Spatial distribution of phosphorus fractions in the sediments of fVEeiiiang Bay, Taihu Lake, China

摘要

The amounts of phosphorus fractions in the sediments of Meiliang Bay were examined using the SMT sequential method. Results indicated that the TP concentration in surface sediment averaged 594.90 mg/kg (284.06-945.14 mg/kg) and mainly composed of IP (60%-80%). Pollution was more serious near the four inflow rivers. Phosphorus fractions in the core sediment showed a decreasing trend. Correlation analyses showed that NaOH-P was the main factor controlling TP.
