Abstract

This study was designed to realized the hazardous effects on marine ecosystem and assess the impacts of (NORM) 238U, 232Th, and 40K radioactivity and Polycyclic aromatic hydrocarbons in petroleum industry at red sea coastline in Abu Zenima and Abu Rudeis sites. Polycyclic aromatic hydrocarbons(PAHs) individuals Naphthalene, Acenaphthalene, Acenaphthylene, Fluorene, phenanthrene and Fluoranthene were analysed with HPLC with fluorescence detection for sea water, sediments and marine organisms Bivalves, coral reef and starfish. HPGe gamma ray spectrometric technique used for measured the 238U, 232Th, and 40K radioactivity concentration in sea water, sediments and marine organisms Bivalves, coral reef and starfish in both Abu Zenima and Abu Rude is sites. The data revealed an increase in the 238U, 232Th, and 40K and (PAHs) individuals for sea water, sediments and marine organisms Bivalves, coral reef and starfish in Abu Zenima and Abu Rude is sites respectively as compared to international maximum allowable concentrations. On the other hand, 238U, 232Th, and 40K and (PAHs) individuals for sea water, sediments and marine organisms Bivalves, coral reef and starfish were recorded higher concentration levels in Abu Zenima sitesthan Abu Rudeis sites. The data revealed an increase in concentration of (NORM) 238U, 232Th and 40K and PAHs individuals for starfish and coral reef than bivalves marine organisms for both Abu Zenima and Abu Rudeis sites respectively as compared to international maximum allowable concentrations.
