(2015·呼和浩特第一次调研)Many people may be surprised by the number of chemicals that they are exposed to through everyday household products.
In a study 25 women had their homes and bodies tested for 89 environmental pollutants—including pesticides(杀虫剂) and chemicals found in plastics and cleaning products. On average 20 chemicals were found on their bodies or in their homes.
Much is unknown about the possible health effects of chemicals in everyday household products. But certain chemicals—like phthalates (邻苯二甲酸盐) found in plastics—have been linked to potential health risks, including higher risks of certain cancers, though the evidence mainly comes from research on lab animals. Other household chemicals are known to harm the skin, eyes and airways—and may worsen asthma(哮喘). Many more chemicals found remain untested.
Chemicals likely come from a range of sources, so it is not always clear how to reduce people’s exposure, according to Dr Rebecca Altman, the lead researcher on the new study.
