Pollutants released by Steel Industry in India

The steel industry is one of the major contributors to air pollution in India. The pollutants released by the steel industry can have serious health and environmental impacts. Some of the important pollutants released by the steel industry in India are:

1. Oxides of sulphur: The burning of coal and coke in the steel industry releases oxides of sulphur into the air. These pollutants can cause respiratory problems and acid rain.

2. Oxides of nitrogen: The high-temperature processes used in the steel industry can also release oxides of nitrogen into the air. These pollutants can contribute to smog and respiratory problems.

3. Carbon monoxide: The incomplete burning of coal and coke in the steel industry can release carbon monoxide into the air. This pollutant is toxic and can cause headaches, dizziness, and even death.

4. Carbon dioxide: The steel industry is a major contributor to greenhouse gas emissions, releasing large amounts of carbon dioxide into the atmosphere. This pollutant contributes to climate change and global warming.

Correct Answer: D) 1, 2, 3, and 4

All of the above pollutants are released by the steel industry in India, making it a major contributor to air pollution and climate change. It is important for the steel industry to adopt cleaner production processes and reduce its emissions to protect public health and the environment.
