How does polluted water affect health?

Water plays a very important role in human life. However, along with economic development, environmental pollution is increasingly serious, including water pollution. So how does water pollution affect human health? The following article will help you answer that question.

1. Causes of pollution

Water pollution is the general change in water quality, water sources are contaminated, causing danger to humans, industrial production, agriculture, fish farming, rest, entertainment, domestic animals and wildlife.

Water pollution usually has two causes:

- Water pollution of natural origin: Due to rain, melting snow, storms, floods bringing into the water environment dirty waste, harmful organisms and microorganisms including their corpses.

- Water pollution of artificial origin: The process of discharging toxic substances mainly in liquid form such as domestic, industrial, agricultural and traffic waste into the water environment.

2. Health effects

Heavy metals

Heavy metals in water are necessary for living things and humans because they are trace elements that living things need, but at high concentrations they are toxic to humans, causing many serious diseases such as cancer and mutations. What is more heartbreaking is that they are the cause of cancer. Heavy metals in water that affect human health are Ag, Hg, Pb, Arsenic, Zn...

Inorganic compounds

Synthetic organic compounds include fuels, dyes, pesticides, growth stimulants, and additives in pharmaceuticals and foods. These substances are often toxic and have a high biological durability, especially aromatic hydrocarbons that cause strong environmental pollution and have a great impact on human health. This is the cause of chronic poisoning and serious diseases such as bladder cancer, lung cancer, etc.

Bacteria in wastewater

Harmful bacteria in water originate from human and animal waste such as viruses that cause cholera, typhoid and polio. It is the cause of epidemics, spreading dangerous diseases, making epidemics more and more widespread.
