Overview on Attenuation of Industrial Air Pollution by Greenbelt
نویسنده
چکیده
Urban air pollution due to industrial emission and vehicular emission due to automobiles has aggravated the problem of environmental pollution. Plants are known to act as sink for air pollutants. Planting of trees and shrubs in the form of greenbelt around the industry is an effective way for abatement of pollution and improvement of environment and is well recognized throughout the world. This article provides a brief review of the history and evolution of work on greenbelt development for pollution attenuation in an industry. It also reviews work on different aspects of greenbelt design and selection of plant species, which can be grown around industrial/urban areas in India. A reported case study carried out at petroleum refinery is discussed. At this plant, green belt of 500m width was found to be 36-40% efficient in removal of SO2, NOx & SPM and 84-94% efficient in removal of THC, VOC & CO. The future line of work is suggested for collecting data on the potential of greenbelts in attenuating the pollutants. Jr. of Industrial Pollution Control 24 (1)(2008) pp 1-8

Mathematical Modeling for the Design of Greenbelts for Air Pollution Control: An Engineering Perspective
Extensive research has also been done on the pollution attenuation capability of different tree species [2-5].But, in comparison, much less is known on how to maximize gains from a greenbelt. The normal proactive is to put a circular ring of trees around a pollution source. But it is easy to see that such an approach is likely to have limited utility, if at all. This is because dispersion of pa...
متن کاملTHE EFFECTS OF CUTTING ENERGY CONSUMPTION SUBSIDIES ON INDUSTRIAL AIR POLLUTION IN IRAN
Air pollution is an example of a negative externality; it imposes harmful effects and costs on people other than polluterS. In controlling air pollution, efficiency argument implies that, there is a rolefor the government to play. Studies show that taxation of fuels can be a powerful indirect instrumentfor controlling air polluticn because of the association between fuels use and emissions. In ...

In large-scale emergency, the vehicle routing problem focuses on finding the best routes for vehicles. The equitable distribution has a vital role in this problem to decrease the number of death and save people's lives. In addition to this, air pollution is a threat to people’s life and it can be considered to omit other kinds of disasters happens because of it. So, a new MINLP model presented ...

There is currently scarce information on the occurrence and distributions of Polycyclic Aromatic Hydrocarbons (PAHs) in the air from industrial estates in Nigeria. Hence, the present study aims to evaluate the extent and sources of pollution of polycyclic aromatic hydrocarbons in the air from some industrial estates in Lagos and Ogun States, Nigeria. Ten air samples have been collected from the...
متن کاملTolerance of Plants to Air Pollution in the Industrial Complex of Glass, Khak-e-Chini, Tile and Ceramics in Ardakan, Iran
Background and Aim: Air Pollution Tolerance Index (APTI), as a criterion for assessing plants' resistance to air pollution, is one of the important tools for managing air quality around industrial complex buildings. The aim of this study was to determine air quality and the APTI of native plants grown around the Industrial Complex of Glass, Khak-e-chini, Tile and Ceramics and Glass in Ardakan, ...
