Target hazard quotient evaluation of selected trace elements in highly consumed crustacean species in Lagos, Nigeria

Crustaceans are known for their trace element bioaccumulation abilities. Muscle tissues of lagoon crab, marine pink shrimp and mantis marketed consumption in Nigeria were analyzed Mn, Fe, Cu, Zn, Hg Cr levels using standard methods. mg kg-1 Mn (0.03±0.00 crab), Fe (0.072±0.01 shrimp), Cu (0.344±0.01 crab) Zn (0.073±0.00 shrimp) significantly different (p<0.05) from corresponding values other examined crustaceans. The mean not across samples. estimated daily intake (mg person-1day-1) revealed that (0.000001) crab contributed the lowest while (0.000226) highest intake. Total hazard quotient (THQ) elements followed descending order > Cr. Lagoon showed total index among organisms with 44.80 %, least was observed 13.30 %. It is concluded that, as far human health concerned, elemental muscle pose no danger (THQ < 1).
