The contamination of air by pollutants such as dust, smoke, and harmful gases is known as air pollution. Effects of Air Pollution on Animals and Plants are
Effects of Air Pollution on Animals and Plants
- Nitrogen dioxide leads to the premature falling of leaves. It also affects the growth of plants resulting in low crop yields.
- Ozone enters the leaves of plants through stomata. It then dissolves with water within the plant and reacts with other chemicals damaging the leaves. Plants weakened by ozone may become more susceptible to various diseases, pests, and droughts.
- Nitrogen dioxide causes premature falling of leaves. It also suppresses the growth of plants. This reduces crop yields.
- Peroxyacetyl Nitrate damages leafy vegetables and causes premature fall and discoloration of leafy vegetables.
- Sulphur dioxide has a bleaching effect on plants. It results in the loss of chlorophyll. Many leafy vegetables become yellow because of the effect of the gas.
- Air pollution infects the leaves of plants. When these leaves are consumed by animals, they are affected by arsenic and lead poisoning. As a result of lead poisoning, animals may suffer from bronchitis and the loss of appetite.
Apart from these, air pollution may damage the painted surfaces, fabrics, and buildings. Example: Acid rain damages buildings made of marble and limestone. The Taj Mahal has faced damage because of acid rain. Sulphuric dioxide when mixed with moisture causes corrosion of metals such as steel, copper, and zinc.
