Water & Health

Meliputi > 70% dari permukaan tanah Water pollution mempengaruhi drinking water, rivers, lakes and oceans.

Sumber Polusi Point source Non point source Jenis-Jenis Polusi Air – Polusi air permukaan – Polusi air dalam tanah – Polusi mikroba, kimia, nutrient, suspended matter, oxygen depleting

Jenis Pollutants Heavy metals from industries accumulate in nearby lakes and rivers: Toxic to marine fish and shellfishes, humans eating them: Birth defects & Carcinogenic

Industrial waste, Toxic compounds  damage the health of aquatic animals and those who eat them. Some have a mild effect, other can be fatal. Cause: – Immune suppression – Reproductive failure – Acute poisoning

Microbial pollutants from sewage  infectious diseases  aquatic life and terrestrial life through drinking water. – Cholera – Typhoid fever – Infant mortality. Organic matter and nutrients  increase in aerobic algae and depletes oxygen from the water  poor oxygen content  death fish and other aquatic organisms

Sulfate particles from acid rain  harm the health of marine life  mortality. Suspended particles  mengurangi – The quality of drinking water for humans – The aquatic environment for marine life. – The amount of sunlight penetrating the water. – Disrupting the growth of photosynthetic organisms
