Write down six examples of impurities in water
Answers
Answer:
Each pollutant carries its own risk in chemical and biological research, not to mention the old damage to pure water quality. Here we discuss eight types of water pollution, and how they can be prevented.
1. Microorganisms
Germs, algae and fungi all hamper the functioning of sterile research. Viruses can have a negative impact on cell and tissue culture by competing in enzymes in the lower extremities.
2. Viruses
Germs - called nucleic acids - negatively affect the tissue and cell growth. They are very small, and most of them fall within the range of 0.01 - 0,3 microbuses, and can live much longer. Once seen in water, they should be removed as soon as possible.
3. Pyrogens
For the mammalian cell culture, as well as the preparation of solutions or devices that will be able to interact with humans and other mammals, it is important that the water used is free of pyrogen.
4. Mixed Body Weights
Silica, chlorides, calcium, fluorides, magnesium, phosphates, bicarbonates, tubes, nitrates and allied substances are all kinds of impure ions.
5. Ingredients of Pollutant
This is based on the deterioration of animals and plants, in addition to any human activities including the introduction of alcohol, protein, pesticides, chloramine, herbicides or environmental cleansers.
6. Spilled Gases
Water contains naturally dissolved carbon dioxide, nitrogen and oxygen, but these gases can alter the pH of lab water, which raises the ionic balance. The administration of oxygen and nitrogen can affect the rate of biochemical reactions; excessive saturation of dissolved gases can cause bubble formation, which interferes with their flow through column chromatography and microbial channels.

Explanation:
Cholera
Guinea worm disease
Typhoid
Legionella
Dysentery
Malaria – most commonly associated with mosquitoes and germs in contaminated water
Waterborne diseases stemming from drinking contaminated water result in a staggering 3.4 million deaths each year. The problem is so significant that the Center for Disease Control and Prevention (CDC) even has a special department that deals with contaminated water in the United States. They also network with the World Health Organization (WHO) to provide pure water and treatment solutions for developing nations.
