cadmium-Copper

SLiM & Eddie!

The chemical that I researched is called Cadmium. A well known use for Cadmium is keeping alloys (metals?) together with low melting points. it is also used in batteries as many different times of solder. compounds of Cadmium are used for black and white television phosphors and the green and blue phosphors in color TV's. As a yellow pigment Cadmium sulfide is used. The compounds of Cadmium are toxic. Cadmium is used in countries like Australia, Belgium, Canada, Denmark, European Union, and basically all over the world. They mostly use it for making batteries for all sorts of things. usually that requires batteries and what not. Cadmium is most exposed to human through fertilizer about 33%.

Cadmium is toxic so its an automatic health hazard for humans. Up to date there hasn't been any proof of Cadmium causing anything wrong with the human body. therefore make it questionable as to weather its hazardous or not. Cadmium will effect people in a Gastrointestinal, pulmonary, and dermal way. dermal meaning cuticular also meaning cuticle meaning a fingernail.(had to research that). The way we usually get Cadmium in our pulmonary system is through cigarettes (like always) and our lungs absorb 40-60% of the cadmium in the tobacco. x_x. a nonsmoker had the cadmium level of 15 mg. while a life long smoker had the cadmium level of 30 mg. people who work with cadmium develop ARDS which means acute respiratory distress syndrome. That basically is bad coughing in a sense. When the cadmium that was breathed in reaches the blood is takes the form of a crystal structure. Cadmium cant be totally ex sponged from the body but it can be reduced by not smoking (no surprise there) or not working in a factory that deals with cadmium Cadmium is made in two different ways. Man-made processing, and naturally in the wild. It can be found naturally near the Vilyuy River basin in Siberia, and in some zinc ores. it is found in man-made items such as rechargeable nickel-cadmium batteries, cadmium pigmented plastics, ceramics, glasses, paints and enamels. Cadmium cerium orthophosphate Cd0.5Ce2(PO4)3 is synthesized by precipitation from aqueous solutions.

Cd + NO3– → Cd++ + NO 3 Cd + 8 (H+ NO3–) → 3 Cd++ + 6 NO3– + 2 NO + 4 H2O (not in lowest terms) 3 Cd + 8 H+ + 2 NO3– → 3 Cd++ + 2 NO + 4 H2O (lowest terms)

The synthesis of cadmium oxide from a gel of cadmium hydroxide has been followed using unique combinations of X-ray diffraction. X-ray absorption fine structure. Spectroscopy, and small-angle X-ray scattering. XRD and XAFS enable the crystallography, particle size, and local structure to be quantified as the hydroxyl gel converts into cadmium oxide around 182°c. SAXS measures the evolving microstructure, with cadmium oxide growing dendritically in a fractal geometry, initially from rough nano-particles. Major growth and densification takes place between 325 and 550°c. The implications for characterizing the precipitation of cadmium oxide nano-particles in zeolitic hosts are considered.

If the chemical Cadmium were banned then it wouldn't help us out either way. It's like if Cadmium is used to hold metals together and it was taken away then they would have to find something else to be used like Cadmium was used. For all we know the next chemical will be more dangerous then the Cadmium was. Then the next chemical might not even work as well as Cadmium was working and it might cost people money because they can't produce the things they would be able to because of no Cadmium. We would lose a lot of things like batteries. That right there speaks for over a million things right there that require batteries. Some places that export cadmium are South Africa and New Zealand. If this chemical was banned then for the human health it would be better. Cadmium basically causes the same results as smoking. Without it would in term help our lungs. Banning this chemical according to political things say that its already banned in most parts of the country and it is being replaced by nickel-metal hydride. So I guess it hasn’t been affecting us that much.
