"We don't operate to different standards in different parts of the globe, regardless of differing environmental standards," said John Frey, manager of corporate environmental strategies at Palo Alto-based Hewlett-Packard.
But many U.S. and foreign companies do.
Some toys, nail polishes and other beauty products are made with plastic softeners and solvents called phthalates that the EU has banned as reproductive toxins. Several of U.S. agriculture's most popular herbicides and insecticides, including atrazine, endosulfan and aldicarb, are illegal or restricted to emergency uses in other countries. And a few electronic items, including Palm's Treo 650 smart phone and Apple's iSight camera, were pulled off shelves in Europe this summer because of lead components but are still sold here.
Industry groups say their products have undergone rigorous reviews in the United States and are not only legal here but safe. They say some governments, particularly the EU, have overreacted and banned chemicals with little or no evidence of a human health threat.
"Consumers can remain confident about using their cosmetics given their oversight by the Food and Drug Administration, the extensive research on their safety and long history of safe use," the Cosmetic, Toiletry and Fragrance Assn. said.
The EPA hasn't eliminated any industrial compounds since it sought unsuccessfully to ban asbestos 18 years ago. Unlike EU policies, U.S. law requires the EPA to prove a toxic substance "presents an unreasonable risk of injury to health or the environment," consider the costs of restricting its use and choose "the least burdensome" approach to regulate industry.
"The dumping problem is concentrated in a few product sectors. But these sectors happen to be really ubiquitous in the everyday lives of Americans. Chemical risks are being spread all over the country in ways that are invisible to consumers," said Alastair Iles, an international chemical policy expert who was a research fellow at UC Berkeley and still works with faculty there on consumer issues.
Last year alone, China exported to the United States more than half a billion dollars' worth of hardwood plywood -- enough to build cabinets for 2 million kitchens, a sixfold increase since 2002. Though China sends low-formaldehyde timber to Japan and Europe, Americans are getting wood that emits substantially higher levels of the chemical.
