Abstract
Effluents from Nigerian National Petroleum Corporation (NNPC) depot in Calabar, Cross River State, Nigeria were evaluated for some physicochemical parameters and hydrocarbon content. The physicochemical parameters of effluents were all below Federal Ministry of Environment (FMEnv) permissible limits except for temperature which was +0.2°C above the standard for temperature of 30.0°C, THC value for the effluent was 0.8mg/l. It was observed that the physicochemical parameters of the depot’s effluent were below FMEnv’s standards which make it safe for discharge. Environmental Regulatory Agencies should therefore ensure compliance from firms, industries, plants and oil depots (oil terminals) which generate effluents by frequent monitoring of their activities.
Keywords: Effluent, physico-chemistry, hydrocarbon, permissible limits
