 note = {Series of long-chain anteiso-compounds have been reported in moderately acidic lake sediments as biological markers of acidification (Fukushima et al., 1991a, b, 1993). In this study, we attempted to detect these anteiso-compounds in sediment cores from two acidic lakes : Ohata (pH = 5.2-5.4) in Kirisima and Bessho Reservoir (pH = 3.4-6.7) in Unzen. Core lenghts are 17.5cm and 10cm, respectively. Anteiso-compounds were not identified in the cores from Lake Ohata or Bessho Reservoir. In the Lake Ohata, certain acidophilic bacterial communties which possibly produce the long-chain anteiso-compounds may be absent because this lake is oligotrophic. Although Bessho Reservoir is eutrophic, long-chain anteiso-compounds were also absent from the core. Anteiso-compounds may be found in lakes with biologicaly restricted environments. The composition of n-alkanes, n-alcohols and sterols in sediment cores of Lake Ohata and Bessho Reservoir indicates a contribution of higher plants. In the Bessho Reservoir, low molecular weigth n-alkanes, n-alcohols and 4-methyl-sterols which were probably derived from algae are also common in the core. The small uprise of baseline (UCM) of gaschromatograms of alkanes indicate that oil pollution is a small. Coprostanol was also detected in the sediments of Bessho Reservoir, probalbly polluted with the sewage from the Yunosata and Chijiwa rivers., 長崎大学教育学部自然科学研究報告. vol.53, p.41-55; 1995},
