对琵琶湖溶解钒浓度的月度调查清楚地揭示了迄今未报道的季节性变化。在湖泊表层，溶解钒浓度在5月份开始增加，夏末达到最大值，秋季下降。相比之下，在底层（70米深），浓度全年几乎保持不变。富营养化湖盆南部溶解态钒浓度的增加幅度大于中营养化北方湖盆。
Monthly survey of dissolved vanadium concentration in Lake Biwa has clearly revealed a seasonal variation hitherto unreported. In the surface layer of the lake, dissolved vanadium concentration started to increase in May, reached a maximum value in late summer, and decreased in fall. By contrast, in the bottom layer (70 m depth), the concentration remained almost constant throughout the year. The increase of dissolved vanadium concentration in the eutrophicated southern basin of the lake was greater than the one in the mesotrophic northern basin.
