| 用來製造聚碳酸酯（PC）水壺、環氧樹脂和熱感應紙收據等多種用品的雙酚A（BPA），被發現有害人體生殖系統後，逐漸被雙酚S（BPS）取代，不過美國加州大學洛杉磯分校學者發現，BPS其實跟BPA一樣危險，而且能對女性卵子造成傷害的劑量比BPA還低。 由於來自消費者的壓力越來越高，製造商紛紛推出標榜「BPA-free」的產品，以其他物質取代BPA。 不過，在尋找有毒物質替代料時，製造商傾向採用具相似物理特性的物質來替代，但我們並不清楚這些替代物質的安全性。因此，研究人員開始研究BPS是否對生殖系統有和BPA有類似的影響。 「這份研究清楚顯示，消費性產品製造商在替換有毒化學物質時，是採取頭痛醫頭、腳痛醫腳的態度。急需要一套安全評估辦法，在替換物質和化學品混合物上架前把關。不過好消息是，目前已有許多政府計畫和學術實驗室正在朝這個方向努力。」UCLA Fielding公衛學院環境健康科學助理教授亞拉德（Patrick Allard）說。 News Date: 2016/8/23 Source: Environmental Information Center Subject: Environmental Technology Used to make polycarbonate (PC) kettle, epoxy resin and heat sensitive paper receipts and other items of bisphenol A (BPA), has been found to be harmful to human reproductive system, gradually replaced by bisphenol S (BPS), but the United States UCLA researchers found that, BPS actually as dangerous with BPA, and can cause damage to the female egg dose lower than BPA. Due to increasing pressure from consumers, manufacturers have introduced advertised "BPA-free" products to replace other substances BPA. However, in looking for alternative materials of toxic substances, the manufacturers tend to use substances with similar physical characteristics to replace, but we do not know the safety of these alternative substances. Therefore, the researchers began to study whether the BPS on the reproductive system and BPA has a similar effect. "This study clearly shows that consumer goods manufacturers in the replacement of toxic chemicals, is to take stop-gap measure of attitude. To a much-needed safety assessment approach in alternative substances and chemical products added to the mixture before checks but the good news is, there are many government and academic labs are plans to move in this direction. "UCLA Fielding School of Public health assistant professor of environmental health Sciences Yala De (Patrick Allard) said.
