Green plants work as a 'natural pollutant sink' on earth intercepting dust and pollutants from air and water. During photosynthesis, plants absorb CO2 and other gases through their stomata. Plants also reduce air pollution by intercepting suspended particulate matters (SPM) and aerosols and retaining them on the leaf surface. This book presents new and significant research in the role of plants in protecting the environment.

Many industrial processes cause volatile organic and inorganic odorous compounds to be emitted in large quantities. These compounds create hazards to the ecosystem and to humans. Biotechnology offers one of the most economical and environmentally friendly methods for controlling odor and air pollution.
