Understanding Air Pollution
According to the American Lung Association, Air pollution is a pressing environmental issue that affects the quality of the air we breathe. It refers to harmful substances in the atmosphere that can harm human health and the environment. Understanding the various air pollutants and their sources is essential in comprehending the risks associated with hiking in polluted areas.
Definition of Air Pollution
Air pollution refers to substances in the atmosphere that can negatively affect humans and the environment. These substances can exist as solid particles, liquid droplets, or gases, often forming aerosol dispersed and carried by gases. It’s important to note that pollutants can originate from either natural or man-made sources.
When categorizing pollutants, they are typically classified as either primary or secondary. Primary pollutants are usually generated through volcanic eruptions, resulting in ash release. Examples of primary pollutants include carbon monoxide gas emitted from vehicle exhausts and sulfur dioxide produced by factories. On the other hand, secondary pollutants are not directly emitted.
Air pollution is contamination by harmful substances, including gases, particulate matter, and biological molecules. These pollutants can arise from human activities and natural processes, contributing to poor air quality and health hazards to living beings.
Hiking In Bad Air Quality ─ Common Air Pollutants dangerous for lung health
Here are some of the most common air pollutants:
Particulate Matter (PM)
Particulate matter refers to tiny particles suspended in the air, varying in size and composition. PM2.5 and PM10 are the most concerning, with diameters less than 2.5 and 10 micrometres, respectively. PM2.5 can penetrate the respiratory system and even enter the bloodstream, causing health issues. PM sources include vehicle emissions, industrial processes, construction activities, and wildfires.
Nitrogen Dioxide (NO2)
Nitrogen dioxide is a reddish-brown gas that forms when nitrogen oxides (NOx) react with the air. Major sources of NO2 are combustion processes in vehicles, power plants, and industrial facilities. High levels of NO2 can irritate the respiratory system and worsen respiratory conditions.
Ozone (O3)
Ozone, a gas composed of three oxygen atoms, exists in two distinct layers of the atmosphere. While ground-level ozone is considered a secondary pollutant, it forms due to the reaction between volatile organic compounds (VOCs) and nitrogen oxides in the presence of sunlight. This ground-level ozone plays a significant role in smog formation and can adversely affect respiratory health when inhaled in high concentrations.
Sulfur Dioxide (SO2)
Sulfur dioxide is a colorless gas with a pungent odor. It is primarily produced by burning fossil fuels containing sulfur, such as coal and oil, in power plants and industrial processes. Breathing in SO2 can lead to respiratory issues and aggravate existing respiratory conditions.
Carbon Monoxide (CO)
Carbon monoxide is a colorless, odorless gas produced by incomplete combustion of fossil fuels. It binds to haemoglobin in the blood, reducing its ability to carry oxygen, and can lead to headaches, dizziness, and even death at high concentrations. Major sources of CO include vehicle emissions and residential heating.
