问题     As part of an ongoing campaign against polyvinyl chloride(聚氯乙烯), a Virginia-based environmental advocacy group today called on manufacturers and retailers to phase out its use in shower curtains. The Center for Health, Environment and Justice(CHEJ), released the results of a small study indicating that PVC(聚氯乙烯)-containing shower curtains are capable of emitting scores of potentially harmful materials, into people’s bathrooms. A previous study, conducted by Environmental Protection Agency researchers, also found that plastic shower curtains can emit toxic compounds into the air.
    There’s still debate among scientists about just how serious the health effects are especially at low doses. However, CHEJ urges consumers to avoid using PVC shower curtains, as well as many other PVC products.
    For people who are concerned about their shower curtains, there are alternatives. IKEA phased out PVC shower curtains 11 years ago, switching to ethylene vinyl acetate(乙烯醋酸共聚物). The company has said that 88 percent of its shower curtains would be PVC free by spring of 2008.
    Manufacturers are not required to label shower curtains, but some do list" PVC "or" vinyl" on the packaging. Numerous online retailers, sell shower curtains—primarily cotton or hemp—that are free of PVC. However, mildew(发霉)can be a problem with cotton and hemp products.
What did the study released by the Center for Health, Environment and Justice show?
选项 A、That PVC stands for polyvinyl chloride.
B、Manufacturers are not required to label shower curtains.
C、That most shower curtains sold at IKEA are made from PVC.
D、That PVC shower curtains may release potentially harmful materials.
答案D
解析 这篇文章是关于浴室的浴帘含有聚氯乙烯的问题。第一段指出，健康环境及正义中心发布了一个研究报告，证实含有聚氯乙烯的浴帘可放射大量的有害物质。选项D是正确的。
