Session: Current Status of Environmental Research on Water Contaminants:

Mercury toxicity is becoming more prevalent as mercury concentrations in the environment continue to rise – specifically in fish. The levels of mercury retained in fish are distinct to each fish depending on several factors, one being the abundance of air pollution in the environment that the fish was raised. To determine if the mercury concentration in fish is related to environmental factors in a country, fresh farm raised tilapia filets were purchased and different local grocery stores (Waukesha, WI) that were sourced from different countries to compare mercury concentration. The fish were analyzed by DMA-80 Mercury Analyzer. The filets of tilapia had statistically different concentrations of mercury with a concentration range that varies by over a factor of ten.
