Do you know in a Bulletin of WMO they have stated that \u201cAir Quality and climate change must be tackled together.\u201d (World Meteorological Organization) Hence, there is interrelation between heatwaves and air pollution. Eventually, it leads to an increase in air pollution. And the foremost reason behind it is the rise in global temperatures. Every day, it is setting new alarming records. <\/p>\n\n\n\n

You must be wondering how heatwaves can result in air pollution<\/a>. Hence, here is the answer! Heatwaves worsen the atmospheric conditions that lead to emission of various pollutants. Including ground-level ozone and particulate matter. These are major air pollutants that react with heat and form more pollutants. Do you know how ozone exposure can affect your health? Considering, it is a harmful pollutant that can be life-threatening for long-term inhalation. <\/p>\n\n\n\n

In this article, you can learn about it in details and impacts on human health. Furthermore, you can also check for the potential solution for mitigating the effects. <\/p>\n\n\n\n

How do heat waves influence air pollu<\/strong>t<\/strong>ion?<\/strong><\/strong><\/h2>\n\n\n\n

Have you ever wondered why there is high pollution <\/a>during high temperatures? Well, there are many scientific reasons behind it. Since, it can be influenced due to various reasons such as atmospheric conditions and human activities. Therefore, checkout the following points to know the actual reason: <\/p>\n\n\n\n

<\/p>\n\n\n\n

\"Heatwaves<\/figure>\n\n\n\n

1. Temperature: <\/strong><\/h4>\n\n\n\n

Heatwaves increase the earth’s surface temperature.<\/a> In result, the rising temperature traps the cooler air and holds the pollutants in the atmosphere. <\/p>\n\n\n\n

2. Rise in Emissions:<\/strong><\/h4>\n\n\n\n

Do you know heatwaves <\/a>increase the emission from different sources? It is the reality that as the temperature rises it increases the demand for Air conditioners and other cooling devices in every industry. As a result, it leads to higher emissions from power generation. <\/p>\n\n\n\n

3. Secondary pollutants: <\/strong><\/h4>\n\n\n\n

Heatwaves result in chemical reactions that contribute to secondary pollutants formation. The reactions take place due to high temperature. Consequently, it results in O3 at ground level. <\/p>\n\n\n\n

4. Increase in fires: <\/strong><\/h4>\n\n\n\n

Heatwaves lead to a rise in wildfires and fires as it plays the role of fuel (NIH). Due to this, it emits various pollutants including particulate matter and carbon monoxide. <\/p>\n\n\n\n

What pollutants are emitted in the atmosphere due to heatwaves?<\/strong><\/strong><\/h2>\n\n\n\n

Air quality includes numerous pollutants that can increase during high temperatures. It includes PM2.5, PM10, NO2, SO2, CO, O3 and other pollutants. In extreme heatwaves, ground-level ozone and particulate matter are the major pollutants. <\/p>\n\n\n\n

Chemical reaction: <\/strong><\/h4>\n\n\n
\n
\"Chemical<\/figure>\n<\/div>\n\n\n

<\/p>\n\n\n\n

Since intense sunlight increases the photochemical reaction that leads to ground-level ozone emission. With it, it can also result in releasing of nitrogen oxides (NOx) and volatile organic compounds (VOCs). <\/p>\n\n\n\n

<\/p>\n\n\n\n

Wildfires: <\/strong><\/h4>\n\n\n
\n
\"Wildfire<\/figure>\n<\/div>\n\n\n

<\/p>\n\n\n\n

Moreover, as you already know heatwaves cause wildfires<\/a>. Hence, it is the main source of various pollutants. It releases a major amount of PM and VOCs. Besides, it greatly affects the overall geographical environment. <\/p>\n\n\n\n

 <\/h4>\n

Power plants: <\/strong><\/h4>\n\n\n
\n
\"emission<\/figure>\n<\/div>\n\n\n

<\/p>\n\n\n\n

The temperature rise also increases the energy demands. Thus, the energy demands spike more emissions from power plants. Therefore, these contribute to carbon dioxide, sulfur dioxide and nitrogen oxides. <\/p>\n\n\n\n

<\/p>\n\n\n\n

Vehicles:<\/strong><\/h4>\n\n\n
\n
\"Emission<\/figure>\n<\/div>\n\n\n

<\/p>\n\n\n\n

Furthermore, Vehicle usage increases in the heatwaves to avoid heat. Hence, it leads to more emissions from vehicles in urban areas. <\/p>\n\n\n\n\n\n

<\/div>\n\n\n\n

Do you know what you can face due to high ground-level\u00a0ozone?<\/strong><\/h3>\n\n\n\n

Ozone is the secondary pollutant that forms with NOx, VOCs and Sunlight reactions. It means you are also enhancing other pollutants including nitrogen oxide, and volatile organic compounds. Hence, an increase in temperature can lead to Ozone in the atmosphere. And long-term ozone inhaling leads to various respiratory issues. High ozone exposure leads to premature death. With it, it also leads to immediate breathing conditions. Such as per American Lung Association:<\/p>\n\n\n\n
