Effects on plants of Air pollutants

SO₂, O₃ and NO₂ are strong oxidants and can bring about significant changes in plant cell chemistry. The general effects of pollutants are as follows:

• Damage to leaves,
• Inhibition of photosynthesis,
• Reduced nutrient uptake,
• Leaching of plant nutrients in soil,
• Release of poisonous metal ions that are normally bound to the soil and
• Killing of essential microorganisms in the soil.
