new research for di 酚S plastics products safety property 同样提出 质疑
密苏里 large 学 一项 new research, for di A plastics products safety property also one-time 提出 质疑. table/sheet in 《 USA 国家科学院院刊》（PNAS） upper material research 论文指出, and di A（BPA） versus ratio, di S（BPS） for table/sheet has same effect/influence. its is BPS by as and BPA for 人体健康 has 害, this category of chemical material 质究竟 has more 危险, currently still in 争议.
di A and di S separation 子式（图自: 维基百科, via New Atlas）
as is types chemical industrial product, di A already in plastics and resin and other products production in to 广泛 运 use. however in 1990 year rear 期, research for BPA safety property 提出 质疑.
year, BPA 一直 诸 more 公共卫生辩论 焦点. a large amount of material research table/sheet 明, BPA 会引发 inner separation function 障碍, 导致代谢疾病, 甚至诱发癌症.
尽 tube/pipe full different machine still for BPA for 人体健康 effect/influence in separation 歧, 但不含 BPA product amount growth, already 经直观 table/sheet 明 公众不愿冒险 想 method.
is substitute/replace BPA, currently has multiple chemical material can formed similar 效果. tube/pipe still has 一 未知 cost, many company 仅仅运 use di combined material （ ratio BPS and BPF）.
has 鉴于此, 仅凭“不含 di A” label 选购商 product, 并不代 table/sheet more tool safety property. ratio 如密苏里 large this new research, comparison BPS and BPA for in small 鼠胎盘 effect/influence.
Cheryl Rosenfeld table/sheet 示, BPS type combined formed chemical material can 穿透母体胎盘, therefore hydrophilic liquid in ring material 质, very easy to in 胎儿.
this type of small type is 我们现 in use BPS in type can can generate function most type, is type and small tool has versus structure.
结果惊人 table/sheet 明, BPA and BPS for material tool has same function, types chemical material 质改变 same 13 基因 table/sheet 达, reduce 胎盘血清素 concentrated degree.
research 人员指出, this chemical material bad 胎盘血清素 generate, reduce 血清素 water can from upper and loss 害胎儿 large in key/critical 时期 发育.
若 in 此期间接触 BPA or related substitute/replace product, can can long defect rear 果. has this research 详情, already table/sheet in day 出版 《PNAS》期刊 upper, 原标题 is:
《Bisphenol A and bisphenol S disruptions of the mouse placenta and potential effects on the placenta–brain axis》
