Filters containing activated carbon or reverse osmosis membranes have been shown to be effective at removing PFAS from water supplies. All water treatment units require regular maintenance to work properly. Water treatment units that are not properly maintained will lose their effectiveness over time. Other types of common water treatment systems, such as water softeners or iron filtration systems, are not likely to remove PFAS. Boiling water will not remove PFAS. While many homes have whole-house water softening or iron filtration systems, sampling data indicate that those systems do NOT remove PFAS.
US has banned PFAs and related chemicals in November 2016. In November 2023, EPA will have a drinking water maximum contamination level for PFAs. China has not banned PFAs and its related chemicals yet...

饮用水中PFAS浓度最高的城市为自贡(502.9 ng/L)、连云港(332.6 ng/L)、常熟(122.4 ng/L)、成都(119.4 ng/L)、无锡(93.6 ng/L)和杭州(74.1 ng/L)。 黄教授说:“这些城市中PFOS和PFOA的总浓度远超美国环境保护总署2016年发布的非强制执行的健康建议值70ng/L。美国各州设定的最高污染物浓度甚至比联邦指南更为严格,例如佛蒙特州在2019年为五种PFAS(PFOA, PFOS, PFHxS, PFHpA和PFNA,包括单独浓度或组合浓度)设定的最高浓度为20 ng/L.” 作者还发现,超过40%的被研究城市中饮用水污染情况超过了美国加州2019年发布的通知水平,即PFOA 5.1ng/L和PFOS 6.5ng/L.
看来我老公做的研究是对的,他给家里总进水管装了二级活性炭过滤器,
《PFAS 國家主要飲用水法規》提案常見問答
China has not banned PFAs and its related chemicals yet...
谁知道那个滤水器有多安全呢???
瓶本身就是EPA做的,喝瓶水那是自投罗网! 最好喝雨水,天定胜人。
这个是不是需要经常换活性炭芯?
没用
这个管用么?如果活性炭管用的话,水厂出来的不就没有这个问题了么
