Arsenic Threat: Pressure Treated Wood
Jay Feldman, the executive director of the group "Beyond Pesticides" based in Washington, D.C., calls this chemical a hidden danger. Arsenic is a known human carcinogen; exposure to it could cause cancer. Mr. Feldman is calling on the Environmental Protection Agency for an immediate ban on toxic wood preservatives like CCA. "People unknowingly are lounging on their decks. Their kids are playing on playground equipment. They are engaged in building projects. All the while, not aware that there's a hazard, a very severe hazard, lurking," Mr. Feldman told the I-Team.
But a vice president of Universal Forest Products of Grand Rapids, Scott Conklin, says CCA-treated wood is safe. "People have tried to be alarmists," he told us. "They've tried to banter around the name arsenic, to frankly to scare people." Mr. Conklin charges that people who raise concerns about CCA are "not grounded in science."
First of all, we tested soil and wood at two West Michigan playgrounds for levels of arsenic, the known carcinogen. We sent soil samples and wipe samples from the wood structures to the two labs, then sat down with a toxicologist.
The soil sample at Kids Palace of Coloma contained as much as 169 parts per million of arsenic. The soil sample from Randall Park in Lawrence had as much as 177 parts per million of arsenic.
Michigan's Department of Environmental Quality says that its standard of risk for residential cleanup is 7.6 parts per million. "We do know that arsenic is toxic. We do know that arsenic is in this wood. We do know that arsenic is released from this wood. We should do what we can to prevent our kids from being exposed to that," said Dr. Bernard H. Eisenga, the medical director of the Regional Poison Center.
Dr. Eisenga was even more disturbed at the lab tests on the wipe samples. "That's a very large amount of arsenic - especially the 2,900. That's 2.9 milligrams of arsenic that you're removing in a wipe sample."The physician believes exposure to this level of arsenic could create a greater risk of cancer for a lifetime. He's not alone.
In March, 2003, government scientists with the U.S. Consumer Product Safety Commission reported that children who play on CCA-treated playground equipment are at a higher lifetime risk of developing lung and bladder cancer.
The predictions of greater health risks come just as dozens of lawsuits have been filed over various alleged medical problems. One is over what happened to a woman named Terry Sleep, who lives near Charlotte. After a tiny sliver of the wood became imbedded in her leg (from scraping against her deck) she developed a severe case of poisoning. Four surgeries later, she says it was a terrible experience. "It's just been an awful, awful experience," she says. "It really has."
Government experts are still testing sealants to try to determine what can work to stop the arsenic from coming out of the wood. In the meantime, they urge immediate hand-washing if you or children touch CCA-treated wood. "The idea is that arsenic is poison," says Jim Hahn, of Carpenters Local 525. "And you treat it like a poison."
