Paper Title:
Studies on Activity of Alkaline Phosphatase and Phosphorus Speciation in Sediments from Lake Hongfeng, China
  Abstract

Environmentally significant activity of alkaline phosphatase (APA), phosphorus loading and its species were determined in 14 sediment samples from Lake Hongfeng, one of the key drinking-water sources in Guizhou Province, China. The results of this research indicates that APA presented a high level and notable fluctuations with spatial variations in sediments, ranging from 8.712×10-5 to 25.667×10-5 mol of p-nitrophenol g−1•h-1, and the average value of total phosphorus (TP) in sediments from the lake was 1129.81 mg/kg (dry weight). The content of inorganic phosphorus (IP) was higher than that of organic phosphorus (OP), and the content of the iron/aluminum-bound phosphorus (Fe/Al-P) with phosphorus release risk was also high. In addition, the Pearson’s correlation analysis shows various correlations between APA and Ca-P, Fe/Al-P, OP and IP.
