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
