How Types Of Contaminants Get There, How To Reduce It, And How To Clean It Up

Question 1

Toxic pollution

Answer 1

Toxic pollutants are chemicals that can cause disease, death, birth defects when ingested or absorbed by organisms. Toxic pollutants range from common household chemicals to industrial chemicals and mining wastes. The effects of toxic pollutants vary widely.

Question 2

Sediment pollution

Answer 2

Sediment pollution is caused by the erosion of soil into waterways, usually during heavy rain. Sediments pile up in reservoirs, rivers, and harbours, destroy fish, wildlife habitat, and cloud the water, blocking sunlight and interfering with aquatic plants.

Question 3

Nutrient pollution

Answer 3

Nutrient pollution is the process of excessive nutirents in water. High concentrations of nutirents such as nitrogen and phosphous can promote explosive algal growth aaand eutrophication. When the algae die, the process of decomposition consumes oxygen and leads to a state of hypoxia, or low-oxygen conditions, killing fish and other aquatic organisms.

Question 4

Bacterial pollution

Answer 4

Bacteria are tiny organisms that often aid in pollution control by breaking down the organic matter in sewage, oil spills, or other pollutants. Bacteria can cause problems when untreated human or animal waste are released directly into water resources. Drinking water contaminated with bacteria may lead to outbreaks of cholera or dysentery. Fecal bacteria cause health problems or animals and plants aw well.
