  2. DEFINITION: WHAT IS LAND POLLUTION? • The result of man’s misuse of the soil • The degradation of the health and quality of the land surface • The addition of undesirable matter to the land, matter that damages terrestrial organisms that depend on the land.

  3. CAUSES OF LAND POLLUTION 1. Agriculture 2. Mining and Quarrying • Accumulation of animal manures • Excessive input of chemical fertilizers • Illicit dumping of tainted crops on land • Overgrazing • Use of explosives to blow up mines • Use of machineries which emit toxic byproducts that leak to the ground

  4. CAUSES OF LAND POLLUTION 3. Sewage Sludge • Improper or inadequate sanitation system causes sludge to leak at surrounding soil

  5. HEALTH EFFECTS • Diseases transmit from direct contact with polluted soil or from contact with other resources, such as water that has made direct contact with polluted soil. • Children are more susceptible simple because they usually have more frequent contact with the soil as compared to adults. • Diseases causes by land pollution include: cancer, neurological problems, and tissue damage and irritation. • Indirectly affects the respiratory system. The polluted dust and/or particles can enter the lungs. • Skin problems are frequently linked to land pollution. • One of the leading causes for birth defects. Pregnant women living in unhealthy and dirty environment can incur breathing problems and a number of diseases, which may affect the health of the baby as well.

  6. HEALTH EFFECTS: CHEMICAL POISONING • Organ damage and bioaccumulation

  7. HEALTH EFFECTS: CHEMICAL POISONING

  8. ENVIRONMENTAL EFFECTS Animals Soil • Toxic litter can be eaten by wildlife, both in the water and on land • Pests increase as the edible garbage become breeding grounds resulting in an increase of their population and communicable diseases. These diseases can be transferred to other animals. • Pesticides have unintended effects on plants and animals inadvertently exposed during application. A common agricultural pesticide, atrazine has different effects with respect to which animal receives exposure. For example, reptile eggs were not found to be affected, likely due to their thick, leathery shell. Conversely, quail were found to have reduced food consumption and inhibited reproductive capabilities. • Items such as batteries, light bulbs and televisions leach toxic chemicals like mercury into the ground. • Sources like smokestacks and fertilizers can coat large plots of land with toxins. These chemicals enter the soil, either attached to soil particles or trapped in air pockets. They then contaminate local plant and animal life, as well as nearby water systems.

  9. ENVIRONMENTAL EFFECTS Water Plants • Chemicals that enter the soil can easily spread to water systems. • Groundwater absorbs chemicals from the soil. It is often used to supply local communities with drinking water, and to support local agriculture. Nearby rivers can sweep chemicals downstream toward oceans or lakes, which affects fish and other wildlife. • As pollution is introduced into major bodies of water it begins to saturate the water with phosphates and nitrates, especially when human waste is introduced. This over-saturation causes an exponential growth in algae and other plants, which can ultimately block the sun's rays from reaching deep into the water. • Toxic chemicals can seep into the ground and contaminate local affect every part of the ecosystem---both plants and animals. If plants are exposed to harmful pollution, their fruits may become tainted, thus placing animals who feed on these plants in danger of being poisoned.

  10. WAYS TO PREVENT/MINIMIZE THE PROBLEM • Reduce, reuse, recycle • Buy biodegradable products • Avoid the use of pesticides • Don’t litter • Use reusable containers • Try to use organic products (products that are biodegradable and environment-friendly) • Have a proper waste management system • Make use of scratch paper • Avoid the use of plastic shopping bags – use reusable bags instead
