Nature Water Talks: Water pollution and advanced treatment processes

Could synthetic biology or crispr be used to create bacteria capable of degrading pfas?

Is there a risk of secondary pollution resulting from these degradation techniques？

What are the current consensus views on microplastic transport pathways within living organisms? And does It has any relationship with shapes and sizes？

Hi, this is Manisha Choudhary from UMaine. I have a question for Denise: can presence of PFAS affect setting rate of micro and nanoplastics? Question for Yang Yang: Can microplastics impact degradation efficiency and energy requirements for degradation of PFAS and if yes what do you think in a hood way or negative way? Thanks. Great talks!

To Yang Yang: 1) What is the motivation of using EO and not ER? Apparently, it requires low electrode potential. 2) Are you using metal electrode or sorption assisted electrode for EO? What about mass transfer limitation for metal electrode? 3) Do you know cost differences between ball-milling and incineration for PFAS?

Would you also like to comment on different limits for PFAS worldwide, and its consequences on treatment technologies for their removal?

The SAPEA’s Evidence Review Report on micro- and nanoplastic pollution, published in January 2019 says.“The best available evidence suggests that microplastics and nanoplastics do not pose a widespread risk to humans or the environment, except in small pockets. But that evidence is limited, and the situation could change if pollution continues at the current rate.” Would you agree?

Superfund is difficult to tap into if its a diffuse pollutant with no obvious responsible party
