防晒霜最初被用来避免被太阳晒伤,不必符合大多数政府规定。而现在,防晒霜被广泛用于阻止可引发皮肤癌的太阳辐射,皮肤癌是美国最常见的癌症种类。
To test some of the effects of sunscreen, researchers worked with 23 volunteers. They tested four forms of sunscreen byputtingitonmost of the volunteers' bodies four times a day over four days. Then, they did blood tests over seven days to find the levels of certain chemicals absorbed into the volunteers' blood.
在23名志愿者的协助下,研究人员对防晒霜的影响进行了测试。研究人员测试了4款防晒霜,他们让志愿者连续4天每天涂抹4次防晒霜,而且要覆盖身体大部分皮肤。随后,研究人员连续7天对志愿者进行血液测试,以确定志愿者血液中吸收的特定化学物质的含量。
The studylooked forthe chemicals from sunscreen in plasma, the watery part of blood that contains blood cells. It found four chemicals to be well above the level at which FDA guidelines call for further safety testing. They are avobenzone, oxybenzone, octocrylene and in one sunscreen, ecamsule.
研究测量了血浆中防晒霜化学物质的含量,血浆是血液的液体部分,含有血液细胞。研究发现,4种化学物质的含量远高于美国食药监局的规定,含量高到需要展开进一步安全性测试。超标化学成分包括阿伏苯宗、氧苯酮、氰双苯丙烯酸辛酯以及依茨舒。
