State the harmful effects of water pollution
Answers
Answer:
How does water pollution affect humans? Try drinking untreated water nowadays and your body will immediately react to it. You will get a stomach ache at the least. Water-borne diseases account for the deaths of 3,575,000 people a year! That’s equivalent to a jumbo jet crashing every hour, and the majority of these are children.
Infectious diseases can be spread through contaminated water. Some of these water-borne diseases are Typhoid, Cholera, Paratyphoid Fever, Dysentery, Jaundice, Amoebiasis and Malaria.
Chemicals in the water also have negative effects on our health.
Pesticides – can damage the nervous system and cause cancer because of the carbonates and organophosphates that they contain. Chlorides can cause reproductive and endocrinal damage.
Nitrates – are especially dangerous to babies that drink formula milk. It restricts the amount of oxygen in the brain and cause the “blue baby” syndrome.
Lead – can accumulate in the body and damage the central nervous system.
Arsenic – causes liver damage, skin cancer and vascular diseases
Flourides - in excessive amounts can make your teeth yellow and cause damage to the spinal cord.
Petrochemicals – even with very low exposure, can cause cancer.
