Construction sites are an example of non-point sources. Non-point sources are sources of pollution in which pollutants are diffuse and originate from no specific location. These sites often act as a source of pollution in which those certain pollutants are not specific only to this construction site they originated from elsewhere.
Here, the excessive amounts of nitrates and phosphates coming from sewage and runoffs are causing decomposition of organic matter; this leads to algal bloom. In time the algae dies and the decomposition of the algae leads to low oxygen levels.This leads to the death or injury of aquatic animals. Now I know why nitrates and phosphates can be dangerous.
Ms Olson also told us that the strong smell of decay is often an indication that this process is occurring.
The process of liming has currently occurred here. The plane above just released calcium carbonate into the waters which neutralizes the acid in the lake. Even though this process seems to work its practically impossible for it to be 100% effective. Rivers feed acids to lakes continuously as its a continuous process (rivers carry water into lakes), because of this we would need to constantly lime lakes which is really expensive but its also in- effective since the lakes would just get acid in them again. Ms Olson said that the concept of liming will be a bonus mark on the test.
Today, I went to the science exhibit and I learned a bit of the Ozone layer and how its affected by CFCs.
The Ozone Layer is a layer of the Earth that shelters us from the harmful UV light (ultraviolet light). We could think of the ozone layer as sunscreen, protecting us from the UV light. I learned that CFCs (Chlorofluorocarbons) are a human made pollutant that has hand many harmful effects towards us. When it was first discovered CFC's were useful, non-toxic, cheap, and stable; so we saw it as a friendly resource. But a few years back we learned the real affects of CFCs. CFCs react with ultraviolet light to produce chloride ions which then act as a catalyst for the breakdown of ozone gas (o3) into regular oxygen gas (o2). This can cause the ozone layer to break down and the dangerous UV light can pass through and affect us. Because of this fear 81 countries have decided to not use CFCs to make sure the ozone layer does not break down. Now I'm ready as the two bonus concepts; liming and CFCs are now familiar to me.
TIME TO TAKE THE TEST AND INCORPORATE WHAT I HAVE LEARNED.
What, I FAILED. Well I guess I wouldn't have failed if Ms Olson wouldn't had said "ARE YOU SURE" every single time I answered.
Get ready for your oral examination!
Oh Well
