__**Abstract **__
 PCBs belong to a wide-ranged family of man-made organic chemicals known as chlorinated hydrocarbons. They were manufactured only for 50 years domestically. From 1929 to them being banned in the United States in 1979. They have many ranges of how toxic they come be, from the lowest to the highest. Some can be light as the shade yellow on a sunny summer day to a dark winter night. They are used in many different industrial things such as oil-based paint, carbonless copy paper, cable installattions, dyes, and the oil used in some motors. A company that is well known an use PCB’s is Arcoclor. PCB’s are nonflammable, highboiling point, electrical insulating chemicals.

When PCB’s are exposed to us humans there is a major effect the tend to leave. It can cause us to have cancer. It can also mess up the operation of the endocrine system, the reproductive system, and the immune system. Which all three systems are important to us. When PCB’s are exposed to our environment it can go along way because the littlier the amount of the chemical the farther it can travel and can be found in the sea which then can affect any aquatic animals such as fish. We the human eat the fish as well. When is in the atmosphere it is hard for the chemical to leave the air at the time. The government find these chemicals to be highly unbenefical to the people so they decided to band them

Since PCB’s are no longer used in the United States I find that to way better. It has too many downfalls to the fact once exposed it is kind of hard for you to get rid of it. Which effects our whole life food chain. I think that Canada should ban it as well. Im sure there are other chemicals that we can use that can play a role in the economy. As you can see now that we use a new chemical in our paint to make it not so much hazardous to use such as on car paint we use silicon which is not the bad as PCB’s.  __**Health and Enviromental Sections**__ -What are the possible dangers associated with this chemical? Some possible dangers associated with this chemical is that if in your food it would expose people to health risk/ when exposed to the skin, irritants when contact is of short duration. With prolonged contact, this may result in a form of dermatitis known as cloracne. Could damage the eyes id exposed to it, googles should be worn.

-How, specifically, does this chemical affect the body? PCB’s are moderate skin irritants when contact is of short duration. With prolonged contact, this may result in a form of dermatitis known as cloracne. If the eyes have been exposed to liquid PCB, it could cause blindness. In addition to causing irritation to eyes, exposure to high concentrations of PCB vapors can create problems to the nose and upper respiratory tract as well as internal reactions.

-What human body processes are affected by this chemical? The main human body processes that PCB are not listed.

-What human systems are affected by this chemical? (eg reproductive, endocrine) The main human body system that is affected by this chemical is the respiratory system.

-Include chemical reactions that take place in the body. N/A

-What specific environmental systems/processes does your chemical interact with? Completely colorless to light, polychlorinated biphenyls (PCBs) are a compound mixture of over 200 different congeners.

-How does the chemical interacts with the environment? PCBs do not readily break down in the environment and thus may remain there for very long periods of time. PCBs can travel long distances in the air and be deposited in areas far away from where they were released.

-What happens when this chemical degrades? What byproducts are formed? While water contamination can occur, many PCBs dissolve or stick to the bottom sediments or attach themselves to organic particles. Similarly, soil is another compound that PCBs bind to.

-How long does it take to degrade? It takes PCB a few years to degrade.

-How is it disposed of? Manufactures no longer make it. But when it was being manufactured, they would dump it into the enviroment. Now scientist who need it or want to conduct experiments on it, dispose of it in a special, that was not told to us.

-In clude at least 3 balanced chemical reactions. C12H10-xClx

Over View of PCB PCB is a chemical that is no longer used, due to the environmental hazards it causes. Some scientists use it in laboratories to test it along with other chemicals and to do experiments. They expose of it, in their own way that does not affect the environment. PCB is no longer sold to the public; it was banned in the 1970’s. The cost of the chemical was very cheap and showed no signs of harm. They are not flammable, have high electrical resistance, good insulating properties and are very stable even when exposed to heat and pressure. All in all, they seemed to be the perfect oil for use in dielectric fluids, and as insulators for transformers and capacitors. They were actually required for fire departments because they helped control fires, and eliminate them quicker. There is not set price for PCB’s, because it was required in homes around the U.S and in fire departments. People used PCB’S for hydraulic fluids; casting wax; carbonless carbon paper; compressors; heat transfer systems; plasticizers; pigments; adhesives; liquid cooled electric motors; fluorescent light ballasts etc. The price of PCB’s range from $20-hundreds, because of the different uses.

__**PSA Video**__  1. What is the specific health/environment issue you will raise awareness of in your PSA? When PCB’s are exposed to us humans there is a major effect the tend to leave. It can cause us to have cancer. It can also mess up the operation of the endocrine system, the reproductive system, and the immune system.

2. What action do you want the audience to take? To make sure that they understand that tha paint in most fo the homes today have the chemical that is banned. So be careful when you use oil-based paint.

3. List 5 facts to support your argument. They were manufactured only for 50 years domestically. From 1929 to them being banned in the United States in 1979. They have many ranges of how toxic they come be, from the lowest to the highest. When PCB’s are exposed to us humans there is a major effect the tend to leave. It can cause us to have cancer.

4. What could be some arguments against your position or difficulties in solving the problem? How would you respond to those arguments/difficulties? I would try to explain to them that it is banned, and it took years for this to be demolished from American soil. 5. Will you use video or images with voiceover? we will use video, and may use voiceover too.

6. How will you gain the audiences attention at the beginning of your PSA? Include a description of images, voiceover, and/or text. We would use pictures, and good opening to catch their attention such as some nice images or even a mini video clip
