植物能够通过光合作用吸入部分有害物质，但这类方法的作用极为有限。原因如下：
Plants can inhale some harmful substances through photosynthesis, but the effect of such methods is extremely limited. The reasons are as follows:
1、植物进行的是光合作用，一般在白天吸入部分有害物质，而在夜晚不具备这个功能。人的生活规律一般都是白天室外，夜晚在室内，在人最需要空气净化时，植物没有办法起到相应的作用。
1. Plants carry out photosynthesis, usually inhaling some harmful substances during the day, but not at night. The rule of human life is generally outdoor in the daytime, indoor at night, when people most need air purification, plants can not play a corresponding role.
2、植物吸收的有害物质极为有限。国家标准对甲醛的释放值要求低于0.08毫克/立方米，绝大部分刚装修完的房子，甲醛不低于0.2毫克/立方米 ，而吸收甲醛效率较高的绿萝，每小时吸收的甲醛仅为20微克。以一个100平米，房高3米，甲醛值为0.2毫克/立方米的房间来讲，同时需要1800盆绿萝，几乎要把整个房子空间添满，才能将甲醛降为0.08毫克，这还是在白天光线充足的情况下进行的、并且要保证在进行吸收的过程中不再有甲醛的释放。而事实上装修后的家具中甲醛还在一直不断释放。因此，植物仅能对甲醛、苯等有害物质起到辅助的治理作用。
2. The harmful substances absorbed by plants are extremely limited. The release value of formaldehyde required by national standards is less than 0.08 mg/cubic meter. Most newly decorated houses have no less than 0.2 mg/cubic meter of formaldehyde, while green radish with high formaldehyde absorption efficiency absorbs only 20 mg/h of formaldehyde. For a room with a height of 100 square meters, a height of 3 meters and a formaldehyde value of 0.2 mg/cubic meters, it also needs 1 800 pots of green radishes to fill up the whole house space, so that formaldehyde can be reduced to 0.08 mg. This is still done under the condition of sufficient daylight, and it is necessary to ensure that formaldehyde is no longer available in the process of absorption. Release. In fact, the formaldehyde in the furniture after decoration has been continuously released. Therefore, plants can only play an auxiliary role in controlling harmful substances such as formaldehyde and benzene.
