Abstract

Climate change also known as climate emergence is a major environmental problem of concern all over the world. The impact of climate change on the activities of urban dwellers in Warri has been studied. The study was aimed at determining the concentration of polycyclic aromatic hydrocarbons in water. The estimated acceptable daily intake for adults and children of these pollutants was also determined. Standard analytical methods for determining PAHs was employed according to United states environmental protection agency (US EPA) and World health organization (WHO). The results showed levels of chromatogram and mean concentration of sixteen (16) PAHs in water analyzed. It was observed that Acenanphthene and fluorine were the two PAHs in water sample with the range of 1.49 and 0.96ppm respectively. However, health impact assessment of treated water should be carried out to identify the hazards and risk factors that may be associated with PAHs in water. The current study established that the levels of Acenanphthene (Ace), acenaphthylene (Act) in borehole water were below the limits set by WHO, US EPA, WB and NEMA. The public health concern in terms of borehole water in warri south, south part of Nigeria industrial area of the country is therefore paramount to be monitored regularly as such level will bioaccumulate in these samples assessed with time and pose public threat.
