Ph affects mercury distribution, not methylation

Mechanisms by which water pH affects mercury distribution are surveyed. Changing values of the pH in natural sediment-water systems did not affect the total amount of methylmercury generated in sediments. Partition of methylmercury between water and sediment did change the total amount; the amount of methylmercury in the water column doubled, decreasing pH by 1.0-2.0 units. This change is enough to explain the observed elevations in mercury levels in fish taken from lakes of low pH. (2 graphs, 7 references, 2 tables)
