Abstracts of presentations given in Session 4 of the UCOWR conference.


The North Carolina Division of Water Quality (NCDWQ) has collected data on mercury concentrations in fish tissue from numerous waterbodies since 1990. Reported mercury levels are highly variable; fish tissue concentrations often vary 75-fold or more within individual species across the state, and 10-fold to 100-fold among samples within and between adjacent counties. We discuss the construction and preliminary analysis of a comprehensive statewide database combining NCDWQ fish tissue mercury concentrations with all other available and relevant biotic and abiotic environmental variables.
