Abstract:

Fixed-point observation method was used to observe the four butterfly lakes of Nanji Poyang Lake for one year in order to reveal the annual changes of aquatic plants.Atomic Absorption Spectrophotometry (AAS) and Inductively Coupled Plasma Mass Spectrometry (ICP-MS) were used to determinate the contents of heavy metals (Cu,Zn and Pb) in water,sediment and aquatic plants.The results showed that there were 12 species which belong to 11 genera of 8 families in four butterfly lakes.Nymphoides peltatum, Hydrilla verticillata, Najas marina and Vallisneria natans were their dominant plants.The water depth and transparency increased first and then decreased in one year.The maximum water depth and transparency were 269.4 cm and 170 cm respectively in July.Aquatic plants biomass was increasing from January to September.11 250.0 g/m² was the maximum biomass.The average height and density of dominant Hydrilla verticillata was 104.7—124.5 cm and 875—2 200 root/m² respectively in September.The content of Cu,Zn and Pb in water of butterfly lakes met with the environmental quality standard for grade I surface water,but the content of Zn and Pb were higher than the water quality standard for fisheries.At the same time,the contents of the analyzed heavy metals in sediment of butterfly lakes were all higher than their background values,indicating an accumulation trend.The order of increased speed in sediment was Cu＞Zn＞Pb.The results further revealed that the eco-toxicological effect of Cu,Zn and Pb had caused obvious hazard on bentonic organisms.
