The Green and Cost Effective Way to Improve the Indoor Air Quality (IAQ) 

改善室內空氣質素 (IAQ) 的綠色並且經濟有效的方法 

According to some researches and articles, Air Phytoremediation (AP) is an environmental remediation technology that uses green plants to remove the pollutants from polluted air. 

Some plants have the ability to assimilate, degrade, or modify toxic pollutants in air into less toxic ones, which makes it possible to remove the airborne pollutants via the AP technology. Some reports indicate that air pollutants can be effectively removed by plants. 

For example, Brassica species absorb SO2 and NO2 from polluted air and utilize it as a nutrient for their growth; Spinacia oleracea and Brassica oleracea uptake Cd, Sn, Zn, and Pb from air particulates through their leaves; Chenopodium murale removes volatile hydrocarbons; Zea mays removes phenolic compounds; and Zamioculcas zamiifolia removes Formaldehyde, etc. 

根據一些研究和文章，植物修復空氣方法（AP）是一種利用綠色植物去除污染空氣中污染物的環境修復技術。 

有些植物具有同化、降解或將空氣中的有毒污染物轉化為毒性較小的污染物的能力，這使透過AP技術去除空氣中的污染物成為可能辦法。一些報告表明，植物可以有效去除空氣污染物。 

 例如，蕓薹屬植物可從污染空氣中吸收二氧化硫和二氧化氮，並將其用作生長的養分；菠菜和甘藍透過葉子從空氣顆粒物中吸收鎘、錫、鋅和鉛；藜屬植物可去除揮發性碳氫化合物；玉米可去除酚類化合物；美鐵芋（金錢樹）可以去除甲醛，等等。
