摘要：
The levels of Cu, Fe and Zn in water, sediment and Cynothrissa mento, a commercially important fish species, were investigated from April 2007 to March 2008 at three sites in Ologe Lagoon. Metal levels in the water column and C. mento were lower than the FAO/WHO drinking water and food safety limits. In most cases, metal concentrations were highest during the dry season and lowest in the wet season. Metal concentrations in sediment and C. mento varied significantly among the sampling stations, but in the water column only the levels of Fe and Zn differed significantly between stations. Concentrations of metals in C. mento were significantly affected by wet and dry seasons. The metal concentrations in Ologe Lagoon were lower than the values reported in some Nigerian water bodies. While the Ologe Lagoon system contains the heavy metals studied, their levels in the water, sediment and fish are still within acceptable limits.
