1. Inhibition of photosynthesis: Heavy metals such as lead, cadmium, and mercury can inhibit the process of photosynthesis in plants, leading to reduced growth and productivity.
2. Damage to cell membranes: Heavy metals can cause damage to the cell membranes of plants, affecting their ability to take up water and nutrients from the soil.
3. Interference with nutrient uptake: Heavy metals can interfere with the uptake of essential nutrients such as phosphorus, potassium, and magnesium in plants, leading to nutrient deficiencies and stunted growth.
4. Disruption of enzyme activity: Heavy metals can disrupt the activity of enzymes in plants, which are essential for various metabolic processes. This can lead to impaired growth and development.
5. Production of reactive oxygen species: Heavy metals can induce the production of reactive oxygen species in plants, leading to oxidative stress and damage to cellular components.
6. Accumulation in plant tissues: Heavy metals can accumulate in plant tissues, especially in the roots and leaves, leading to toxicity and ultimately death of the plant.
7. Impact on soil microbial activity: Heavy metals can also affect the diversity and activity of soil microorganisms, which play a crucial role in nutrient cycling and plant health.
