Chromium 6
What is Chromium 6?
Chromium 6 is a natural metal found in rocks, animals, plants, and soil. It can be carcinogenic (a substance that can cause cancer.) in certain amounts. It is also known as Hexavalent Chromium. Often times it ends up in town's drinking water, due to leaking through the ground.

What is the Chemical Formula?
Chemical Formula: Cr(VI)
What is it used for?
Chromium 6 is used for making paints, inks, dyes, paper, steel, and plastic. It is also used in the production of alloys. Chromium 6 is also used for chrome plating, which allows for some of Chromium 6's properties to be transferred to other objects, usually for its durability properties.
What can it cause?
Chromium 6 can cause many negative effects. If it gets on skin for a period of time, it will cause irritation on the spot. It can cause nosebleeds but more seriously asthma if inhaled. If consumed it can cause kidney and liver damage, as it has no means of exiting the organs once it is consumed. If it comes into contact with teeth, it can degrade the enamel protecting your teeth. Chromium 6 is also a known cause of cancer, most often lung cancer, but can also result in stomach cancer, throat cancer, and uterine cancer if ingested.
Treatment?
While chromium 6 is dangerous, it can be treated once it is ingested. If it gets into water, adding iron sulphate to the water will change it into Chromium 3, which is safe and actually healthy for humans to ingest. Activated carbon can remove 99 percent of chromium 6 in solutions. A certain microorganism can actually decompose Chromium shavings.
Opinion
Our opinion is that Chromium 6 is very dangerous, and as such, water companies should use extra precautions to avoid it ending up in their water systems. This could be done by treating the water with iron sulphate as mentioned before, or better protecting the water system so chromium 6 never has a chance to come in contact with it. We think it should stay in other products, as those products are not usually ingested or heavily inhaled.
