Soil contamination, soil pollution, or land pollution as a part of land degradation is caused by the presence of xenobiotic (human-made) chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste .
The causes of soil alkalinity can be natural or man-made: The natural cause is the presence of soil minerals producing sodium carbonate (Na 2 CO 3) and sodium bicarbonate (NaHCO 3) upon weathering. Coal-fired boilers / power plants, when using coal or lignite rich in limestone, produce ash containing calcium oxide.
Buildup of cadmium levels in the water, air, and soil has been occurring particularly in industrial areas. Environmental exposure to cadmium has been particularly problematic in Japan where many people have consumed rice that was grown in cadmium-contaminated irrigation water. This phenomenon is known as itai-itai disease. [8]
The students tested the bacteria in the soil as part of the Tiny Earth program. 2 NWTC students found a new antibiotic in soil at Pamperin Park. Here's why it's so groundbreaking.
Soil pollution in Southern Africa; Soil vapor extraction; Solvent; Spodden Valley asbestos controversy; Surface runoff; Surfactant leaching (decontamination)
Land consumption as part of human resource consumption is the conversion of land with healthy soil and intact habitats into areas for industrial agriculture, traffic (road building) and especially urban human settlements. More formally, the EEA [1] has identified three land consuming activities: The expansion of built-up area which can be ...
Plutonium is known to bind to soil particles very strongly (see above for an X-ray spectroscopic study of plutonium in soil and concrete). While caesium has very different chemistry to the actinides, it is well known that both caesium and many of the actinides bind strongly to the minerals in soil.
The soil and rock removed is deposited in nearby valleys, hollows and depressions, resulting in blocked (and contaminated) waterways. [10] [11] Removal of soil and rock overburden covering the coal resource may cause burial and loss of topsoil, exposes parent material, and creates large infertile wastelands.
