Current State of Indoor Air Phytoremediation Using Potted Plants and Green Walls

Urban civilization has a high impact on the environment and human health. The pollution level of indoor air can be 2–5 times higher than outdoor pollution, sometimes it reaches up to 100 or more in natural/mechanical ventilated buildings. Even though people spend about 90% their time indoors, importance quality is less noticed. Indoor treated with techniques such as chemical purification, ventilation, isolation, removing pollutions by plants (phytoremediation). Among these techniques, phytoremediation not given proper attention and, therefore, focus our review paper. Phytoremediation an affordable environmentally friendly means purify polluted air. Furthermore, studies show that used regulate building temperature, decrease noise levels, alleviate social stress.
