Abstract

The study assessed human health risk and accumulation of heavy metals (Cd, Cu, Pb, Ni, Cr and Zn) in periwinkles (Tympanotonus fuscatus) obtained from the Niger Delta region of Nigeria. Samples were collected for six months on a monthly basis. The samples were digested according to the method described by Association of official analytical chemists and analyzed using atomic absorption spectrophotometer (AAS). Temporal variations in metal concentrations were observed with values (mgkg-1) ranging as follows Pb (2.34-6.7), Ni (0.55-2.28), Zn (0.55-11.66), Cr (0.74-3.65), Cu (1.15-3.91) and Cd (0.22-1.06). Variation in metal concentration was significantly different (p
