摘要： As one of the prevailing approaches, the potential ecological risk index (RI) originated from Fldkanson is a diagnostic method for water contamination control intent which considers metal ecological adverse influence, environmental adverse effect and toxicity. In this study, the toxic factor (=30) for Be is calculated depend on Fldkanson's fundamentals. Taking the case of Be polluted river, the environmental risk of Be in the surface sediments is evaluated by ecological risk factor (E-r(i)). This is then compared with the index of geoaccumulation (I-ge(o)) and enrichment factor (EF). Results demonstrate that Be has the resemble contamination grades despite of E-r(i), EF or I-geo indexes is applied demonstrating the appropriateness of the calculated toxic factor. Results of regression analysis further exhibit significant relationships between E-r(i) and I-geo and EF, revealing that E-r(i) is a dependable and reasonable indicator for ecological assessment Be contamination in aquatic environment.
