“…The levels of the physicochemical parameters in the water samples were carried out to ensure that the water samples were not polluted and that their quality meet the recommended standards of water quality for drinking and can support life. These parameters were determined to rule out the possibility that some of them could be present in the water from leakages [17]. The obtained values of the parameters were all below the World Health Organization recommended values except the pH and temperature of all the water that were higher than the recommended value of 6.5 -8.5 and 25 O C respectively.…”

Introduction: Certain kitchen utensils used for food preparation can present significant risk because they are manufactured with materials such as aluminum, stainless steel and enamel that can be hazardous or contaminate food when heated. Aim: The aim of this study was to determine the microbial and heavy metals found in leachates from some cooking utensils subjected to heating. Methodology: A total of four aluminum and stainless steel cooking pots were used and seven hundred and fifty (750) millilitres of tap water was boiled for 15 minutes to 30 minutes in each of the pots at boiling point of 100°C. The analyses of the water samples for bacteria were carried out using the conventional standard procedures of isolating and identifying bacteria. The physicochemical parameters were quantified with the APHA method whereas the Atomic Absorption Spectrophotometer (AAS) was used for the determination of heavy metals. Results: The results showed that Pseudomonas spp and Staphylococcus spp were isolated from some of the water samples that were not boiled while the boiled water showed no bacteria growth. The physicochemical parameters of the water samples before boiling were pH 5.36 to 7.41, temperature 30.7°C to 31.0°C, turbidity 0.04 to 1.41NTU, total dissolve solids 50.0 to 114.9 mg/l and others, while the presence of heavy metals such as Lead (Pb), Zinc (Zn), Iron (Fe), Cadmium (Cd) and Chromium (Cr) were detected in leachates from the pots subjected to heating. The values obtained were higher in leachates from pots that were heated for longer period. The oldest pot of thirty (30) years had a value of 0.0175±0.0007 mg/l to 0.0275±0.0021 mg/l for Zn while the value for Cd was 0.1110±0.0014 to 0.1245±0.0007 mg/l and the values for the newest pot was 0.0505±0.0021 to 0.0775±0.0035 mg/l for Pb and 0.0455±0.0248 mg/l to 0.0515±0.0191 mg/l for Cr. Conclusion: Cadmium values in all the pots exceeded the control and World Health Organization (WHO) recommended values. It may be concluded that heavy metals leached out into water and food from some pots when heated for longer periods and this may become one source of exposure of heavy metals into the human body that may bioaccumulate to create health problems.

“…It is one of the most important, valuable and renewable essential resources. Water is one of the essential elements of human life as the body cannot survive longer than few days without adequate water (Alepu et al, 2016). The availability of adequate water supply both in quality and quantity is essential for human existence.…”

The research was carried out to assess heavy metal presence in borehole water used in eleme Port Harcourt Refinery host communities in Rivers State. The physicochemical parameters determined include: Temperature, pH, turbidity, alkalinity, and total dissolved solid (TDS) using conventional equipment and standard laboratory procedures, also the concentration of of Pb, Hg, Fe, CD, SO4, SO3, CO3 and Cl-, were determined using Atomic Absorption Spectrophotometer(AAS), bacterial analysis were carried out and characterized using standard methods. The results showed that physical parameters such as pH, temperature and turbidity in some communities did not show any reason for concern. The chemical parameters measured are within the World Health Organi-sation (WHO) and National Standard for Drinking Water Quality (NSDWQ) standard except for cadmium which show a very high concentration with the range of 0.13-0.48mg/l as compared to approved 0.003mg/lof World Health Organisation and 0.05mg/l of National standard for Drinking Water Quality respectively. Also, the concentration of iron (Fe) was very high in all the communi-ties sampled with the range of 0.19 -0.44mg/l as compared to approved 0.3mg/l of WHO and NSDWQ. The concentration of of Cadmium (Cd)detected was very high compared to the ap-proved standard of World Health Organisation and National Standard for Drinking Water Quality as it ranges from 0.00-0.4750mg/l. The presence of Cadmium may be due to the leaching of petro-leum and hydrocarbon compounds in the sampled area. Intervention of Government and Non- governmental Organisation is highly recommended.
