๐ What Gases We Breathe In and Out: The Science of Every Breath We Take ๐ฌ️ Introduction: The Breath of Life We breathe in air, a nutritious mixture of invisible gases that keep us alive. None of us, though, pauses to think about what we are breathing. Instead of being simply "oxygen," air is a remarkable and complex mixture of gases that have evolved over millions of years as a result of industrialization, the emergence of plants, and, most recently, pollution in the modern world. This blog will examine the actual composition of the air we breathe, its historical changes, the gases we breathe in and out, and the reasons why breathing is both a scientific marvel and a cause for concern regarding the environment. ๐ The Air We Breathe: A Historical Context ๐ฐ️ The Antiquity of Air The four classical elements—earth, air, fire, and water—were based on a philosophical idea before we were aware of the chemical characteristics of air. Then, through experimentation and obser...
The Air quality rate of every country is growing very fast. We need oxygen to breathe; without oxygen, we cannot exist anymore. The WHO, the World Health Organization, is also conscious of this matter and takes the same meaningful action to tackle this impurity. Reasons Why It's Growing Fast 1. Industrial Emissions Industries play an important role in air pollution. Factories, power plants, and refineries release many harmful substances into the atmosphere, including sulfur dioxide, nitrogen oxide, and particulate matter. These emissions are by-products of manufacturing processes, fossil fuel burning, and chemical production. The concentration of pollutants around industrial areas can be extremely high, making them major contributors to poor air quality, especially in urban areas. 2. Increase in Vehicle Usage The global rise in urbanization has led to an increase in the number of vehicles on the roads. Cars, trucks, and buses emit carbon monoxide (CO), nitrogen ...
