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 by runoff.

2. Point source pollution – Examples : factories and power plant s You know exactly where the pollution is coming from.

Point Source Pollution 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 Non-Point Source Pollution.

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.

Litter, motor oil leak, CO2, plastics, chemicals Excess fertilizaer Animal waste All these pollution mixed together and carried by runoff to the rivers,lakes, and ocean. Non-point source pollution

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

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? Farms ( agriculture), backyards, and parking lots. Pollution from wide source. Transported by runoff. Run-off brings pollutants to rivers and streams From all of us. That is why we need to reuse, reduce, and recycle. 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 pH of When the pH 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.

7. What is Eutrophication?

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

Garbage Patch in the Middle of the Ocean 8. How do 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? Runoff brings plastics to rivers and rivers bring this to the oceans. Marine organisms eat the plastics. We eat marine organisms and the plastics in their muscles and tissues. This is biological magnification!

An ocean gyre is any large system of rotating ocean currents, particularly those involved with large wind movements. Gyres are caused by the Coriolis Effectocean currentswindCoriolis Effect

12. Where does your litter go?

Litter consists of waste products that have been disposed improperly, without consent, at an inappropriate location. waste products

Aerosols fridge Air conditioners CFC from these sources are examples of non- point source pollution.

13. Which can lead to the depletion of the ozone layer of Earth? A. coal-fired power plants B. vehicle exhaust C. burning compost D. aerosols

Water vapor Carbon dioxide is a greenhouse gas Uranium-fuel of nuclear power plant Coal-fuel of coal plant Radiation danger

Or suffer the consequences. Carbon dioxide is an example of non-point source pollution.

14. Since 1901, global surface temperatures have risen at an average rate of 0.13°F every ten years. In which way could the average increase in global temperatures influence Earth? A.by decreasing erosion within coastal ecosystems B.by decreasing periods of drought in all water systems C.by increasing the amount of flooding because of rising sea levels D.by increasing the formation of sea ice within polar regions

Hydroelectric in Dam Which causes pollution? Reforestation Nuclear Power

15. Which is a major source of air pollution created by humans? A. hydroelectric plants B. industrial factories C. reforestation D. nuclear power
