Carbon Monoxide:
Carbon monoxide is a colorless, odorless gas that is produced by the incomplete combustion of carbon-containing fuels such as gasoline, wood, and coal. It is highly toxic and can be deadly if inhaled in large amounts. Carbon monoxide binds to hemoglobin in red blood cells, reducing the blood's ability to carry oxygen to the body's tissues and organs. Symptoms of carbon monoxide poisoning include headaches, dizziness, nausea, and confusion. It is important to have carbon monoxide detectors in homes to prevent accidental poisoning.

Carbon Dioxide:
Carbon dioxide is a naturally occurring gas that is essential for plant life through the process of photosynthesis. However, human activities such as burning fossil fuels and deforestation have led to an increase in carbon dioxide levels in the atmosphere, contributing to global warming and climate change. Excessive levels of carbon dioxide can also cause health problems in humans, such as difficulty breathing and headaches. It is important to reduce carbon dioxide emissions by using renewable energy sources and promoting sustainable practices.

Oxides of Sulphur and Nitrogen:
Oxides of sulphur and nitrogen are air pollutants that are released into the atmosphere during the combustion of fossil fuels, industrial processes, and transportation. These pollutants can react with other chemicals in the atmosphere to form acid rain, which can damage forests, crops, and aquatic ecosystems. Oxides of sulphur and nitrogen can also contribute to respiratory problems in humans, especially in vulnerable populations such as children and the elderly. It is important to reduce emissions of these pollutants through the use of cleaner technologies and stricter regulations on industrial emissions.
