  • Abstract:

The impairment of coastal waters as a result of microbial pollution have had a tremendous impact on living
organisms and human health, and is a major challenge confronting the water industry and regulatory
authorities.Thus, the current study was carried out between May-July 2014, to assess the physico-chemical
parameters and microbial load in water, sediments and tissue of Nematopalaemon hastatus and Farfantepenaeus
notialisfrom two coastal water bodies of Ondo State (Ayetoro and Bijimi). The microbial load parameters that were
analyzed are Total Heterotrophic Bacteria Count (THBC), Total Coliform Count (TCC), Total Shigella and
Salmonella Count (TSSC), Total Vibrio Count (TVC), Total Fungal Count (TFC), and Escherichia Coli Count
(ECC). The results of the analyses of the water samples showed that temperature had the highest value of
31.00±0.00oC in Bijimi, with the lowest value of 27.67±0.58 oC in Ayetoro. Turbidity range from 0.01±0.01 to
0.04±0.01 NTU,while conductivity had the least mean value of 1.77±0.06 μS/cm in Ayetoro and the highest mean
value of 9.30±0.30μS/cm in Bijimi. pH range between 4.77±0.06 to 6.04±0.01. The result revealed that all the
physico-chemical parameters of water determined except turbidity and conductivity showed no significant
difference across the stations at P<0.05. The total count of heterotrophic bacteria was found to be highest in water,
sediment and organismsat 128–650, 66-210 and 110-216 respectively, whileV. cholerae was not detected in water
and organisms, but detected in sediments. The level of natural, human and anthropogenic microbial contamination
into the coastal waters of Ondo state amongst the two stations follows the order sediment>water>organisms. This
present study therefore reveals the risk associated with the health status of the Coastal water of Ondo State which
may further deteriorates and become detrimental to the coastal community.
