Freshwater Inventory and Surveillance of Mercury: Sediment Quality Data

Sediment quality data for 20 lakes across Canada. Parameters include total mercury, methylmercury, sulfate, inorganic and organic carbon, nitrogen, and total recoverable metals. Bottom sediment samples were collected from one to three locations on each lake, following nationally standardized protocols. Sampling period was 2011 to 2016, with some core lakes sampled throughout the period and others sampled one time only.
