在大气污染物中,二氧化硫是当前最主要的一种。它大量来自交通运输业、民间燃料以及某些工矿企业如硫酸厂、制药厂等生产过程中排放出的废气。因此,它的数量最多,分布最广,危害最大。通过各种措施首先对二氧化硫进行治理,是环境保护的当务之急。本试验的目的就是以生物防治措施为出发点,选择适合于以二氧化硫为主的大气污染区绿化的净化树种。一、试验材料与方法植物主要是通过叶片吸收大气中的二氧化硫,所以我们测定植物对二氧化硫的吸收能力
In the air pollutants, sulfur dioxide is the most important one. It comes from a large number of emissions from the transport industry, private fuels and some industrial and mining enterprises such as sulfuric acid plants, pharmaceuticals and other emissions from the production process. Therefore, it is the largest number, the most widely distributed and the most harmful. Through various measures to treat sulfur dioxide first, it is imperative for environmental protection. The purpose of this experiment is to take biological control measures as the starting point and select the purification tree suitable for the greening of the air pollution area mainly containing sulfur dioxide. First, the test materials and methods Plants mainly through the leaves to absorb sulfur dioxide in the atmosphere, so we determine the plant’s ability to absorb sulfur dioxide
