Os hidrocarbonetos poliaromáticos (PAHs) foram analisados em sedimentos recolhidos no Golfo de Suez, no Egito. As concentrações de ∑PAH variaram entre 6,6009 e 9442,803 ng/g de peso seco, com um valor médio de 1157,9793 ng/g de peso seco. A maior concentração total de HAP foi registada em sedimentos recolhidos na entrada da Suez Oil Petroleum Company (SOPC) 9442,803 ng/g de peso seco, seguida pela concentração registada 50 m a leste da saída da Suez Oil Petroleum Company (SOPC) 5183,466 ng/g de peso seco e na saída da Suez Oil Petroleum Company (SOPC) 1770,3265 ng/g de peso seco; enquanto concentrações mais baixas são detectadas na Praia de Suez 6,6009 ng/g de peso seco, 600 m a oeste da saída da Suez Oil Petroleum Company (SOPC), 300 m da entrada da AL-Nasr Petroleum Company (NPC ) e EL- Sukhna da Praia de Loloha (16,8135, 47,4581 e 65,0644 ng/g de peso seco, respetivamente). Neste contexto, a relação entre o baixo peso molecular dos HAP (2 e 3 anéis) e o alto peso molecular (4 a 6 anéis) foi utilizada para diferenciar as fontes pirogênicas e petrolíferas dos HAP nas amostras estudadas.
