Transcript of Water Pollution Project

Pollution is caused by food, wood, chemical, textile, glass, tourism and clay industries. For example, tourism affects the water because the visitors pollute the water with mercury or arsenic. Mercury and arsenic are also caused by factories. Mercury is bad because it causes mercury poisoning, which leads to damage in the brain, kidneys, or lungs. Arsenic can cause illnesses or even death. Obstacle 1 Obstacle 2 Obstacle 3 Goal Start How much water is on the planet? Water is mostly used for agricultural purposes. They use 30 bcm (billion cubic meters) annually.
They probably use the water for watering the crops. What are fertilizers? Does Italy use fertilizers or pesticides? How does it affect local ecosystems? Water Pollution Project By You-Been Lee Explain how agriculture affects the water in Italy. Explain how industry affects the water in Italy. What are the most common uses of water in Italy? Why are these the common uses? Fertilizers are something that are added to the soil to make the soil more nutritious. Explain how mining affects the water in Italy. What is sewage? How is sewage treated (gotten rid of) in Italy? About 70% of Earth. How much water is fresh/drinkable? About 2 percent of the planet's water is fresh but 1.6% is in ice caps and glaciers. Only about 0.36% of water is found in lakes and rivers. http://science.howstuffworks.com/environmental/earth/geophysics/question157.htm References Country: Italy Some examples would be fertilizing, which causes runoff of nutrients in the water and fish killing. Irrigation (when people dig into the ground to find water) causes bioaccumulation in edible fish. http://www.fao.org/docrep/W2598E/w2598e04.htm#agricultural impacts on water quality Question 1: Question 2: Question 3: http://www.informaction.org/index.php?main=waterpol_gen&s=Water%20sewage http://en.wikipedia.org/wiki/Mercury_poisoning http://www.bbc.co.uk/health/physical_health/conditions/arsenic_poisoning.shtml When we mine, water mixes with coal and other rocks underground and the water becomes toxic. The toxic water contaminates groundwater, streams, plants, animals, and humans. It makes the water undrinkable or it kills animals. Question 4: http://www.greenpeace.org/international/en/campaigns/climate-change/coal/Mining-impacts/?accept=31890dad94f68a15a59051c43738475d http://www1.american.edu/ted/projects/tedcross/xseap17.htm Question 5: http://www.icid.org/v_italy.pdf Sewage is waste that is carried by water. In Venice, the sewage goes to the canals. And then the tides take it out to the ocean. What are pesticides? Pesticides are something that are added to crops so that pests/bugs don't eat it. Italy does use fertilizers and pesticides. There's this type of pesticide that makes surface water very nutritious and makes groundwater polluted by nitrates. Nitrates can affect red blood cells. Babies can turn blue if they consume nitrates. What is bioaccumulation? Question 6: http://www.fodors.com/community/europe/dumb-question-about-what-happens-to-the-sewage-in-venice.cfm http://en.wikipedia.org/wiki/Sewage Queston 8: http://www.sinoitaenvironment.org/ReadNewsex1.asp?NewsID=2616 http://www.wheatleyriver.ca/wrig-pilot-nitrate-study/nitrates-and-their-effect-on-water-quality-a-quick-study/ http://www.pan-uk.org/pestnews/Issue/pn39/pn39p18.htm Bioaccumulation is when a chemical (like pesticides or fertilizer) goes into an organism's body and then another organism eats that organism and then ANOTHER organism eats THAT organism and the chemical gets passed on. For example, let's say that somehow, pesticides got inside a small fish's body. And then a bigger fish ate that fish. And then a fisherman fishes the fish and we eat it. The chemicals in the pesticides are passed on when the organism eats the other organism. So eventually, we have the chemicals in our body and we get sick. What do YOU think about bioaccumulation? WHY? I think it's bad because when those chemicals come to us, humans, we can get sick. Explain why the water cycle is important for life on Earth. I think that it is important because we will only have salty water (which is obviously undrinkable), if there was no water cycle, because the water in the river goes to the sea and there will be no water left in the river. The only water left would be salty water and since we can't drink that, we will die.
