Air pollution statistics clearly show that air pollution is a major challenge being faced worldwide. There are many different effects of air pollution on the plants, animals and human beings.
There are varying causes of air pollution in all the countries on a global front. Industrial air pollution is the major contributor impacting the biological balance of the world. All the developed, developing and under developed countries are contributing in some or the other way for the air pollution. Global warming and melting of ice glaciers are the major impact on the environmental front due to air pollution.
Global air pollution data revolves around the Total Suspended Particles measured in micrograms per cubic meter, Sulfur Dioxide (SO2) measured in micrograms per cubic meter and Nitrogen Dioxide (NO2) measured in micrograms per cubic meter.
There are many government and non government organizations collating the air pollution data on a global front. The base of calculating air pollution is by measuring the above components in air and if they exceed the defined percentage then the air is termed to be polluted.
If any of the components penetration in the air increases above the said percentage the air in that country can be hazardous for the civilization.
The statistical data is published by World Health Organization (WHO) and also by the government. There is urban air monitoring sites established all over the globe to collect and collate the date on air pollution from time to time. Preventive measures are they designed and implemented by the government and environmental agencies to curb the polluting air particles.
World Health Organization (WHO) has standardized the annual guidelines for these air pollutants. According to the defined quality standard 50 micrograms per cubic meter for Sulfur Dioxide, 50 micrograms per cubic meter for Suspended Particles and 50 micrograms per cubic meter for Nitrogen Dioxide is permissible.
The air pollution statistics collected are tabulated in a central repository known as Healthy Cities Air Management Information System maintained by World Health Organization. The statistics are made available to all the reliable sources and based on the numbers appropriate preventive measures are designed to keep the safeguard plants, animals and mankind.
The data collected are verified number of times to prevent false information floating around. WHO has been doing the trend analysis and based on the reports recommending and identifying potential threat and the after effects if the preventive measures are not implemented.
