Impact of Heavy Metals on Growth and Mortality in a Freshwater Bivalve (Epioblasma brevidens)
By Samantha Romines 2020
Dr. Michelle Hurley
Dr. Dinah Deford
In 2008, The clinch was subject to a coal ash spill dumping 4.1 million m3 of ash into the aquatic ecosystem.
Populations of freshwater mussels has fallen over 80% in the past 10 years.
Cumberland Combshell is an endangered freshwater mussel in the Clinch River.
Heavy metals effect freshwater mussels physiologically.
Lead and Mercury can leave deposits in the gills and mantel. Cadmium can be found in the digestive gland and kidneys.
Determine if the sediments of the Clinch River have contamination levels high enough to effect the Cumberland Combshell.
Explore the survivability of Cumberland Combshell mussels with in high exposure rate.
Explore the downstream effects of contamination sediments on survivability of the Cumberland Combshell.
In lab testing with husbandry acquired juveniles (240).
Sediments will be collected from four locations on the Clinch river. Control will be above the spill site. Experiment 1 will be the highest exposure with in .5 Km of spill site. Experiment 2 will be .5 Km downstream of spill site. Experiment 3 will be 1 Km downstream of spill site.
Each group will be 60 individuals and be exposed to correlated locations. Dry weight, biomass and glycogen analysis bi weekly with 6 individuals chosen at random.
The group closest to the high exposure location will have lower bio mass and lower glycogen analysis
Down stream location will also have effects, it is possible for them to have better over all rates compared to the exposure location
