this study investigated the impact of internal nitrogen and phosphorus loading on water qualityof lake chaohu, china. results showed that the overall mean concentration of tn and tp in lake water was1.09±0.84 and 0.15±0.84 (sd) mg/l, respectively, indicating lake chaohu was highly eutrophic during thestudy period. mean benthic flux of nh4 +, no3 -, and po4 3- were 3.56±1.52 mg n/m2/d, -0.14±0.4...
