**Components of Air Harmful to Living Beings: Smoke and Water Vapour**
Air is a mixture of gases that is essential for the survival of all living beings. However, there are certain components present in the air that can be harmful to living beings, especially when they are present in high concentrations. The two components of air that are particularly harmful to living beings are smoke and water vapor.
**1. Smoke:**
Smoke is a mixture of solid and liquid particles that are produced as a result of the incomplete combustion of organic materials. It is commonly released from sources such as burning forests, industrial processes, and vehicle emissions. The harmful effects of smoke on living beings are as follows:
- Smoke particles can irritate the respiratory system, causing coughing, wheezing, and difficulty in breathing.
- Prolonged exposure to smoke can lead to respiratory diseases such as bronchitis and asthma.
- The presence of harmful chemicals in smoke, such as carbon monoxide and nitrogen oxides, can have toxic effects on the body.
**2. Water Vapor:**
Water vapor is the gaseous form of water that is present in the atmosphere. While water vapor itself is not harmful to living beings, excessive humidity caused by high levels of water vapor can have negative effects. The harmful effects of water vapor on living beings are as follows:
- High humidity levels can make it difficult for the body to regulate its temperature, leading to discomfort, fatigue, and heat-related illnesses.
- Excessive moisture in the air can create a conducive environment for the growth of mold and bacteria, which can cause respiratory problems and allergies.
**Conclusion:**
In conclusion, the components of air that are harmful to living beings are smoke and water vapor. Smoke contains harmful particles and chemicals that can irritate the respiratory system and cause respiratory diseases. Excessive humidity caused by high levels of water vapor can lead to discomfort, heat-related illnesses, and the growth of mold and bacteria. Therefore, it is important to minimize exposure to these harmful components of air to maintain good health.
