摘要:... The level of contamination with the analyzed metals was determined according to the following indices: geo-accumulation index ( I geo), enrichment factor (EF), pollution index (PI), integrated pollution index (IPI) and potential ecological risk index (RI). The...

摘要:... Geoaccumulation index and Hakanson potential ecological index were used to calculate the ecological risk of sediment environment in this paper. The I geo results indicated that the sediments were moderately contaminated by Hg and Pb. The potential ecological risk...

摘要:... This study determined the degree of contamination of 13 metals (Al, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Cd, Hg and Pb) in Kafue River sediment and the associated ecological risks at six sites in three different seasons. The level of contamination for most metals showed sig...

摘要:Abstract(#br)Modified potential ecological risk index (MRI) was proposed based on the potential ecological risk index (RI) and risk assessment code (RAC) by modifying an index. The modified index was relevant to the chemical speciation of heavy metals. Xiawan Port, a typical regi...
