Land pollution, also known as soil pollution, is actually the process wherein soil is contaminated due to the introduction of some harmful chemical substances in it. Among the various human activities which contribute to land pollution, agriculture and mining are perhaps the most prominent ones. When it comes to soil pollution, the list of contaminants includes Chlorinated Hydrocarbons (CFH), chromium, cadmium, lead, zinc, etc. Other than the practice of agriculture and mining, dumping of industrial and domestic waste in the soil also pollutes it.
