What is Geogenic source?
Geogenic sources like leaching and weathering of rocks and anthropogenic activities such as intensive metal mining, smelting, combustion of fossil fuels, use of pesticides, and sewage sludge have burdened the soil with number of heavy metals (Kumar et al., 2015a).
What is Geogenic pollution?
“Geogenic pollution” of groundwater refers to naturally occurring elevated concentration of certain elements in groundwater having negative health effects.
What soil pollutants is a Geogenic source?
Contaminants such as trace elements, radionuclides, asbestos and other contaminants occur naturally in soils due to geological and pedological processes without anthropogenic influence (ISO, 2015; Tian et al., 2017).
What is Geogenic?
geogenic (comparative more geogenic, superlative most geogenic) Of or relating to the history of the earth. Resulting from geological processes.
What are the effects of soil pollution?
Soil pollution causes a chain reaction. It alters soils’ biodiversity, reduces soil organic matter and soils’ capacity to act as a filter. It also contaminates the water stored in the soil and groundwater, and causes an imbalance of soil nutrients.
What are the natural sources of water pollution?
Among them, the most important ones are the fluorine salts (fluorides), which is the way this element is found in nature, and arsenic, a very common metalloid found in the atmosphere, the hydrosphere and the soil; there are other natural pollutants such as manganese, uranium, radon, cesium and lithium.
What are 5 ways groundwater can be polluted?
There are five major ways groundwater can be contaminated by chemicals, bacteria or saltwater.
- Surface Contamination.
- Subsurface Contamination.
- Landfills and Waste Disposal.
- Atmospheric Contamination.
- Saltwater Contamination.
How does well water become polluted?
Water run-off from rainfall or snow-melt can contaminate private wells by washing microorganisms into the well system or seeping underground. Leakage of waste from underground storage tanks and effluent from septic leach fields can reach a water source and result in microorganisms being present in water wells.
What are the 5 effects of soil pollution?
The most important effects of soil pollution according to IPBES and the FAO are indicated below:
- Damage to health.
- Poorer harvests.
- Climate change.
- Water and air pollution.
- Population displacement.
- Species extinction.
- Desertification.
- Economic impact.
What are the major soil pollutants?
Some soil pollutants include heavy metals, hydrocarbons, inorganic and organic solvents. Dumping of refuse on open land, waste burning, and inadequate landfills are the major contributors to soil pollution.
Is radon a natural source of soil pollution?
Radon is a natural product of the environment and the principal natural-background, radiation exposure source in the United States (Krewski et al. 2005). Radon gas moves freely through the air, groundwater, and surface water. The main source of indoor radon gas infiltration is from soil into buildings.
Is groundwater contaminated?
Unfortunately, groundwater is susceptible to pollutants. Groundwater contamination occurs when man-made products such as gasoline, oil, road salts and chemicals get into the groundwater and cause it to become unsafe and unfit for human use.
What are the 5 causes of soil pollution?
Among the most common causes of soil contamination caused by human activity, the FAO highlights industry, mining, military activities, waste — which includes technological waste — and wastewater management, farming, stock breeding the building of urban and transport infrastructures.
What is soil pollution causes and effects?
The soil contamination can occur due to the presence of chemicals such as pesticides, herbicides, ammonia, petroleum hydrocarbons, lead, nitrate, mercury, naphthalene, etc in an excess amount. The primary cause of soil pollution is a lack of awareness in general people.
What are the 10 causes of water pollution?
What causes water pollution?
- 1- Sewage or wastewater: The waste from households, factories, or agricultural land gets discharged into rivers or lakes.
- 2- Dumping:
- 3- Oil pollution:
- 4- Acid rain:
- 5- Industrial waste:
- 1- Diseases:
- 2- Ruination of the ecosystem:
- 3- Eutrophication:
What are the 5 causes of water pollution?
MAIN CAUSES OF WATER POLLUTION
- Global warming.
- Deforestation.
- Industry, agriculture and livestock farming.
- Rubbish and faecal water dumping.
- Maritime traffic.
- Fuel spillages.
What are the 10 effects of water pollution?
EFFECTS OF WATER POLLUTION
- Destruction of biodiversity. Water pollution depletes aquatic ecosystems and triggers unbridled proliferation of phytoplankton in lakes — eutrophication —.
- Contamination of the food chain.
- Lack of potable water.
- Disease.
- Infant mortality.
What are the main causes of groundwater pollution?
Major Causes of Groundwater Pollution
- Naturally Occurring(Geogenic) Chemicals.
- Poor Sanitation Systems.
- Improper Sewage Dispossal.
- Excessive Use of Fertilizers and Pesticides.
- Leakage from Industrial Pipes and other industrial releases.
- Over pumping of groundwater.
- Improper Landfill practices.
- Using the Precautionary Principle.
What are 10 diseases caused by polluted water?
Contaminated water and poor sanitation are linked to transmission of diseases such as cholera, diarrhoea, dysentery, hepatitis A, typhoid and polio. Absent, inadequate, or inappropriately managed water and sanitation services expose individuals to preventable health risks.
Why is groundwater pollution a problem?
Contamination of ground water can result in poor drinking water quality, loss of water supply, degraded surface water systems, high cleanup costs, high costs for alternative water supplies, and/or potential health problems. The consequences of contaminated ground water or degraded surface water are often serious.
What are the main causes of soil and air pollution?
However, the leading causes are listed below.
- Industrial Activity. Industrial activity has been the biggest contributor to the problem in the last century, especially since the amount of mining and manufacturing has increased.
- Agricultural Activities.
- Waste Disposal.
- Accidental Oil Spills.
- Acid Rain.
What is radon caused by?
Radon is a radioactive gas that forms naturally when uranium, thorium, or radium, which are radioactive metals break down in rocks, soil and groundwater. People can be exposed to radon primarily from breathing radon in air that comes through cracks and gaps in buildings and homes.
What are the harmful effects of radon?
Radon gas decays into solid radioactive particles that can get trapped in your lungs when you inhale them. As they break down further , these particles release small bursts of energy. This can damage lung tissue and lead to lung cancer over the course of your lifetime.
What are the 7 types of water pollution?
Types of Water Pollution
- Groundwater.
- Surface water.
- Ocean water.
- Point source.
- Nonpoint source.
- Transboundary.
- Agricultural.
- Sewage and wastewater.
What are 10 causes of soil pollution?
Soil pollution is mostly caused by mindless human activities such as:
- Industrial waste.
- Deforestation.
- Excessive use of fertilisers and pesticides.
- Garbage pollution.
- Climate change.
- Loss of soil fertility.
- Impact on human health.
- Reforestation.
