Abstract
Several methods are in use to measure total phosphorus in lake sediments making cross-study comparisons tenuous, and may lead to potential errors in calculating other phosphorus fractions. Four methods in common use in the limnological literature were compared using sediments spanning a range of organic content from 2 to 35% C. No significant differences were found in within-lake comparisons, although a method using persulfate oxidation was highly variable, and this variability was correlated with organic content suggesting inconsistent oxidation. The other methods (combustion, acid digestion with HClO4, H2SO4 + H2O2) gave uniformly small variances.
