This study is intended to support the development and implementation of risk management strategies that will ensure the safety of the Lagos Lagoon through a scientific basis for the control of POPs constituents present in the Lagoon.

Water samples were collected at each sampling station at a depth of 2m below the water surface with a pre-cleaned 1L glass bottles. Surface sediment samples were collected with a stainless steel eckman bottom sampler.
