Know The Air Pollution And Effects On Health



As the our environment becomes hot and more Populated , our vehicles engines are continue pumping dirty emissions, and half the world does not have access to clean air, we breathe in Dangerously polluting air. Ten out of nine people now breathe polluted air, which kills 7 million people every year. Health effects of air pollution are serious one-third of deaths due to stroke, lung cancer, and cardiovascular disease are due to air pollution.
It is difficult to avoid air pollution, it does not matter in which areas you live. air pollution are all around us. Microscopic pollutants in the air can damage our body, we can penetrate deep in our respiratory and circulatory system, which harm our lungs, heart and brain.
The lack of visible haze is not an indication that the air is healthy, in  both cities and villages are watching toxic pollutants in the air more than the average annual values recommended by the WHO's air quality guidelines. In order to help people understand better that the air is polluted, the WHO, the United Nations Environment and Climate and the Clean Life Alliance's breathing life campaign have developed online pollution meters.
There are two main types of air pollution - external air pollution due to various types of factories, vehicles engines smoke generation and  indoor air pollution refers to pollution generated by domestic combustion of fuel (due to burning like coal, wood or kerosene), open fire or bad Basic stove in ventilated places. Indoor and outdoor air pollution can contribute to pollution air.

Domestic air pollution kills 4 million people annually and affects countries in Africa and Asia, where pollution fuels and old air pollution technologies are used everyday for cooking, heating and lighting. Women and children, who spend more time inside the house, are most affected.

Major pollutants:  particle are mixture of solid and liquid droplets produced from fuel combustion and road traffic;  Nitrogen dioxide from road traffic or indoor gas cookers; sulfur dioxide by burning fossil fuels; And  ozone is caused by the reaction of sunlight with pollutant from ground emissions, at ground level. Pollutants that affect the people most are particle matter often PM is summarized and used as a remedy for air pollution.
particles with a diameter of 10 microns or less, (≤ PM10) can inhal deep inside the lungs,  even more health-damaging particles are those with a diameter of 2.5 microns or less, (≤ PM2.5). These particles are so small that combines 60 particles make up the width of a human hair. 
PM2.5 can goes inside the lung barrier and enter the blood system. They can increase the risk of heart and respiratory diseases, as well as lung cancer.
Ozone is a major factor to increase asthma  and nitrogen dioxide and sulfur dioxide can also cause asthma, bronchial symptoms, lung inflammation and reduced lung function. 
How can there be polluted air before affecting our health? For PM 2.5, WHO guidelines say the maximum safe level is an annual average concentration of 10 μg / m3 or less. To encourage cities to reduce air pollution, even if they are unable to meet the ideal safe levels, WHO has set three interim targets for the cities. These are: 15 μg / m3 (interim target 3); 25 μg / m3 (interim target 2); 35 μg / m3 (interim target 1). Many cities are now getting higher than the upper level of the interim target 1.

Air pollution has a devastating effect on children. Worldwide, up to 14% of children aged 5 to 18 have asthma associated with factors including air pollution. Every year, 543 000 children under 5 years of age die of respiratory disease related to air pollution. Air pollution is also associated with childhood cancer. Pregnant women are brought in contact with air pollution, this embryo can affect brain development. Air pollution is also associated with cognitive impairment in both children and adults.

As well as affecting our health, pollutants in the air are also causing chronic environmental damage by running climate change, which is a major threat to health and wellness itself.

This month, the United Nations Intergovernmental Panel on Climate Change warned that if we want to limit global warming to 1.5c, then the power taken out of coal should be eliminated by 2050. If not, we can only see a major climate crisis in 20 years.
