Appendix F
Studies on Behavioral and Physiological Endpoints on Select Organic UV Filters
The studies found in the appendix include in vivo and in vitro behavioral and physiological (genomic, biochemical/biomarker, and cell-based) assay systems for aquatic organisms. Findings from these studies are not typically used in ecological risk assessment without links to population-relevant endpoints, but may be informative to understanding mode(s) of action. These studies are summarized in Chapter 6 in the section Biomarkers, Biochemistry, and Physiology Studies Informing Mode(s) of Action. Inorganic UV filters are not included in this appendix because a representative (though not comprehensive) compilation can be found in the U.S. Environmental Protection Agency’s ECOTOX database and thus was not comprehensively compiled by the committee.
