Radiological Impacts of NORM and Poly Aromatic Hydrocarbon in Petroleum Industry Process on Marine Ecosystem at the Red Sea, Egypt

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  The²³⁸U, ²³²Th, and ⁴⁰K radioactivity concentration in sea water, sediments and marine organisms Bivalves , coral reef and starfish in both Abu Zenima  and Abu Rudeis 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 Rudeis 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 organismsBivalves , 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.
