__**Cadmium**__ Onji and Lena

=Abstract:= ==Cadmium is an element that can be found in the earth. You can find most findings of cadmium in the earth crust also on Volcano’s. Germany of 1817 is when they found it. They started using it in different products in the 19th and 20th century using in products such as sprays for telephone cords and jewelry and rechargeable batteries.== ==Possible risk factor of being exposed to cadmium would be lungs and prostate cancer, and poisoning. It can affect the whole human system like the kidneys and bones, which may be cause by cigarettes. This connects to environment and how cadmium can affect the “circle of life” is because when we smoke it does not affect us at first it goes into the plants and animals and they get sick and maybe die, we eat them and we get sick.== ==The fact that it cannot degrade is very important because we as people have to remember to recycle it properly. Most big countries have banned cadmium. The cost of alternative can be cheap by using zinc and aluminum. Understanding that this cadmium is super useful in a painters life and if it’s gone painters will be affected. Without this chemical we would still be looking for other resources for things like rechargeable batteries. Some of the things that we use for cadmium is useful maybe if we get rid of certain things that are not useful with cadmium in them like cigarettes maybe the levels of cadmium can not be as high.==

=Background =

It’s not banned but it can cause cancer.
=Human health implications (Cadmium) = -What are the possible dangers associated with this chemical? • Could cause lung or prostate cancer • By inhaling this you can get acute poisoning • For extreme exposure it can severely effect the lungs, kidneys, and the bones. -How, specifically, does this chemical affect the body? It usually specifically targets the kidneys and can last in the kidneys for 20 to 30 years. It is found in cigarettes. For non-smokers the chemical is usually in foods, the daily dose is usually 10 to 25 ug though for smokers it is twice this amount. -What human body processes are affected by this chemical? The kidneys*, bones, and lungs -What human systems are affected by this chemical? (eg reproductive, endocrine) skeletal system and the organ (urinary/excretory) system -Include chemical reactions that take place in the body. Individually, cadmium, when it enters the human body it will go into the “pathways” of the food chain. Cadmium comes from “terrestrial foods” which means, foods that have been grown in soil with plants or meat in which the animal has eaten soil with plants.

**Environment Implications** -What specific environmental systems/processes does your chemical interact with? Soil is a big part of Cadmium so is Animals and it is not that much levels of Cadmium in animals. There was an abundance of Cadmium supply in our Agricultural Soil as well and found it in most farm who produce fruits, vegetables, and meat. But the ___ said it was not a big deal.

-How does the chemical interacts with the environment? Well some of cadmium comes from tobacco smoke which goes into the earth which goes into the animals and the plants which leads back to the contamination of Humans so it could mess up the “circle of life”

-What happens when this chemical degrades? What byproducts are formed? This particular chemical cannot degrade nor be destroyed.

-How long does it take to degrade?

It cannot degrade -How is it disposed of? //Well most of cadmium is in batteries they are 100%//

//-Include at least 3 balanced chemical reactions.// 2Cd(s) + O 2 (g) → 2CdO(s) in the air. Cd(s) + H 2 SO 4 (aq) → Cd 2+ (aq) + SO 42- (aq) + H 2 (g)- in dilutes sulfiric acid Cd(s) + F 2 (g) → CdF 2 (s)- In halogens (it turns white)

Every chemical has its pro and cons and some of those kinds of pro’s can lead into banning of that chemical. Cadmium is a very toxic chemical and we use them in our everyday life’s. We smoke it we eat it and we even put it in our cell phones. However if banning this we will have to find a new and probably less active chemical to try to compare to cadmium. Yes some of its purposes of this such as the cigarettes we can try to eliminate that part of them. Cadmium is useful for coating this also has a very low electrical resistance. People in the business of metal coating are being let down because people are trying not to use this because of our environment, but sometimes we need this because it helps things last longer. The environment isn’t going anywhere and people need to think how will not having cadmium affect their everyday life’s
