Water Pollution Sources and ImpactsOne of the most useful describes pollution in terms of its source and effects. Using this framework, the three main categories of water pollution are point-source, nonpoint-source and trans-boundary.
The inorganic pollutants and their organic forms have a devastating negative health effects on the flora and fauna of the earth system (atmosphere, hydrosphere, and geosphere) causing several, human health problems (abnormal growth, high risk of cancer, diabetes, obesity, etc.).
In general, there are four groups of inorganic compound types. They are divided into bases, acids, salts, and water.
Inorganics include salts, metals, substances made from single elements and any other compounds that don't contain carbon bonded to hydrogen. Some inorganic molecules do, in fact, contain carbon. table salt or sodium chloride, NaCl. carbon dioxide, CO2. diamond (pure carbon)
Organic pollutants includes phenols, chlorinated phenols, endocrine disrupting chemicals, azo dyes, polyaromatic hydrocarbons, polychlorinated biphenyls, pesticides, etc., whereas inorganic pollutants includes a variety of toxic heavy metals such as cadmium (Cd), chromium (Cr), arsenic (As), lead (Pb), mercury (Hg),
What are Inorganic Gaseous Pollutants? Pollutants like carbon dioxide (CO2), carbon monoxide (CO), sulphur dioxide (SO2), nitrous oxide (NO) and nitrogen dioxide (NO2) are collectively called as Inorganic gaseous pollutants. These are the major contributors to the indoor air pollution.
All living organisms contain carbon-based compounds, making them organic. Our bodies are composed mostly of water, H2O, and it is necessary for us to survive. However, water is an example of an inorganic compound because it does not contain carbon and it was not formed by a living organism.
Inorganic substances are a group of chemicals that contain no carbon. Examples include ammonia, hydrogen sulfide, all metals, and most elements (such as calcium).
Another distinction is that carbon substances containing only a few elements, and have their names derived from those elements, are inorganic compounds (carbon dioxide, hydrogen cyanide, sodium chloride). Water is definitely an inorganic compound (dihydrogen oxide) and methyl alcohol is definitely an organic compound.
The most common drinking water contaminants are microorganisms, nitrate, and arsenic. Water quality monitoring has improved over the past five years. Bacteria, viruses, and protozoa (such as Giardia lamblia and Cryptosporidium) are drinking water contaminants that can rapidly cause widespread and serious illnesses.
And, unlike inorganic lead compounds, organic lead can be readily absorbed through the skin. Most lead encountered in the environment today is inorganic.
Inorganic substances sometimes affect human health or ecological systems when eluted from the earth's crust into water. In many cases, materials such as arsenic, fluoride and boron are contained in groundwater; however, sometimes they flow to the surface of the earth as spring water.
Inorganic contaminants such as lead, arsenic, antimony, and radium may exist in public water supplies in trace amounts at the entry points to the water distribution system.
The most common and widespread contaminants in Florida are bacteria, nitrates and lead. Other chemicals like ethylene dibromide (EDB), tetrachlorethylene (PCE) and temik have also been found in isolated areas. Contaminated drinking water can cause a number of diseases, and is sometimes fatal to vulnerable people.
Environmental pollutants are of two types: organic and inorganic. Organic pollutants mainly include phenols, nonylphenols, chlorinated phenols, azo dyes, phthalic esters, petroleum hydrocarbons, pesticides, persistent organic pollutants (POPs), etc.
Water pollution occurs when harmful substances—often chemicals or microorganisms—contaminate a stream, river, lake, ocean, aquifer, or other body of water, degrading water quality and rendering it toxic to humans or the environment.
There are four main categories of water pollution: pathogens, inorganic compounds, organic material and macroscopic pollutants.
The most common types of water pollution include:
- Agriculture. Agriculture plays a major role in water pollution around the world.
- Wastewater and Sewage. Wastewater is any type of water that is used for industrial, agricultural, or commercial activities.
- Oil Pollution.
- Radioactive Waste.
- Urban Development.
- Plastics.
The 12 targeted POPs include eight pesticides (aldrin, chlordane, DDT, dieldrin, endrin, heptachlor, mirex, and toxaphene), two types of industrial chemicals (polychlorinated biphenyls or PCBs and hexachlorobenzene), and two chemical families of unintended by-products of the manufacture, use, and/or combustion of
Substances
- Fossil Fuels.
- Organic Chemicals.
- Particulate Matter.
- Polycyclic Aromatic Hydrocarbons.
- Vehicle Emissions.
Some common waterborne contaminants include:
- Lead.
- Nitrates/Nitrites.
- Mercury.
- Perchlorate.
- Radium.
- Selenium.
- Silver.
- Uranium.
Agricultural PollutionAgricultural processes such as uncontrolled spreading of slurries and manure, disposal of sheep dip, tillage, ploughing of the land, use of pesticides and fertilisers can cause water pollution. Accidental spills from milk dairies can also affect the quality of water.
A pollutant is a substance or energy introduced into the environment that has undesired effects, or adversely affects the usefulness of a resource. Some pollutants are biodegradable and therefore will not persist in the environment in the long term.
But there's actually serious harm associated with its disposal in landfills. Due to the lack of oxygen, organic waste undergoes the process of anaerobic decomposition when it's buried in a landfill. This generates methane, which is then released into our atmosphere.
Organic pollutants originate from domestic sewage (raw or treated), urban run-off, industrial (trade) effluents and farm wastes. Sewage effluents is the greatest source of organic materials discharged to freshwaters.
Organic Substance -- Organic pollution occurs when an excess of organic matter, such as manure or sewage, enters the water. When organic matter increases in a pond, the number of decomposers will increase. These decomposers grow rapidly and use a great deal of oxygen during their growth.
Mining, metal smelting and burning of fossil fuels are the major industrial processes that contribute to arsenic contamination of air, water and soil. The use of arsenic-containing pesticides in the past has left large areas of agricultural land contaminated.
Answer: Explanation: River, ocean & soil.
Organic describes things that are natural or related to nature. In common usage, organic is used to mean “healthful” or “close to nature.” It can also describe foods grown without artificial pesticides or fertilizers. In other uses, organic refers to living things or material that comes from living things.
Coliform bacteria, which are not an actual cause of disease, are commonly used as a bacterial indicator of water pollution.
Illegal dumping of the solid wastes, polluted water absorbed by the soil, use of chemical fertilizers and pesticides, dumping of minerals, oils, and radioactive wastes are the major causes of soil pollution (Cachada et al. 2018).
Diseases: In humans, drinking or consuming polluted water in any way has many disastrous effects on our health. It causes typhoid, cholera, hepatitis and various other diseases. Destruction of Ecosystems: Ecosystems are extremely dynamic and respond to even small changes in the environment.
