Inorganic pollutants are contaminants that do not contain carbon and can enter the water supply from natural causes or contamination. Human activities such as industrial processes, mining, smelting, and chemical manufacturing, as well as agricultural practices and improper waste disposal, are the primary sources of inorganic pollutants in water. These pollutants can have severe health risks and environmental impacts, including neurological disorders, cancer, cognitive function and development issues, and algal blooms.

What You'll Learn
Heavy metals like lead, mercury, and arsenic are persistent and bioaccumulative
These metals are persistent because they do not break down easily and can accumulate in the environment over time. They are bioaccumulative because they can be absorbed by organisms and build up in their tissues over time. This means that even small amounts of these metals in the environment can have severe health impacts on both humans and wildlife.
The primary sources of inorganic pollutants in water are human activities. Industrial processes like mining, smelting, and chemical manufacturing release heavy metals and other inorganic pollutants into water bodies. Agricultural practices contribute nitrates and phosphates from fertilisers and pesticides. Residential areas, through improper waste disposal and sewage, also contribute to this issue.
Exposure to inorganic pollutants through consumption or contact with contaminated water has grave implications for human health. Many of these pollutants, such as lead and mercury, are neurotoxins, impacting cognitive function and development, especially in children. Others, like arsenic, are carcinogenic.
Inorganic pollutants can also have adverse effects on the environment. Nitrates and phosphates, primarily stemming from agricultural runoff, cause eutrophication, leading to algal blooms and 'dead zones' in water bodies. Heavy metals can also accumulate in aquatic organisms, leading to bioaccumulation and biomagnification in the food chain.

Nitrates and phosphates cause eutrophication and algal blooms
Nitrates and phosphates are inorganic pollutants that are primarily stemming from agricultural runoff and cause eutrophication, leading to algal blooms and 'dead zones' in water bodies.
These nutrients are released into water bodies through agricultural practices and residential areas, through improper waste disposal and sewage. Industrial processes like mining, smelting, and chemical manufacturing also release heavy metals and other inorganic pollutants into water bodies.
Exposure to inorganic pollutants through consumption or contact with contaminated water has grave implications for human health. Many of these pollutants, such as lead and mercury, are neurotoxins, impacting cognitive function and development, especially in children. Others, like arsenic, are carcinogenic.
Inorganics can include a combination of metals, salts, compounds, particles, and mineral complexes which do not contain carbon; carbon compounds are organics. Water is not pure H₂0; some of the most common contaminants or conditions include carbon dioxide and other gases, salts like Chloride, Sodium, Carbonate, Alkalinity, Calcium, Potassium, Iron, and Manganese.
Inorganic contaminants include natural or man-made elements or compounds that can contaminate water or be concentrated in the water cycle. Water is not pure H₂0; some of the most common contaminants or conditions include carbon dioxide and other gases, salts like Chloride, Sodium, Carbonate, Alkalinity, Calcium, Potassium, Iron, and Manganese.

Carbon dioxide and other gases are common contaminants
Water is not pure H20; some of the most common contaminants or conditions include carbon dioxide and other gases, salts like Chloride, Sodium, Carbonate, Alkalinity, Calcium, Potassium, Iron, and Manganese. For the most part, the inorganic contaminants create aesthetic problems such as: a salty or bitter taste, discoloration, or even chemical scale/corrosion.
Other gases that can contaminate water include ammonia (NH3) and hypochlorite. Ammonia is a common chemical used in cleaning products and can be released into the environment through agricultural and industrial activities. When ammonia dissolves in water, it can form ammonium ions, which can be toxic to aquatic life at high concentrations. Hypochlorite is a chemical compound commonly used in water treatment processes to disinfect water and kill harmful bacteria. However, if not properly controlled, hypochlorite can remain in the water and cause irritation to the skin and eyes and may have other negative health effects.
Inorganic pollutants in water are primarily sourced from human activities. Industrial processes like mining, smelting, and chemical manufacturing release heavy metals and other inorganic pollutants into water bodies. Agricultural practices contribute nitrates and phosphates from fertilisers and pesticides. Residential areas, through improper waste disposal and sewage, also contribute to this issue. Exposure to inorganic pollutants through consumption or contact with contaminated water has grave implications for human health. Many of these pollutants, such as lead and mercury, are neurotoxins, impacting cognitive function and development, especially in children. Others, like arsenic, are carcinogenic.

Chloride, sodium, and alkalinity are salts found in water
Chloride is a salt that is commonly found in water. It is a major component of table salt and is often used in the food industry. Chloride ions can be found in seawater and brackish water and can also be introduced into water supplies through industrial activities such as mining and chemical manufacturing.
Sodium is another salt that is commonly found in water. It is an essential element for plant and animal life and is often used in the food industry. Sodium ions can be found in seawater and brackish water and can also be introduced into water supplies through industrial activities such as mining and chemical manufacturing.
Alkalinity is a measure of the water's ability to resist changes in pH. It is an important parameter in water quality and is often used in the food industry. Alkalinity can be found in seawater and brackish water and can also be introduced into water supplies through industrial activities such as mining and chemical manufacturing.
These salts can have adverse effects on human health and the environment. Exposure to inorganic pollutants through consumption or contact with contaminated water has grave implications for human health. Many of these pollutants, such as lead and mercury, are neurotoxins, impacting cognitive function and development, especially in children. Others, like arsenic, are carcinogenic.
