According to a recent study, expectant mothers' exposure to high levels of a chemical, called triclosan which is used in toothpastes and soaps, may bring damage to their babies' brains。

英國《每日郵報》11月30日報道，最新一項研究稱，孕婦接觸富含三氯苯氧氯酚的物質(三氯苯氧氯酚常用於製造牙膏以及肥皂)，將會對其腹中胎兒的大腦造成損傷。

In the study, tests on sheep showed triclosan interferes with an enzyme that allows the hormone oestrogen to circulate in the womb. Oestrogen helps to keep open the artery carrying oxygen-rich blood to the foetus. If there is too little, this artery narrows, starving baby's brain of the oxygen it needs to develop properly。

該項研究中，通過對綿羊的測試發現，三氯苯氧氯酚會干擾某種可讓雌激素在子宮內散播的酶發生作用。雌激素可使動脈血管擴張，含氧量高的血液得以流向胎兒。如果雌激素太少，動脈收縮，胎兒大腦會因供氧量不足而發育不全。

Triclosan is a powerful anti-bacterial that was developed nearly 50 years ago. It is now commonly used in everything from toothpastes to washing-up liquid。

據瞭解，三氯苯氧氯酚是有效的除菌劑，早在50年前被人們開發出來。如今被廣泛用於牙膏、洗液等日化用品。

In the UK, the chemical's maximum content allowed in any product is 0.3 percent, and drug giant GlaxoSmithKline has phased out the use of triclosan in its products. But it is still used in brands such as Colgate Total。

目前在英國，三氯苯氧氯酚在產品中的最大含量不得超過0.3%，知名藥品生產商葛蘭素史克已經不再使用三氯苯氧氯酚，而另外一些品牌(比如高露潔)仍用其生產旗下產品。

But a spokesman for the Cosmetics, Toiletry and Perfumery Association said the study in sheep did not prove the same effects would be seen in humans。

但據化妝品香氛聯合會的一位發言人稱，該項以綿羊爲實驗對象的研究並不能證明這些研究結果在人類身上同樣有效。
