Although the parameters regulating mercury methylation in sediments are fairly well known, conditions controlling the formation and mobilization of methylmercury in aquatic sediments are still poorly understood. In this work the environmental factors governing the distribution and behaviour of total
## Abstract Eight lakes located in the southern half of Saskatchewan were sampled in May and June, 1987, to determine the concentration and spatial distribution of mercury in their surface sediments. Katepwa and Buffalo Pound lakes had maximum total mercury sediment concentrations of 0.158 and 0.10
