http://www.treehugger.com/clean-technology/removing-arsenic-from-water-withplastic-bottles-and-nutrition-supplements.html?campaign=th_rssPicture: This picture shows a plastic water bottle sitting in a body of water. This represents the water bottle that can remove the arsenic.
Summary: When people think of water bottles, they think of a serious problem. Well, scientists are saying that plastic water bottles can get rid of some arsenic in the water and make it clean water. The American Chemical Society reports that more that 100 million people are exposed to very high levels of arsenic in their drinking water. With this simple technology, we can fix that. Areas such as India, Bangladesh, and other southeast Asian countries are at an encounter with arseninc in their drinking water. The scientists have a method when it comes to taking arsenic out of the water. First they coat pieces of the plastic water bottles with cystiene- an amino acid found in dietary supplements and foods. Then stur the plastic in the contaminated water. This works like a magnet. All the arsenic in the water sticks to the plastic and you just pull out the plastic and the water is safe to drink.
Opinion/Reflection: I think this a great way to recycle all our used water bottles. So many people just litter or throw out water bottles. You could donate these and save some less fourtunate people. Whoever found out this method should get a lot of credit and fame. Arsenic is a very dangerous substance and can harm the human body as learned in class. I can connect to this because we learned about the Indian people who have high levels of arsenic in their water and I saw the man with the messed up feet and hands.
Questions:
1) How do you think this was method was discovered?
2) Do you think this is going to save a lot of people? Why or why not?
3)Why do you think these certain people/countries have aresenic in their water supply?
Opinion/Reflection: I think it is really great that they have found a simple and hopefully inexpensive way to remove arsenic from contaminated waters. I agree with Ryan when he said that it is a great way to use and recycle the water bottles. I remember doing the assignment where we were researching about India's high levels of contaminates and all of the diseases that they get from the water. Hopefully we can get this to all the countries who need to get arsenic out of their water.
ReplyDeleteAnswers to Questions:
1. I think that this method could've been discovered by scientists who were trying to find eco friendly ways to help remove contaminates.
2. Yes, because since arsenic is causing so many diseases then that means less disease when you take it out.
3. They have dug their hole to get filtered water too shallow.
Questions:
1. When will this project start?
2. Is this expensive to do?

ReplyDeleteUmm even though sam did this....
ReplyDeleteOpinion/reflection: I think that this is really intriguing. Who knew something as simple as this could be possible. Like mentioned, this would be a perfect thing to use and say that we actually made use of the plastic before we throw out or recycle it. This seems like q cheap way to remove arsenic but still may cause pollution problems if the plastic was to be accidentally left over and not retrieved. Other than that this is great to use and clean the waters of worldwide streams, lakes and such contaminated with arsenic. Now we can remember this if we were in any need of cleaning arsenic contaminated water in the future.
Answering questions: 1) I think this was either found by scientists who purposely searched for an easy green way to remove arsenic (like Brittany mentioned) or by someone randomly stumbling upon it. These are the ways things like this are found. 2) Yes this will help many people because there are many water contamination problems in poorer countries and this cheap way to remove contaminants will be easy to afford. 3) Well it is know that arsenic is from soil so in certain countries people may have accidentally mixed water and soil together. One way of this happening is digging shallow wells and such or orchard spraying.
Questions: 1) Do you think that we will ever need to use this technique in America or Pennsylvania in the future? Why or why not?
2) If this technique was not found than who would be affected and why?
3) How come people drink this arsenic contaminated water? Do you think they are not aware of the symptoms or they do not know it is there?
Opinion/Reflection: Even though sam already did this article, I think that it is a great way to remove arsenic from contaminated water. We should get the other countries to use this method to remove arsenic. It's a great way to use plastic bottles. They would have to be recycled after that though. This reminds me of learning about all of the countries and how all they have is contaminated water. This method could help them.
ReplyDeleteAnswers to questions:
1. This could have been discovered by scientists trying to test contaminated water.
2. Yes, because arsenic is a dangerous contaminant that causes diseases.
3. Digging shallow wells and they dont get their water filtered.
Questions:
1. If countries don't use this method, will they find any other methods?
2. Will this be too expensive for the countries to afford?
Okay because I already did this...I'm just going to post my opinion/reflection from when i did the article
ReplyDeleteOpinion/Reflection: THIS IS THE COOLEST THING EVER! When I first saw the headline, I figured it was a super complex way that wouldn't work...but I guess it does! I think this is awesome, especailly for the people who need it in developing countries. There are 100 million people with poisoned water due to arsenic. These people have probably been drinking water from bottles, so they should have plenty around. Developing countries don't have money laying around to clean their water, so this practically free way is awesome for them. My personal connection to this could be that if we ever had our water polluted with arsenic or I was somewhere where the arsenic levels were a problem, I could clean it myself to make it drinkable.
Answers:
1)I think it was discovered by testing out different methods, or even by accident.
2)I think this could save a lot of people because it is so inexpensive and you can find water bottles whenever. Although nutrition supplements could be harder to find, it is still cheap and easy.
3)I think certain people have arsenic in their water because arsenic can come from erosion of natural deposits; runoff from orchards; and runoff from glass & electronics production wastes.
Some cool follow-up websites on arsenic in water:
http://water.epa.gov/drink/contaminants/basicinformation/arsenic.cfm#How%20does%20arsenic%20get%20into%20my%20drinking%20water? is the epa's website, which has tons of great infomation
http://www.youtube.com/watch?v=kPlPav5IT1A this is a sad video about how Myanmar water is polluted by arsenic
