Bioaccumulation of heavy metals and parasitic fauna in Synodontis clarias (Linnaeus, 1758) and Chrysichthys nigrodigitatus (Lacepede, 1803) from Lekki Lagoon, Lagos, Nigeria

Conclusions The findings of the concentrations of the trace elements in the aquatic habitat as well as the sediment were below the permissible limit of Federal Ministry of Environment. These findings confirmed that the aquatic habitat was adequate for fishing activity and that the consumption of fish species therein are safe. However, it should be noted that there was bioaccumulation of trace elements in the fish tissues which should not pose any danger to man. Therefore, a regular monitoring of the levels of trace elements in the water body as well as in the fauna should be regularly undertaken.
