The water pollutants include: fertilizers and pesticides from agricultural production; wastewater and waste from food processing; lead, mercury and other heavy metals; Chemical waste from industries. It leads to many consequences. Almost all types of water pollution are harmful to the health of humans, animals and plants. Heavy metals from industrial processes can accumulate in nearby lakes and rivers. They are toxic to marine organisms such as fish and shellfish, and subsequently to those who eat them.

4Al + 3O2 ---> 2Al2O3
Na2O + H2O ---> 2NaOH
2KMnO4 ---> K2MnO4 + MnO2 + O2
Fe + 2HCl ---> FeCl2 + H2
H2 + CuO ---> Cu + H2O
2Al + 3H2SO4 ---> Al2(SO4)3 + 3H2
To reduce water pollution, we should reduce the use of herbicides, pesticides, and fertilizers, avoid direct dumping into water systems, take action by actively participating in water pollution prevention.
