Summary

Abstract

Plasma from adult smallmouth bass was analyzed for 13 per- and polyfluoroalkyl compounds at 11 sites for a spatial comparison. At four sites a temporal comparison was made over a three year period (2017-2019). At two sites tissue comparisons were made using plasma, whole blood, liver, gonad and muscle. Compounds detected at least once are included in the dataset. For all fish collection site, date of collection, sex, age, length and weight are also documented.
