Many members have used or are thinking of using pressure lumber to construct aquarium stands and or racks. Please read this article, first.

CHROMATED COPPER ARESNATE [ CCA ] .... arsenic-treated wood - commonly called " PRESSURE-TREATED-WOOD.

Experts say arsenic - a toxic metal - that is known to cause cancer, even in small doses; is No. 1 on the federal government's list of toxic substances.

It works like a thief in the night. It damages the nervous system and the lungs, kidneys, stomach, liver and other organs, causing vomiting, diarrhea, nausea and cramps; then passes through urine within days, leaving little evidence of the culprit.

In the 1980s, the EPA wanted to make sure every consumer who bought pressure-treated wood got a warning sheet that told them to wear gloves, goggles and a dust mask. But under industry pressure, the agency eventually agreed to a voluntary warning program both sides now agree was a widespread failure.

Avoid exposure to sawdust.

Toxicologists say normal arsenic levels in urine are below 50 parts per billion. Levels above 200 parts per billion can be cause for alarm.

Pressure treated lumber production has been all but banned. The phase-out, over a two year period - exempted many industrial uses for CCA and didn't address the 100 billion cubic feet of wood already in use

The industry announced that by the end of 2003 it would voluntarily stop selling CCA-treated wood for most consumer uses.

For decades, millions of consumers have bought and used pressure-treated wood without getting warnings about what was in it or how to avoid exposure to arsenic, a toxic metal that is known to cause cancer in small doses.

March 2001, The Gainesville Sun reported finding - through court records, medical journals and EPA files - more than 40 CCA-related cases around the country.

Many involved carpenters or construction workers. Many involved consumers working on do-it-yourself projects. Many involved exposure to sawdust. Some involved animals. A dozen of the cases were backed by a doctor's testimony or toxicological reports.

In one case, a Seattle man collapsed while building a wooden float for the lake in his back yard. In another, an Indiana man vomited several pints of blood after building picnic tables. In yet another, a New York man swelled up and stopped breathing while building a deck. CCA critics say there are more cases out there. But because of widespread ignorance among consumers, doctors and even carpenters about what's in the wood, only a handful are ever accurately diagnosed, they say. Fewer still are reported to government agencies where they can be tracked.

MPO - Using pressure treated lumber "can be dangerious to one health".

This is true! It works great for moist locations, but care must be taken, mostly with saw dust.
Thanks for the info Smokey!

Hi Smokey, your right I wonder what they are using now. We will probably find out in 20 years or so that it's bad for us too ha! ha!

I think most of the big lumber retailers stopped selling lumber treated with arsenic a few years back when some consumer groups protested their stores. The arsenic also can leach into soil surrounding outdoor projects constructed of that lumber but I am not sure what data has been released on how much of that occurs over the life of the product.

The chemicals in pressure treated lumber can also be absorbed through your bare feet. Children are especially susceptible...

When CCA treated lumber was banned, The governtment gave the industry 2 years to sell off exsisting stock

If one drives around - You may see public playgrounds constructed with CCA treated lumber, public walkways, rest areas, etc. Do I see huge "tear down " projects in the future.

The industry offered the lumber at discount prices to contractors and builders. Many homes have their entire foundations constructed with CCA treated limber.

Anyways - I posted the informatiion, to make aware - to hobbiest - to beaware of the danger CCA treated lumber may cause. Especially if children are around.

Many plywoods and particle boards have or had arsenic in the glues that hold them together. Caution should be used with sawdust.

Many woods give off gases such as formaldehyde.

Carpets sometimes give off fumes from the manufacturing processes.


SO there are many things that caution is needed for and common sense.

Go on living, but be aware of some of the dangers when working with products. ;)

Thanks for the heads up, Smokey. (at least the air where you live is better than the air in some areas, including where I live, we have many ozone action days here)
