Distribution and turnover of phosphorus and BHC in a grassland were analysed in Oita Prefecture and Kumamoto Prefecture from March to September in 1983. Large differences in bioconcentration between phosphorus and BHC in the organisms of a grassland ecosystem were observed. The content of TP (total phosphorus) in organisms increased with the elevation of the ecological position of the food chain, whereas the opposite phenomenon was observed in BHC residues whose concentration was high in soil (H-layer in Senomoto Table Land; a meadow, Kumamoto Pref.) and litter (in Bogazuru, Oita Pref.), and low in plants, insects and mammals. The content of BHC residues increased with plant growth and after dry grass in the grassland had been burned, the content of residues in soil increased.
