"They were originally used in small quantities to prevent sunburn on vacation," Andrews said. "Now they recommend applying these every day, applying them to large parts of your body. And the FDA began raising concerns."
安德鲁斯说:“原本人们只是在度假的时候少量使用防晒霜,以防止被晒伤。但现在商家建议人们每天都使用防晒霜,并在身体上大面积地涂抹。因此食品和药物管理局开始提醒人们注意。”
The new FDA study enrolled 24 healthy volunteers who were randomly assigned to a spray or lotion sunscreen that contained avobenzone, oxybenzone or octocrylene as ingredients or a crème sunscreen that contained the chemical ecamsule.
食品和药物管理局的这项新研究招募了24名健康的志愿者,随机让他们使用含有阿伏苯宗、氧苯酮或奥克立林的防晒喷雾或防晒乳液,或使用含有依茨舒的防晒霜。
The volunteers were asked to put their assigned sunscreen on 75% of their bodies four times each day for four days. Thirty blood samples were taken from each volunteer over seven days.
志愿者被要求将指定的防晒霜涂在身体四分之三的皮肤上,每天涂四次,连续涂四天。在七天时间内,研究人员从每名志愿者身上抽取30份血样。
Of the six people using the ecamsule cream, five had levels of the chemical in their blood considered statistically significant by the end of day one. For the other three chemicals, especially oxybenzone, all of the volunteers showed significant levels after the first day.
