Due to the growing consumption of petroleum products, oil pollution is increasingly frequent in aquatic ecosystems. Petroleum hydrocarbons are important pollutants for sea and marine organisms. Many researches about petroleum effects on aquatic systems regards the immediate and short-term toxic effects. The origin of hydrocarbons are either endogenic, which are synthetised by marine organisms or exogenic, due to oil pollution accumulated by marine organisms. This paper evaluates the results of research effects of petroleum hydrocarbons on some algae and plant organisms. The analsysis have been recorded by using total organic carbon (TOC) Fourier transform infrared spectroscopic measurements (FTIR), inductively coupled plasma atomic emission spectroscopy (ICP-AES).

Avand in vedere consumul in crestere de produse petroliere, poluarea cu petrol este din ce in ce mai frecventa in ecosistemele acvatice. Hidrocarburile petroliere sunt cei mai importanti poluanţi pentru organismele marine si plantele marine. Numeroase studii au fost prezentate despre efectele toxice ale produselor petroliere asupra sistemelor acvatice pe termen lung sau scurt. Originea hidrocarburilor poate fi de endogena sau exogena. Aceasta lucrare evalueaza rezultatele efectelor hidrocarburilor petroliere asupra a doua tipuri de alge, din zone diferite. Au fost inregistrate rezultate cu ajutorul metodelor TOC (carbon organic total), spectrometrie in infrarosu cu transformata Fourier (FTIR), spectrometrie de emisie cu plasma cuplata (ICP-AES).
