根据2000年广西近岸监测数据，应用潜在生态风险指数（RI）和地累积指数（Igeo）对广西近岸重金属污染状况进行评价。结果显示，Igeo低于零，RI低于零，RI也低于95。广西近海重金属潜在生态风险（PER）较低，河口浅海区重金属潜在生态风险较高。 As是广西近海Cu、Pb、Cd、As、Cr、Hg中最主要的污染物。
Based on the monitoring data obtained from Guangxi inshore in 2000, potential ecological risk index (RI) and the geoaccumulation index (Igeo) were applied for assessing the pollution of heavy metals in Guangxi inshore. The results showed that the Igeo were lower than zero, and the RI were lower than zero, and the RI were lower than 95 too. The potential ecological risk (PER) of heavy metals was low in Guangxi Inshore but relatively high in the shallow sea of river estuary. As was the cardinal pollutant among the Cu, Pb, Cd, As, Cr and Hg in Guangxi inshore.
