DETERMINATION OF PAHS AVAILABLE IN DRINKING WATER SOURCE FROM MODERN TRAINING INSTITUTE, OFF AKA ROAD, UYO, AKWA IBOM STATE
Abstract
This study investigated the presence of polycyclic aromatic hydrocarbons (PAHs) in the drinking water source of Modern Training Institute, off Aka Road, Uyo, Akwa Ibom State. Water samples were analyzed for five PAHs: naphthalene, anthracene, phenanthrene, fluoranthene, and pyrene. The results showed detectable concentrations for all PAHs, with phenanthrene exhibiting the highest mean concentration (0.21 ± 0.01 µg/L) and anthracene the lowest (0.08 ± 0.01 µg/L). All measured values were below the U.S. Environmental Protection Agency (EPA) recommended water quality criteria, indicating low immediate health risk through ingestion. The presence of PAHs, however, highlights potential chronic exposure concerns due to their persistence and bioaccumulative properties. The study provides baseline data for the water quality at the institute, emphasizing the need for routine monitoring, comprehensive PAH profiling, and evaluation of water treatment efficiency to ensure safe drinking water. These findings contribute to understanding PAHS contamination in drinking water sources in scool settings.
