大气氟污染的树木监测与评价

MONITORING AND ASSESSMENT OF FLUORINE POLLUTION BY PLANTS

本文介绍了采用植物监测与化学静态监测相结合方法,对上海某厂周围大气氟浓度和树叶含氟量进行测定,得出两者相关关系,确定悬铃木生长初期树叶含氟量划分大气氟污染等级指标,并运用生物学办法对影响区进行评价和浓度分区.

The concentration of fluorine in the air and the contents of it in the leaves around the factory of Shanghai were tested by the method which plant monitoring combined with chemical static monitoring.The correlation of them were got and the grade scale of atmospheric pollution of fluorine were determined by the fluorine contents in the leaves at the growing period of platane and by the biological method to assess the regional environment quality and to delimit the range of fluorine pollution according to the fluorine concentration.
