have carried out an atmospheric monitoring study: in the centre of Turin city (urban site), in Cuorgnè (rural site), and in Banchetta (remote site). First results confirm a higher winter contamination (11.67 vs. 2.79 micrograms/m3) and a higher contamination at the urban site, compared to rural and remote sites. Excluding Cuorgnè in the summer, all indoor/outdoor ratios are greater than 1 and, in all cases, the 'personal' air shows higher 1,1,1-trichloroethane levels than indoor and outdoor air. In Turin the relationships between winter and summer all show a higher winter contamination, while, in Cuorgnè no differences are proven.

摘要

在1989年夏季以及1989 - 1990年冬季，我们开始在城市和农村地区的室内、室外及“个人”空气中测量1,1,1 - 三氯乙烷的浓度。在皮埃蒙特地区（意大利西北部），我们开展了一项大气监测研究：在都灵市中心（城市站点）、库尔涅（农村站点）和班切塔（偏远站点）。初步结果证实，与农村和偏远站点相比，冬季污染更严重（11.67微克/立方米对2.79微克/立方米），且城市站点污染更严重。除夏季的库尔涅外，所有室内/室外比率均大于1，并且在所有情况下，“个人”空气中的1,1,1 - 三氯乙烷水平均高于室内和室外空气。在都灵，冬季和夏季之间的关系均显示冬季污染更严重，而在库尔涅，未证实存在差异。
