Variations of δ~(13)C_(org) and δ~(15)N values, C/N ratios,TOC and TN contents in Chaohu Lake sediments reflect the sources of organic matter in lake sediments,evolution of lake productivity and the eutrophic status in Chaohu Lake during last 100 years.Our results suggest that the sedimentary organic matter was derived mainly from aquatic algae and partly from land matter.However,the input of the pollutants from city and agriculture into the lake could not be neglected.Two stages can be found… CONTINUE READING
