Key Points:

• Familiarizing yourself with basic air quality terms is essential for making informed decisions about your health and the environment.
• Particulate Matter (PM) and Volatile Organic Compounds (VOCs) are common inhalable pollutants that can cause severe respiratory and cardiovascular issues.
• Harmful gases like Sulfur Dioxide (SO2), Nitrogen Oxides (NOx), and ground-level Ozone are toxic byproducts of burning fossil fuels and chemical reactions that lead to smog and breathing problems.

What are the air quality terms you should know?

If you want to stay in the loop and make informed decisions about your health and exposure to harmful pollutants, you should learn basic air quality control terms. The list includes:

• Particulate Matter (PM) – it’s a type of airborne pollutant composed of tiny particles that can be inhaled. PM is divided into two categories: PM-10 (particles smaller than 10 micrometers) and PM-2.5 (particles smaller than 2.5 micrometers). These particles can cause respiratory and cardiovascular health problems.
• Volatile Organic Compounds – VOCs are a type of air pollutant that consists of a wide range of chemical compounds. Such compounds are emitted from sources such as industrial processes, vehicle exhaust, and consumer products like paint and cleaning supplies. VOCs can cause health problems such as eye and throat irritation, headaches, and nausea.
• Sulfur Dioxide – when learning about air quality terms, it’s crucial to take a closer look at SO2. This type of air pollutant is produced by burning coal and oil. The gas is highly reactive and can form a range of other air pollutants, such as sulfates and acid rain. SO2 can irritate the respiratory system and lead to breathing problems.

• Nitrogen Oxides – NOx is produced by burning fossil fuels and other sources. NOx can react with other compounds in the atmosphere and form ozone, which is a major component of smog. Additionally, NOx can contribute to acid rain and respiratory health problems.
• Ozone – if you want to add new air quality control terms to your glossary, you shouldn’t forget about this one. Ozone is a colorless, toxic gas composed of three oxygen atoms. It occurs naturally in the upper atmosphere, where it forms a protective layer that shields the Earth from the sun’s ultraviolet radiation, but it can also be produced in ground-level concentrations by chemical reactions involving air pollutants such as nitrogen oxides and volatile organic compounds.

The takeaway

Pollution is an important issue, and understanding the basics of air quality control terms is key to making informed decisions about your health and the environment.
