| Distribution of microorganisms (heterotrophic bacteria, total fungi, proteolytic bacteria) and environmental parameters were investigated at three sites (site I, upper side of Naktong River Estuary Barrage; site II, III, under sides of Naktong River Estuary Barrage). Ammonia concentration $(435{pm}320;{mu}g;{NH_4}^+-N/l)$ in Site I was higher than in Site II$(198{pm}96;{mu}g;NH_4^+-N/l)$ and Site III$(208{pm}116;{mu}g;{NH_4}^+-N/l)$, and it correlated negatively with rainfall (r=-0.52, p<0.05). Also nirate concentration ranged from 255 to $801;{mu}g;NO_3^--N/l$, and phosphate concentration ranged from 16 to $115{mu}g;{PO_4}^{3-}-P/l$, and chlorophyll a concentration ranged from 6.9 to $153;mg/m^3$. The numbers of bacteria and fungi in site I were also higher than site II and III. The number of microorganisms correlated positively with water temperature (r=0.46, p<0.1), the concentration of inorganic nutrients, and precipitation (r=0.52, p<0.05). These results suggest that nutrient materials have increased continuously and polluted compounds have loaded in steady in Naktong Estuary after the construction of estuary barrage. |
