Methane, known chemically as CH4, is a gas that is harmful to the atmosphere and to living beings because it has a high heat-trapping capacity. For this reason, it is the second largest contributor to the greenhouse effect after carbon dioxide (CO2). It is a simple...
Ozone (O3) is a gas whose function and impact on the environment depend on the atmospheric layer in which it is found. To understand the danger of ground-level ozone, it is essential to first distinguish between its two main variants. Tropospheric ozone shares its...
Nitrogen dioxide (NO2) is a harmful gas whose presence in the atmosphere is mainly due to the use of fossil fuels in combustion vehicles and industrial activities. This chemical compound, formed by the combination of nitrogen and oxygen, can have serious consequences...
Atmospheric conditions are essential to prevent damage to human health and to reduce the causes of increased mortality or serious effects of exposure to poor air quality. Air pollutants are also linked to the environmental degradation of terrestrial and aquatic...
Measuring air quality is essential for improving human and environmental health. Changes in the natural composition of the air we breathe are common in industrialised societies, where most of the world’s population lives. Action to eliminate or at least minimise...
