Source Apportionment of Hydrocarbons in Ghana's Coastal Sediments : Utilizing Hydrocarbons Ratios and Advanced Statistical Methods

This study presents a comprehensive analysis of hydrocarbon pollution in Ghana’s coastal sediments, with a focus on aliphatic hydrocarbons and polycyclic aromatic hydrocarbons. The primary objectives were to identify the sources of hydrocarbon pollution, assess its extent, and understand its im...
