; and (B) to submit reports describing the results of the studies in accordance with this subsection. (2) Phase I study and report on human exposure estimation (A) In general The phase I study under paragraph (1) shall, at a minimum— (i) consider lifecycle information on the manufacture, use, and disposal of products containing perfluoroalkyl and polyfluoroalkyl substances to identify potential human exposure sources and pathways; (ii) evaluate— (I) the fate and transport of perfluoroalkyl and polyfluoroalkyl substances; and (II) the breakdown products of perfluoroalkyl and polyfluoroalkyl substances, as related to human exposure; (iii) if feasible, estimate human exposure to individual perfluoroalkyl and polyfluoroalkyl substances or perfluoroalkyl and polyfluoroalkyl substances collectively to determine relative source contributions for various exposure pathways (such as air, water, soil, or food); (iv) determine which perfluoroalkyl and polyfluoroalkyl substances are most likely to contribute to human exposure; and (v) identify research that is needed to advance exposure estimations to individual perfluoroalkyl and polyfluoroalkyl substances or perfluoroalkyl and polyfluoroalkyl substances collectively. (B) Report Not later than 1 year after the date on which the agreement described in paragraph (1) is finalized, the National Academies shall— (i) submit to Congress a report containing the findings and recommendations of the study described in subparagraph (A); and (ii) make the report under clause (i) available on a publicly accessible website. (3) Phase II study and report on PFAS toxicity and hazard estimation (A) In general The phase II study under paragraph (1) shall, at a minimum— (i) (I) review animal and human toxicity information on the perfluoroalkyl and polyfluoroalkyl substances most likely to contribute to human exposure, as identified in the phase I report under paragraph (2)(B)(i)
