An overview of air pollution

 

World Pollution

    Air pollution is an ongoing crisis, and while we all recognize that there is a problem, the reality of the data is shocking. A commonly used measure of pollution levels is PM2.5, which measures the level of particulate matter of 2.5 microns or less present in air.

    A build-up of these particles has been shown to correlate with an increase in death caused by heart and lung disease by several major studies. In less severe cases, it can trigger many diseases such as bronchitis, asthma or heart problems.

    PM2.5 levels are measured in μg/m3 over a 24-hour period. A value under 12 means clean. Higher values, up to 35.4 represent a moderate risk that can cause respiratory issues for those sensitive to contaminates. Above 35.4 causes problems, with the higher the levels the more people who will find themselves being affected.

    Today, vast areas of the world, especially Asia and the Middle East, see PM2.5 levels above 35.4, that is, unhealthy for humans and animals. Many of those areas reach Hazardous levels, considered life threatening, on a regular basis.

    While this shows us the need for action, the reality is that these levels of pollution are rising, not falling, and for huge areas of the world, the problem is getting worse.

The effect of pollution

    It is estimated that over 1 million Chinese die every year from diseases caused, or made worse, by pollution. In addition, that pollution is costing the Chinese economy some 267 Billion Yuan every year, and that story is repeated around the world.

    Globally, pollution accounts for 10% of the total mortality rate for children under the age of five (click here to know more), and it kills an estimated 8 million people around the world every year.

    It is clear that we must take action, and Zero2.5 are committed to provide clean, fresh air, but a natural solution that takes on the global challenge.
