NFLD lake sediment compliation of ~17000 sites.  A 1 gram sample was digested in 6 ml of a 4M HNO3, 1M HCl mixture in a water bath at 90oC for 2 hours. For typical organic lake sediment this digestions yields values that are >80% of total content.  The element was determined by AAS but there may have been variations in detection limit and technique over the years.
