Samples of surface water were collected from Edagberi Creek from three different stations at intervals of two months for a one-year period. The samples were treated using standard methods and then analyzed for heavy metals concentrations using atomic absorption spectrophotometry (AAS). The metals analyzed were manganese (Mn), mercury (Hg), cadmium (Cd), lead (Pb), copper (Cu), nickel (Ni), iron (Fe), chromium (Cr) and zinc (Zn). The result of the metal concentrations in both stations and months showed the order as Hg < Cd < Pb < Cr < Cu < Zn < Fe < Mn < Ni. The values observed for Fe, Mn and Ni were higher than the WHO and NAFDAC requirement for drinking water, while those of Hg, Cd, Pb, Cr, Cu and Zn were lower than the stipulated values for drinking water by the stated agencies. Contamination factor test carried out on the different heavy metals based on their concentrations and the WHO standard showed that the studied heavy metals were at different level of contamination and pollution classification in the creek. The creek was slightly contaminated-severely polluted with Mn, while that of Hg was within contamination range, Cd and Pb fall within non-contamination to moderate contamination, not contaminated with Cu and Zn, but the creek was moderately polluted with Ni, and non-contaminated to slightly contaminated with Fe and uncontaminated to moderately contaminated with Cr. Pollution index showed that the creek is not polluted with heavy metals. Contamination degree values showed that the creek is at different levels of heavy metals contamination, while modified contamination degree indicated that the creek experienced nil to very low degree of contamination by the metals examined. From the results obtained in the creek, it is advisable that the water should be subjected to treatment before consumption.

Polycyclic aromatic hydrocarbons (PAHs) are possible atmospheric toxins which comprises of fused aromatic rings without considering those that have substituents [7]. They are distinctive pollutants in the environment and are produced constantly from incomplete combustion of waste, petroleum products, coal,

Dry and powdered leaves of Phyllantus fratenus and, Taraxacum officinale were subjected to different solvent extraction using chloroform, methanol and hexane. The extracts were examined for the phytochemical components present in them. It was observed that in Phyllantus fratenus; fats and oil, tannins, saponins, coumarins were present the chloroform extract, alkaloids, glycosides, tannins and coumarins were present in the methanol extracts and in the hexane extract, alkaloids, glycosides, flavonoids and coumarins were present. In Taraxacum officinale; alkaloids, fats and oil, tannins, saponins, flavonoids, terpenoids and steroids were present in chloroform extracts, alkaloids, flavonoids, terpenoids and steroids were present in the methanol extract and in hexane extract, it was only alkaloids and terpenoids that were present. The microbial activity of the various solvent extracts of the different plants showed that the chloroform extracts of both plants were active against S. auereus, and V. cholera, but it was only T. officinale extract that was active against E. coli. In the hexane extracts of both plants, the growth of S. aureues was inhibited in both plants extract, V. cholera growth was only inhibited in P. fratenus extract and E. coli was only inhibited in T. officinale extract. In the methanol extracts of both plants, s. aureus was inhibited in T. officinale extract, V. cholerae was inhibited in both plant extracts and E. coli was only inhibited in T. officinale extract. The observations on the antimicrobial activities of the various plant extracts indicated the reasons of their applications in herbal drug dispensation.
