ABSTRACT

The project researched the presence of environmental toxicants, human exposure and their health effects on man, plant and animals. Soil and water samples were taken from an industrial dense area at Lagos, Delta and Kwara State. Results from the analysis showed

that the trace metals dissolution into the water and soil respectively were above the permissible dosage of the body thus can pose dangers to the people around the area (ranges from Pb – 0.15u to 0.91u) while the permissible dose varies between 0.05u to 0.51u the soil were not suitable for planting or land animal to live in (3.8 to 3.08 respectively (more acidic) while 5.5 to 7.0 can support plant growth. The microbiological results showed that the presence of E.coli bacteria in all the samples can only serves as a potential dangers to human health.
