It is well know that heavy metals (defined as natural metallic elements with a volume density below 5g/cm, like lead, zinc, cadmium or nickel) are naturally present in the water, the air and the ground in tiny concentrations (a few ppb). However human activities contribute to spread them in the environment (nickel is commonly used to make coins or orthodontic braces for example), leading to abnormally high concentrations in the ecosystems. Beyond their features, heavy metals aren’t biodegradable and accumulate themselves in life organisms, becoming more and more toxic. </p></br></br></div>

First of all, you must know heavy metals are defined as natural metallic elements with a volume density below 5g/cm, like lead, zinc, cadmium or nickel. It is well know that heavy metals are naturally present in the water, the air and the ground in tiny concentrations (a few ppb). However, human activities contribute to spread them in the environment (nickel is commonly used to make coins or orthodontic braces for example), leading to abnormally high concentrations in the ecosystems. As you may know, heavy metals aren’t biodegradable and accumulate in alive organisms, becoming more and more toxic. </p></br></br></div>

Nickel can damage nature, plants, algae, when rain includes high concentration of metal. To understand environmental issues at a city scale, our team went to visit a water treatment plant to know more about rules and controls of heavy metals in the water. Astonishingly, there is no control of heavy metals concentrations whereas these pollutants are absorbed on matter suspension and eliminated in sludge. So nickel is in the environment and can be found in the water we use.</p></br>

Concerning recycling, nickel stocks don’t exceed sixty years. It is present in Australia, Russia,  Canada, New Zealand, Cuba. 60% are used to create inox. There is necessity to protect stocks and to improve their utilization. Actually, nickel is recycled at 55%.</br> In France, researchs (labex Ressources 21 with Baptiste Laubie) are direct on nickel with the aim of study strategic element and recycling process. Nickel has a big economic importance and it is necessary to focus on news deposits considering that impacts of the biosphere. Our project interest this research worker as part of development.</p></br>

As far as recycling is concerned, nickel stocks don’t exceed sixty years. These stocks are present in Australia, Russia,  Canada, New Zealand, Cuba. 60% are used to create inox. Protecting stocks and improving their use is necessary. Nowadays, nickel is recycled at 55%.</br> In France, there are some Nickel directed research projects (labex Ressources 21 with Baptiste Laubie) that aim to study strategic elements and the recycling process. Nickel has a big economic importance and it is necessary to focus on news ways of stocking it considering its impact on the biosphere.</p></br>

Curly'on - IGEM 2014 INSA-LYON

Our human practices include an original approach of social sciences and design.

  • Heavy metals, environmental and health issues


  • CurLy'on in 2030?


  • Prototype
