Abstract:In many basins across the United
States, oil and gas (O&G)
wastewater high in alkaline earth metals (such as Ba, Sr, and Ca)
and radioactivity is discharged to surface waters. Freshwater mussels
have experienced high mortality rates downstream of O&G discharges
despite significant dilution. 87Sr/86Sr and
Sr/Ca measured in mussel soft tissue could prove to be an inexpensive,
efficient biomonitoring tool if tissue concentrations show O&G
produced water signatures similar to those of shells. O&G-derived 226Ra/228… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
