1 B ASIC TYPES OF WATER POLLUTION Táňa Macková

2 OXYGEN DEPLETION POLLUTION o Microorganisms that thrive in water feed on biodegradable substances. o When there is an influx of biodegradable material from such things as waste or erosion from farming, the numbers of these microorganisms increase and utilize the obtainable oxygen.

3 OXYGEN DEPLETION POLLUTION When these oxygen levels are depleted, harmless aerobic microorganisms die and anaerobic microorganisms thrive. Some of these organisms produce damaging toxins like sulfide and ammonia.

4 N UTRIENT POLLUTION Nutrients are usually found in wastewater and fertilizers. These can cause excess vegetation in the water such as algae and weeds, using up the oxygen in the water and hurting the surrounding marine life and other organisms in the water.
