- Abstract
Industrialization has provided humanity with materials and social benefits. It has also brought in its wake up many unwanted substances and social problems. One of these problems is the degradation of the environment. The environment, upon which our life is most dependent, has fallen victim of pollution brought by the man himself through unplanned and unscientific development and mineral exploitation. Air pollution is an inevitable harmful by-product of rapid industrialization and urbanization that is responsible for a variety of deleterious effects on both human and plant communities. It has been a major environmental concern since the beginning of industrialization, resulting in a release of gaseous and particulate pollutants into the atmosphere. A relationship between traffic density and photosynthetic activity, stomatal conductance, total chlorophyll content and leaf senescence has been reported. Exposure of evergreen plants to air pollutants create many changes in physiological and biochemical parameters. Each plant species has a different ability to absorb and adsorb pollutants by their foliar surfaces, which is influenced by several biochemical, physiological and morphological characteristics. Rampant and uncontrolled use of fossil fuels in industries and transport sector has led to an increase in concentrations of the gaseous pollutants. Indian cities are facing serious problems of airborne particulate matter. Atmospheric particulate matter, which is a mixture of diverse elements, is of most concern in context of public health. Particulates may also cause a reduction in yield, change in photosynthesis and transpiration along with foliar injuries. The plant species which accumulate more dust onto their surfaces can act as buffer around industries and along roadsides. The present study deals with the plant-pollutant interactions and how the physical and chemical characteristics of plants vary with air pollution. It also throws light on how dust affects various plant species and what is the role of plants in dust accumulation.
