Soil pollution is characterized by the presence of harmful synthetic compounds in soil that pose hazards to human and environmental health. Land pollution is the destruction and pollution of land through direct and indirect human activities like deforestation, agricultural chemicals, industrialization, mining, landfills and fuel spillages. Major sources of soil pollution include domestic and industrial wastes, e-waste, and nuclear waste. Soil pollutants include detergents, heavy metals, pesticides, organic dyes, and pathogenic microorganisms. Effects of soil pollution are soils unfit for agriculture, spread of diseases, bioaccumulation of toxins, eutrophication, and contamination of groundwater. Control measures include treatment of effluents

2. Definition of Land and Soil Pollution
Soil pollution is characterized by the
presence of harmful synthetic compounds
(poisons or contaminants) in soil, in high
amounts as a hazard to human wellbeing as
well as the biological system.
Land pollution is the destruction and
pollution of the land through the direct and
indirect activities of human beings.

5. Deforestation and soil disintegration
Agricultural Synthetics such as pesticides
and herbicides
Industrialization and Mining
Landfills
Human sewage
Fuel spillage from cars/trucks that escape
because of rain and saturate adjacent soil.
Causes of land and soil pollution

6. SOURCES OF SOIL POLLUTION
Domestic wastes: Garbage, Waste materials like
glass, paper, plastics, cans, carry bags, Waste cloth and
Bathing water.
Industrial Waste: Effluents from chemical, paper,
cement, textile, pharmaceutical, Fertilizer, Pesticide
industries, Metal Refineries, Distilleries, Mines and
Sewage waste.
E-waste: Dumped Electronic goods, Lithium ion
batteries, IC’s, PCB’s & Bulbs.
Nuclear Waste: Spent Nuclear materials and
Radioactive components.

7. SOIL POLLUTANTS
DETERGENTS
HEAVY METALS
PESTICIDES
ORGANIC DYES
PARTICULATE MATTER
ACIDS & ALKALIES
RADIO ACTIVE METALS – Strontium -90,
Iodine -131, Cesium-137
PATHOGENIC MICRO ORGANISMS.

8. •Soil is unfit for agriculture – Highly acidic or alkaline
•Spread of diseases due to pathogenic microorganisms.
•Bio-magnification of Heavy Metals &Pesticides –Enter
into Human system.
•Eutrophication of water bodies.
•Radio active isotopes in human system- Strontium 90
causes cancer.
•Contamination of ground water.
•Biodiversity effects- Soil ecosystem is degraded.
EFFECTS OF SOIL POLLUTION

9. A. Treatment of effluents before discharging.
B. Segregation of Solid waste and disposal
 Biodegradable waste – Composting & Vermicomposting.
 Non Biodegradable waste- Land fills.
C. Biogas generation – Sludge becomes Manure.
D. Reduce, Recycle and Reuse
E. Ban toxic chemicals and pesticides that get Biomagnified.
F. Use of Fertilizers should be judicious. Promotion of Organic
farming.
G. Controlled grazing and forest management.
H. Planting of soil binding grass in slopes prone to rapid erosion.
