ABSTRACT
Recently air pollution poses a serious threat on mankind all over the world by damaging different ecosystem process. The main polluting substances are sulfur oxides, nitrogen oxides, carbon oxides, ozone, particulate matter, and heavy metals that cause damage to the surrounding environment. Photosynthetic plants are the one and only natural barrier and buffer against air pollution. Herbs, shrubs, and trees all are responsible for cleaning air and greening environment by their internal microanatomy, physiology, and biochemistry. In an area where a large forestland was removed for big and many industrial setups, there a scientific plantation of well air pollution tolerated plant species will be the main strategy to overcome the air pollution problem. A large tree, may be Gymnosperm or Angiosperm, plays a good role to combat against air pollution by not only soak or metabolized the polluted gases but also it can reflect and precipitate the particulate matter. In this context, appropriate research work need to be designed an establishment of structural green belt by well air pollution tolerant plant species.102
