The effects of potassium, sodium, calcium,magnesium, and iron on cyanobacterial bloom potentialswere investigated in Daechung Reservoir, Korea. Potassiumshowed the highest correlation with the cyanobacterial cellnumber (r=0.487, P<0.05) and phycocyanin concentration(r=0.499, P<0.05). However, it was not likely that thepotassium had directly affected the bloom formation, becausethe variations of its concentration were not significantly large.In contrast, the Fe concentration fluctuated drastically andexhibited a negative correlation with the cyanobacterial cellnumber (r=-0.388, P<0.1) and phycocyanin concentration(r=- 0.446, P<0.05). Accordingly, the K:Fe atomic ratiowould appear to reflect the extent of cyanobacterial bloommore precisely than K or Fe alone. The K:Fe ratio specificallycorrelated with cyanobacterial percentage, the cyanobacterialcell number and phycocyanin concentration (r=0.840, P<0.001;r=0.416, P<0.05; r=0.522, P<0.01, respectively). With theK:Fe atomic ratio of over 200, the chlorophyll-a concentration,cyanobacterial cell number, and phycocyanin concentrationexceeded 10 mg l- 1, 20,000 cells ml- 1, and 20 pM, respectively,the general criteria of eutrophic water.
