Pesticide Residues
Pesticide Residues Pesticide residues are small amounts of chemicals used in agriculture to control pests, which can remain on crops, in the soil, or evaporate into the air. These residues can potentially impact human health, causing a range of health issues such as respiratory problems, hormone disruption, and, in some cases, cancer, especially with prolonged…

Ozone
Ozone Ozone (O₃) is a gas formed in the atmosphere through chemical reactions between volatile organic compounds (VOCs) and nitrogen oxides (NOₓ) in the presence of sunlight. It plays a dual role in the environment: in the stratosphere, ozone forms the ozone layer, which protects life on Earth by absorbing harmful ultraviolet radiation. However, at…

Nitrogen Oxides
Nitrogen Oxides Nitrogen Oxides (NOx) is a group of reactive gases primarily composed of nitric oxide (NO), a colorless, odorless gas, and nitrogen dioxide (NO₂), a reddish-brown gas with a pungent odour. NO forms during high-temperature combustion processes and reacts with oxygen or ozone in the air to create NO₂. NOx contributes to air pollution,…

Sulfur oxides
Sulfur oxides Sulfur oxides (SOx), primarily sulfur dioxide (SO₂), are gases produced mainly by burning fossil fuels and certain industrial processes. They contribute to air pollution, acid rain, and respiratory issues when released into the atmosphere and can react with water vapor to form sulfuric acid, damaging ecosystems and infrastructure.

Forever chemicals
Forever chemicals “Forever chemicals” is a term used to refer to a category of human-made synthetic chemicals known as per- and polyfluoroalkyl substances (PFAS). PFAS are characterized by strong molecular bonds between carbon and fluorine atoms, making them highly resistant to degradation in the environment. PFAS can accumulate in nature and in human tissues, raising…
