Abstract
The concentrations of selected heavy metals (Cd, Cr, Cu, Fe, Mn,
Pb, and Zn) in three brands of sachet water sold within Lokoja, Nigeria, were
determined using Atomic Absorption Spectroscopy (AAS). The results revealed
that the sachet water samples contained varying levels of these heavy metals.
All the metals were present in all the tested brands at concentrations below
the WHO and US EPA permissible limits for drinking water. For Cd, the estimated
daily intake (EDI), was calculated to be slightly higher than the RfD or
reference limit, making it a source of health concern. All the other metals had
EDIs that are less than their RfDs. Overall, the sachet water brands were found
safe for drinking.
