植物对大气污染的表征

Characterization of Atmospheric Pollution of Plants

由于植物一定程度上可以吸附空气中的氟和硫,所以,合理种植抗污染性能强的植物种类,十分重要。本文对南通市5个点位的绿色植物体内的氟化物和硫化物进行了测定。结果表明,它们对大气中的污染物有很强的吸收和富集作用,秋季叶片中硫和氟污染物的含量高于春季,且与污染强度相吻合。研究污染物在植物体内的积累是监测和评价大气污染的十分有效的方法。

Green plants have the ability to absorb and accumulate fluorides and sulfides in the air, so it is very important to plant plants with strong anti-pollution performance in limited space of a city.In this paper, fluoride and sulfide in green plants of five places in Nantong City were determined.Results showed that green plants have strong absorption and accumulation ability of pollutants in the atmosphere.Leaves have higher sulfur and fluorine contents in autumn than in spring,which is consistent with the pollution intensity.Study of the accumulation of pollutants in plants is a very effective way for monitoring and evaluation of air pollution.
