15 Questions on Non-Point and Point Source Pollution Eric Angat Teacher
Alternative Energy creates less Pollution compared to fossil fuel. Fossil Fuel
What is Pollution? Pollution is the introduction of a contaminant into the environment. It is created mostly by human actions, but can also be a result of natural disasters. Pollution has a damaging effect on any living organism in an environment.
Two types of Pollution Sources 1. Non-point source pollution – pollution from wide variety of sources. 2. Point source pollution -pollution from a specific source
1. Non point source pollution Examples: motor oil, antifreeze, cosmetics, salts added on roads during winter, excess fertilizer. Anything that is picked up
2. Point source pollution – Examples: factories and power plants You know exactly where the pollution is coming from.
Point Source Pollution coming from a known source.
You know that the oil spill came from the tanker. This Point Source Pollution.
You do not really know who threw these plastics and other trash or where they came from. They were brought to the lake or ocean by runoff This Non-Point Source Pollution. .
You do not really know where or who threw this plastics and other trash. They were brought to the lake by runoff This.
You do not really know whose car leaked oil. Oil from car parks are washed by runoff and brought to lakes. This is Non-Point Source Pollution.
Non-point source pollution Litter, motor oil leak, CO 2, plastics, chemicals All these pollution mixed together and carried by runoff to the rivers, lakes, and ocean. Excess fertilizaer Animal waste
Nonpoint Source Pollution 1. What is the biggest source of water pollution? 2. What is non-point source pollution? 3. How does nonpoint source pollution get in our water? 4. Where does nonpoint source pollution come from? 5. What are the common causes of nonpoint source pollution?
Nonpoint Source Pollution https: //www. youtube. com/watch? v=phm. N-Ip. R 3 xw
Nonpoint Source Pollution 1. What is the biggest source of water pollution? Backyards, parking lots and farms. 2. What is non-point source pollution? Pollution from wide source. 3. How does nonpoint source pollution get in our water? Run-off brings pollutants to rivers and streams 4. Where does nonpoint source pollution come from? From all of us. That is why we need to reuse, reduce, and recycle. 5. What are the common causes of nonpoint source pollution? Over applying fertilizer, dripping oil, allowing erosion, leaving pet waste.
6. What is an acidic lake? Pollution can turn a lake into an Acidic lake. A healthy lake has a p. H of 6. 5 - 7. When the p. H of the lake become lower than 6. 5 then a lake is acidic. If the acidity is below 4. 5 then all plant and fish would die. http: //www. pbslearningmedia. org/asset/lsps 07_int_acidlake/
7. What is Eutrophication? https: //www. youtube. com/watch? v=6 LAT 1 g. LMPu 4
Eutrophication The process by which a body of water acquires a high concentration of nutrients, especially phosphates and nitrates. That promote excessive growth of algae. As the algae die and decompose, oxygen hungry bacteria turn the body of water anoxic or no oxygen. This causes the fish to die.
Point Source Pollution is from an identifiable source.
Garbage Patch in the Middle of the Ocean 8. How does the garbage end up in the middle of the oceans? 9. How are marine organisms affected by plastics? 10. How are we affected by plastics?
Garbage Patch in the Ocean https: //www. youtube. com/watch? v=St. NZ 3 XUBDYw
Garbage Patch in the Middle of the Ocean 8. How do the garbage end up in the middle of the oceans? Runoff brings plastics to rivers and rivers bring this to the oceans. 9. How are marine organisms affected by plastics? Marine organisms eat the plastics. 10. How are we affected by plastics? We eat marine organisms and the plastics in their muscles and tissues. This is biological magnification!

11. What is an ocean gyre? A gyre is any large system of rotating ocean currents.
An ocean gyre is any large system of rotating ocean currents, particularly those involved with large wind movements. Gyres are caused by the Coriolis Effect
