Air Quality Objectives Operating Stations QA/QC Trends

 

 

Introduction

    Air quality is important simply because we canít avoid breathing the air around us. The average adult breathes in about 20 cubic meters, or 20,000 liters of air a day. Other planets have sunlight, but only our earth has air and water. Without all of these there would be no life. A diverse community of plant and animal life has thrived on this planet for millions of years, sustained by the sun and supported by the soil, water and air.

    The air is made up of nitrogen and oxygen, with traces of other gases such as carbon dioxide, plus minute particles like dust. Although clean air should be freely available to all plant and animal life, humans have been gradually polluting it, putting their health at risk and the well-being of the earth itself.

    Air pollutants mainly come from the discharges of gases and particles mainly from industry, motor vehicles and Biomass combustion. There are also natural sources such as wind-blown dust and smoke from bush fires. Some forms of air pollution create global problems viz.,  upper atmosphere ozone depletion and acid rain. The enhanced greenhouse effect also falls into this category.

   The inhabitants of cities should be especially concerned, since they are exposed to a greater amount of pollutants coming from automobile traffic, commercial, industrial and manufacturing facilities, as well as other sources. Increased levels of air pollution are affecting the well being of inhabitants and imposing not just a direct economic cost by impacting human health but also threatening long-term productivity (material and vegetation damage, quality of life, reduced tourism to the country, discourage foreign investment etc.).  

    Rapid industrial and economic growth of the developing countries in Asia has increased urbanization and population pressure on local and national governments to keep pace with urban environmental management systems to meet the needs of the expanding cities with numerous parameters for management. Air pollution abatement strategies, solid waste management plans,  supply of water and control of wastewater and sewerage systems are the essentials of environmental management. In this energy plays a crucial role in all development plans to enable a livable city. Therefore, urban governance is challenged with the rapid globalization and the need to provide basic amenities to the population.

    Policy makers are active in framing rules and regulations for the better management of air pollution thereby ensuring better air quality. Rules and regulations work well at institutional level but at the individual level awareness and conscientious is very important to effectively reduce the air pollution. 

    APPCB is assessing the ambient air quality in the state. A monitoring network with 60 ambient air quality-monitoring stations through out the state are placed to assess the changes in air quality. In addition to it in Hyderabad continuous ambient air quality monitoring station has been installed. Based on the results of these monitoring stations, the government of A.P has taken preventive measures to control air pollution from different sources. APPCB is monitoring the point source emissions regularly and directions to install / upgrade air pollution control equipment are given to the industries that are exceeding the standards.
