The correct answer is Both 1 and 2.
- Soil Pollution:
- It is the result of dumping garbage, waste & toxins making the land making the land contaminated or polluted.
Key-Points - Causes of Soil Pollution:
- Some of the causes are the following:
- Indiscriminate use of fertilizers, pesticides, insecticides.
- Loss of the natural nutrients of the soil.
- Imbalance in the flora & fauna of the soil.
- Hence, statement 1 is correct.
- Pollution due to Urbanisation.
- Dumping of large quantities of solid waste.
- Deforestation and soil erosion.
Sources of Soil Pollution: - Acid rain.
- Pesticides.
- Radioactive wastes.
- Industrial wastes.
- Fertilizers, manures.
- Materials like asphalt, leather, cans, plastics, glass, paper & dead bodies.
Measures to control Soil Pollution: - Recycling of plastics wastes.
- Ban of Deforestation.
- Encouraging social forestry.
- Ban on the usage of plastics below 20 microns.
- Encouraging the plantation programme.
Techniques to treat polluted Soil: - Phytoremediation:
- It is the use of plants to remove pollutants from water & soil.
- Natural phytoremediation is done mainly with the help of wetland vegetations like mangroves, Estuarine plants etc.
- Hence, statement 2 is correct.
Mycoremediation: - It involves the use of fungal mycelia to filter toxic waste & microorganisms.
Rhizofiltration: - It is the water remediation technique that involves the uptake of pollutants by plant roots.

Soil pollution refers to the contamination of soil by the presence of harmful substances, which can have a detrimental impact on both the soil and the organisms living in it. Let's examine the given statements in detail:
1. Imbalance in the flora and fauna of the soil leads to soil pollution:
The statement is correct. Flora and fauna play a crucial role in maintaining the health and fertility of the soil. When there is an imbalance in the composition and diversity of these organisms, it can lead to soil pollution. For example, excessive use of chemical fertilizers and pesticides can kill beneficial microorganisms in the soil, disrupting the natural balance and causing pollution. Similarly, the absence of certain plant species can result in nutrient deficiencies, affecting soil quality.
2. Phytoremediation is effective in treating soil pollution:
The statement is correct. Phytoremediation is a technique that uses plants to remove, degrade, or immobilize contaminants from the soil. Plants have the ability to absorb and accumulate pollutants through their roots, stems, and leaves. They can break down or convert these pollutants into less harmful forms, effectively treating soil pollution. Different types of plants have different capacities for cleaning up specific contaminants. For example, some plants are efficient in removing heavy metals, while others are effective in degrading organic pollutants. Phytoremediation is an eco-friendly and cost-effective approach to remediate polluted soil.
In conclusion, both statements are correct. Imbalance in the flora and fauna of the soil can indeed lead to soil pollution, and phytoremediation is an effective technique for treating soil pollution. It is important to address soil pollution as it directly affects agricultural productivity, ecosystem health, and human well-being. Implementing sustainable agricultural practices, reducing the use of chemical inputs, and promoting phytoremediation techniques can greatly contribute to preventing and remedying soil pollution.
