摘要：

The efficacy of sodium hexametaphosphate, when added to a formalin-Rose Bengal fixative solution, in improving the efficiency of benthic sample sorting by encouraging the disaggregation of silt-clay sediment was investigated. Samples of estuarine mud (Md.vphi. = 6.1) from Damhead Creek, River Medway, were used for the analysis. A significant increase (.simeq. 23%; P < 0.01) in sieving efficiency was found in samples treated with concentrations of 1.24 g/l or more of sodium hexametaphosphate; treatments with higher concentrations than 1.24 g/l did not improve on this performance significantly. The use of 1.24 g/l sodium hexametaphosphate in an initial fixative/preservative solution is recommended as an economic and practical means of improving the efficiency of benthic sample sorting, without deleterious effects on the animal specimens in the sample.
