Impact on the Environment Impact on the Air Natural turf consists of green plants that absorb CO2 through photosynthesis, release oxygen and absorb toxic gases such as sulfur dioxide, hydrogen fluoride, ammonia and chlorine to clean the air Role. Natural lawn has obvious retarding effect on the dust. The measured data show that the dust concentration in the bare land is 13 times higher than that on the lawn when scraping 34 winds. Research shows that 25 square meters of lawn can be exhaled by a person all the absorption of carbon dioxide into oxygen to meet the human body required oxygen during the breathing process. Artificial turf is a non-living material made of polyethylene, polypropylene and other polymers, can not carry out the metabolism of green plants, it does not have the role of regulating the balance of carbon and oxygen in the atmosphere. Although artificial turf can block dust to a certain extent, it does not have the function of absorbing toxic gases to purify the atmosphere. In addition, the low level of artificial turf fiber often contain chlorine impurities, under high temperature and strong sunlight will decompose and release chlorine, damage air quality.
