Please declare any potential conflicts of interest for this review (or state none if applicable)

None.

None

I do not have any conflict of interest. In 2001, I received funding from 3M Company to conduct research in the area of perfluorochemical survey. Nevertheless, that does not affect my ability to provide objective recommendations and evaluation of reports.

No current conflicts of interest to disclose; a previous advisory role for various Australian government authorities managing PFAS contamination issues could be considered a potential CoI.

None to declare

I see no conflicts of interest, as I have not previously served in litigation or have any financial interest in PFAS either as a group of chemicals or as individual compounds.

None

None.

I am funded by the US federal government (through subcontracts with other academic institutions) and the North Carolina state government to study to immunotoxicity/toxicity of PFAS. I serve as a plaintiff's expert witness in cases involving PFAS. However, it is unlikely that my funding or the payment that I receive for serving as an expert witness will be influenced by the outcome of this activity. I also review scientific manuscripts concerning PFAS toxicity/chemistry/epidemiology and grant proposals that concern PFAS toxicity. It is unlikely that the outcome of this activity will alter my scientific review of these other documents (i.e., manuscripts and grant proposals).
