Abstract

Based on the chemical mass balance (CMB) model, the heavy metals deposited in the bottom sediment of Hongfeng Lake were apportioned to the tributaries and point sources. The results showed that contribution proportion of tributaries serving as non-point sources was much higher than that of point sources. The main sources contributing to the heavy metals in sediments of Hongfeng Lake were Houliu River (about 39% in upstream source combination and 60% in estuary source combination) and Maiweng River (about 45% in upstream source combination and 29% in estuary source combination). For the heavy metals in sediment identified as heavily enriched by man-made effluents, the source apportionment results showed that H 9 was from the estuary area of Maiweng River; T i, and A s, pollutants were mainly Maiweng River and Houliu River. The concentration of C d well reflected the surrounding land uses because its limited transportation distance. The source apportionment analyses for Hongfeng Lake were helpful for water protection and pollution control management in this region.
