Description/Abstract:
Report states that elevated Mercury concentrations in fish species from the North Fork of the Holston River observed in the early 1970s has been attributed to a source of Mercury from a chloralkali plant which ceased operation in 1972. Mercury continues to be released from two large waste disposal ponds to the River at the plant site. The report presents results from studies of the emission of Mercury to the environment from abandoned waste ponds and of the distribution of Mercury in water, sediment, and biota of the Holston River--Cherokee Reservoir System in Virginia and eastern Tennessee. The concentrations of Mercury in water and suspended sediments of the North Fork Holston River downstream from the plant were typically 20 times higher than immediately upstream. Concentrations of Mercury in fish species and benthic invertebrates in the North Fork Holston River were lowest above the plant, peaked immediately downstream from the plant, and then decreased further downstream.
