Abstract

The increasing of development in countries with high populations is associated with several impacts on the environment due to human wastes. The present work aimed to assessment of environmental contamination of sea water which received untreated sewage effluents generated from Sabratah city since 1998. The study investigated the physical and chemical characteristics of sea water at the disposal point and inside the sea during the period from May 2014 to February 2015. The sampling points were determined using GPS Map 60 CX. Chemical Oxygen demand (COD), Biological Oxygen demand (BOD5), total dissolved salts (TDS) and nitrogen were determined using international standards methods of water and wastewater. The maximum concentration of COD, BOD and nitrogen was determined at the discharge point, it was 473, 140 and 263 mg L-1, respectively. Among the heavy metals investigated, the highest concentrations were determined for Fe (0.89 mg L-1). It can be concluded that the discharge of untreated sewage into the sea water has an adverse effects on the aquatic organisms diversity in the marine environment and might effect on the human health via consumption of contaminated fishes.
