Antimicrobial Copper at the Society for Environmental Toxicology and Chemistry’s (SETAC) Conference

November 15th, 2011 No comments

By Adam Estelle, CDA Project Engineer

For the second year now, I’ve hosted a booth on Antimicrobial Copper at the Society for Environmental Toxicology and Chemistry’s (SETAC) annual conference.  At first thought, it seemed like putting copper in hospitals was the last thing environmentalists wanted to hear about. However, sharing the public health benefits of copper with this group has been both beneficial and enlightening.  Read more…

Copper: Essential Nutrient (Part 3 of 3)

Hemocyanin
Assortment of nutsAll humans need iron for healthy red blood cells. It is an integral part of hemoglobin, and carries oxygen around our bodies, literally helping our organs and muscles to “breathe”.

Other species, however, use a different metal for this job. Crustaceans, which include crabs, lobsters, crayfish, and shrimp, use copper to bind and transport oxygen. Their “hemoglobin” is called hemocyanin, and their blood is not red, but greenish in color.

Your favorite crustaceans are not the only ones who use copper as an oxygen carrier; so does that famous extrMr. Spockaterrestrial, Mr. Spock. Being half-Human and half-Vulcan, the USS Enterprise’s first officer uses both hemoglobin (the iron carrier) and hemocyanin (the copper carrier) to breathe, and like earth’s crustaceans, he has green blood.

Remember, the U.S. National Academy of Sciences recommends that we humans get at least 1 mg of copper per day, by eating seafood, legumes, nuts, or chocolate.

Live long and prosper!

Copper: Essential Nutrient (Part 2 of 3)

Nutrition labelThe healthy trio: iron, zinc, and copper
Everyone knows about the need to get enough iron and zinc in their diet. In fact, many people take zinc supplements when they want to boost their immune systems. What most people don’t know, however, is that copper is equally important for health and the immune system, and that too much zinc can make it difficult for the body to obtain enough copper.

Copper is needed for the formation of blood cells and for neurological health. People who overdose on zinc supplements for many years can develop anemia and neurological symptoms, such as gait abnormalities. Usually, these symptoms are reversible with a proper balance of zinc and copper.

For optimal health with regard to the essential trio of iron, zinc, and copper, we should follow the U.S. National Academy of Sciences guideline: Anyone (in any age group) who takes an iron supplement of 30 mg or more per day should, under the supervision of a physician, balance it with about 15 mg of zinc and 2 mg of copper. Moreover, pregnant women should consult with their physicians to ensure that their prenatal supplements contain the proper balance of iron, zinc, and copper.

Most people know that copper “runs our lives” by conducting electricity and heat. But did you know that copper occurs naturally in our bodies Mother feeding her babyas a life-sustaining essential nutrient?

Every body needs copper for blood vessel formation for a healthy heart, for stabilizing the connective tissue, which binds one part of the body to another, and for healthy bones and teeth. Copper is also needed for brain development and for effective communication between nerve cells in the brain.

In fact, copper is so important to our health that the absence of it can cause death. This is the case in a rare genetic disorder called Menkes disease: Menkes patients cannot absorb copper from food into their bodies, and sadly they die before they reach toddler age. There is no Bowls of legumestreatment for Menkes disease at this time, and research is underway to find a way to supply copper to these patients effectively.

Most people, however, can absorb copper, which is plentiful in a variety of the foods we eat every day, such as shellfish, nuts, legumes, mushrooms, barley, cooked tomato products, liver, and even chocolate.

Copper in Architecture Awards – 2009

August 17th, 2009 1 comment

Richmond Center for Visual ArtsThe 2009 winners of the North American Copper in Architecture  (NACIA) Awards were announced this month and they do not disappoint. Twelve outstanding projects – nine from the United States and three from Canada – made the cut. They represent the best in both new construction and renovation, and include a Native American-inspired residential compound, an Ontario health center, a major New Jersey boat terminal, a visual arts complex in western Michigan, an Arizona golf facility, and a historic New York courthouse.

The NACIA Awards program, sponsored by the Copper Development Association (CDA) and the Canadian Copper & Brass Development Association (CCBDA), recognizes North American building projects that demonstrate an outstanding use of architectural copper and copper alloys.

Each of the 2009 finalists was selected for its excellence in craftsmanship, attention to detail, and architectural vision. Seen together, they show the amazing range of color, texture, finish, and form that is possible with copper. Over time, they will prove with their durability and timeless beauty the wisdom of choosing this most versatile natural resource.

The CDA has posted a slide show and project description for each of the 2009 winners.

Would you like to nominate an outstanding copper building project? The call for entries for the 2010 North American Copper in Architecture Awards is now open. Submissions will be accepted through January 31, 2010.

Copper FAQs, Resources, and Upcoming Events

“…Then, there’s copper, which is the only pipe I use. It costs money. It costs money because it saves money.” – Cosmo Castorini, Moonstruck

If you’re not already working on a project that includes copper, chances are you soon will be. Copper is back in a big way and for good reasoncopperroofbldg.225w: it’s beautiful, durable, 100% recyclable – and it saves money.

The Copper Development Association has an informative page, Architectural Copper Products FAQs, to get you started. Learn about copper finishes, corrosion and stain prevention, environmental impact, and proven design techniques for working with copper and its alloys.

Our industry experts can help in a variety of ways, from in-house seminars to project design assistance, document and specifications review, and contractor recommendation.
