The steel industry in India releases various pollutants into the environment, including:

1. Oxides of sulphur (SOx): These are emitted during the combustion of fossil fuels and are a result of the presence of sulphur in the fuel. They contribute to air pollution and can cause respiratory issues and acid rain.

2. Oxides of nitrogen (NOx): These are produced from the high-temperature combustion processes in the steel industry. They contribute to air pollution and can lead to the formation of smog and respiratory problems.

3. Carbon monoxide (CO): This is produced during the incomplete combustion of carbon-based fuels. It is a toxic gas that can be harmful to human health, especially in enclosed spaces.

4. Carbon dioxide (CO2): This is a greenhouse gas that is released during the combustion of fossil fuels. It is a major contributor to climate change and global warming.

These pollutants have significant environmental and health impacts, and efforts are made to control and reduce their emissions from the steel industry through various pollution control measures.
