Polycarbonate plastic is used for a reason: It's useful. Hard, shatterproof, lightweight and clear, it's in a huge range of products from water bottles and food storage containers, to lenses in eyeglasses and car headlights, CDs and DVDs, and even bulletproof glass. "Whether you realize it or not, you use it in your life every day," says Steven Hentges, head of the polycarbonate group at the industry lobby organization American Chemistry Council. There are, of course, alternatives to polycarbonates, like glass and other plastics. And for the growing number of consumers opposed to bisphenol A, there...
...What's Toxic in Toyland" [Dec. 11] included misleading information about substances that make plastic toys and other children's products soft (phthalates) and shatterproof (bisphenol A., or BPA). Phthalates have been used in consumer products for more than 50 years. During that time, no reliable research has ever found that phthalates cause negative health effects in humans. The Consumer Product Safety Commission in 2003 completed a four-year review of the main phthalate used in vinyl toys (called DINP) and found "no demonstrated health risk" and "no justification" for banning it, as the City of San Francisco has done...
...controversy centers on a family of chemicals called phthalates (pronounced "thalates"), which are used to soften vinyl, and on bisphenol A (BPA), a substance used to make clear and shatterproof plastic. Most are known to be so-called endocrine disrupters, capable of interfering with the hormones that regulate masculinity and femininity. Several hundred animal studies have linked phthalates to prostate and breast cancers, abnormal genitals, early puberty onset and obesity. More recently, they've been shown to affect humans as well. In a paper published last year in the journal Environmental Health Perspectives, scientists from the Centers for Disease Control...
...volume centers instead on the Society for Germinal Choice, nicknamed the Nobel Prize Sperm Bank by reporters, which eccentric millionaire Robert Graham founded in 1980 and bankrolled thanks to his patent on shatterproof eyeglasses...
...He’s an enthralling character. He made a profound improvement in American life by inventing shatterproof lenses—a genuinely huge advance. And he was motivated by essentially noble, and relatively harmless, goals. But he suffered from the problem of hyper-rationalists everywhere—the belief that the world would work perfectly if only smart people like me were allowed to control it and keep the morons in line...
