Land pollution can be defined as acts occurring on an area resulting in colour change, fertility, and erosion. It is caused by waste in the form of liquid or solid.
Introduction to Land Pollution
The presence of chemicals or other alteration in the natural soil environment Results in a change of the soil quality Affects the normal use of the soil
Endangering public health and the living environment
Causes of LAND POLLUTION
1. By poor agricultural practices
Excessive use of fertilizers & pesticides. Farmers use fertilizers and pesticides in order to kill pests and have an abundant harvest, but some people use excessive amounts of fertilizers and pesticide, which causes pollution
Excessive farming, construction, overgrazing, burning of grass cover and deforestation
2. By mineral exploitation
This includes piles of coal refuse and heaps of slag and underground debris. Mining and forestry activities that clear the land surfaces (clear cutting) and use 'skid trails' often leave the land not restored. The surface is exposed to erosion which destroys the quality of the land. Additionally, iron and other chemicals such as copper, mercury and lead from mining practices leach into the soil, polluting it and leaving it exposed to water bodies as well.
3. By indiscriminate disposal of urban wastes.
The waste materials that cause land pollution are broadly classified as municipal solid waste (MSW, also called municipal refuse), construction and demolition (C&D) waste or debris, and hazardous waste. MSW includes non hazardous garbage, rubbish, and trash from homes, institutions, commercial establishments, and industrial facilities. C&D waste includes wood and metal objects, wallboard, concrete rubble, asphalt, and other inert materials produced when structures are built, renovated or demolished.
