Abstract
Air quality management involves the determination of the relative contribution of current or future source emissions at receptor sites to ground level pollutant concentrations coupled with implementation of effective management plan to reduce emission level. From the last few decades, urban air pollution has become an inevitable issue for its possible consequences on public health. In order to manage the ambient air quality, there are several methodologies with each having some specific advantages and constrains. Improvement of ambient air quality involves the basic approaches like emission reduction at source level, conversion of pollutants to a less damaging compounds and sequestration of pollutants. However, in order to manage the air quality, application of ornamental plants may be considered a well alternative approach. Although, it may not be imperative to consider plants as a sole alternative for urban ambient air quality management, but certainly it may useful to manage air quality for a small confined area, especially in case of indoor air. This paper reviews the possible application of ornamental plants, which may be trees, shrubs or herbs for its possible applications to regulate air quality. Some selective plant species has also been recommended based on its air pollution tolerance index.
Highlights
Air pollution had spread around the world like an evil with rapid urbanization and industrialization, it has resulted in various health problems for man such as respiratory, cardiovascular and ophthalmic diseases (Brunekreef and Holgate, 2002; Miller et al, 2007; Nandasena, 2010; Giles et al, 2011; Gudmundsson, 2011; Jamrozik and Musk, 2011)
Ambient air pollution has become a matter of great concern, in mega cities and urban areas and rapid industrial development coupled with emission from transport sector are recognized as the prime sources
Sulphur dioxide is one of the atmospheric pollutants that played a vital role in designating the ambient air quality of a place, since its emission occurs from various industrial sources besides fossil fuel thermal power stations
Summary
Air pollution had spread around the world like an evil with rapid urbanization and industrialization, it has resulted in various health problems for man such as respiratory, cardiovascular and ophthalmic diseases (Brunekreef and Holgate, 2002; Miller et al, 2007; Nandasena, 2010; Giles et al, 2011; Gudmundsson, 2011; Jamrozik and Musk, 2011). Ambient air pollution has become a matter of great concern, in mega cities and urban areas and rapid industrial development coupled with emission from transport sector are recognized as the prime sources. Planting of shrub and tree is an effective and easy way for air pollution control and treatment of environment (Nugrahani et al, 2012). Scientific management of landscape techniques and selection of plant species has opened the doors to minimize the deleterious effects of air pollutions in these areas. The awareness of growing ornamental plants for improvement of air quality is lacking in developing countries like India and there is a complete neglect of air quality improvement planning in big cities and near the industrial areas across the country. In view of the above, this paper will find out the possibility of using ornamental plant as an alternative approach for the management of ambient air quality
