太可怕了。一天我要用无数次牙线。。 以后改成水牙线好了。
很稳定是什么意思?不容易降解一直在体内?

因为这么稳定 其实理论上来说很难进入人体循环系统造成危害。
为什么稳定就难进入血液循环呢?稳定就不容易被肝降解排出体外了啊?
特氟龙是高分子,稳定不分解,没法被身体吸收
对,应该是加热到300还是400度以上才会产生致癌气体
特富龙有毒吗?吃了会死吗?好怕怕啊。听说有人不当心吞了牙线,肠子肚子全烂光了呢,关键是,连脑子都化啦
水牙线和floss不能相互替代。。
它性质稳定,也就是说不会发生任何化学反应,那么也就不会对身体造成什么危害。 任何东西要有毒性,总得发生一点什么本来不该发生的反应才能造成毒性。这东西不成立。
那是不是可以代谢出去呢?
“代谢”就得靠反应。所以也代谢不了。
化学惰性,不容易发生化学反应被转化为有害物质。所以安全.
大清的时候是全有机的。
现在对化工产品/基因工程等的恐惧是绝大多数是irrational的, 过度夸大的
很多产业就是靠贩卖恐惧焦虑挣钱的
wholefoods就是这样
不代谢,通过胆汁bile从粪便里排出体外
小分子PFAS 是EDC endocrine disruptor chemicals 可能通过扰乱endocrine system 造成毒性 还有就是他们特别稳定+可以在体内富集 persistent 不过毒性离不开剂量 日常不会接触到 痕量没什么事 而且现在基本上长链PFAS 都phase out 了
