An apparent temporal increase in Mn and As in a thin surface layer (ca. 2 cm) of sediments in Lake Biwa, Japan, was
observed by comparing depth profile data from 1977 and 2009. By our estimation, sev...
Possible precursor of perylene in sediments of Lake Biwa elucidated by stable carbon isotope composition
Lake Biwa perylene stable carbon isotopic composition sediment
2017/8/9
We determined the stable carbon isotope compositions (δ13C values) of perylene and compounds coexisting with it to elucidate the precursor of perylene in sediments of Lake Biwa. Although we found a hi...
