O'Donnell is now the director of sales for a technology company. He recently paid $110 for a 7-foot artificial tree. "I guess if we miss the pine smell, we can buy some candles," he said. To draw people to their sides, both tree associations make claims about the safety of the other products, with topics including allergies and lead dangers. The NCTA points to the artificial trees that end up in the landfill, while real trees can be recycled, for example. The ACTA published a study on its website this month that concluded either kind of tree has a negligible impact on the environment. Safety-testing company Underwriters Laboratories Inc. said fire is the biggest threat, not the possibility that artificial trees contain lead. The company notes that natural and some artificial trees can burn up in as little as a minute. "That's why we test for fire," said John Drengenberg, UL's director of consumer safety. "It has not been for lead." In 2004, researchers at the University of North Carolina at Asheville concluded that an average artificial tree doesn't present a significant risk for exposure to lead. They did warn, however, that a significant health risk to young children is possible in worst-case scenarios. And they noted that some tree lights also contain lead. Some also claim one tree or the other is worse for causing sneezing or sniffles, but allergists are divided on which is worse. Dr. Neeta Ogden, an allergist in Englewood, N.J., blames artificial for the worst problems. "The main reason is that people store them in their homes in the basement and attic, and those are places where they're going to attract dust and mold," Ogden said. But Dr. Neil Kao, an allergist in Greenville, S.C., recommends artificial trees to his patients. Both can accumulate dust, but Kao also counts the tree aroma and the water that sits in the stand as negatives for the natural tree. For patients with severe asthma and sinus problems, he recommends a poster of a tree. "It's not very touchy-feely, but it serves the purpose." ___ Online:
