Organisms can draw power by feeding on organic carbon compounds and then oxidizing the reduced carbon back to carbon dioxide.

生物体可以通过以有机碳化合物为食，然后将还原的碳氧化回二氧化碳来获取能量。

In a study published in 2020, Dr. Knappe and his co-authors found that, on average, pitcher and refrigerator filters that use activated carbon reduced PFAS levels by about 50 percent.

在 2020 年发表的一项研究中，Knappe 博士和他的合著者发现，使用活性炭的水壶和冰箱过滤器平均可将 PFAS 含量降低约 50%。
