Original Title:
Συγκριτική μελέτη μεθόδων προκατεργασίας και προσδιορισμού πολυκυκλικών αρωματικών υδρογονανθράκων (PAH's) σε θαλασσινό νερό και ιζήματα
Translated title:
Comparative study of pretreatment methods and determination of polycyclic aromatic hydrocarbons (PAHs) in seawater and sediments.
Summary:
This paper deal with the presence of polycyclic aromatic hydrocarbons in
several areas along the shores of the Mediterranean.
Initially we learned about PAH, studying the physico-chemical properties and
the toxic effect, especially when they are in urban areas.
Afterwards, we came in contact with the basic techniques, through which we are
able to isolate these compounds from water and sediments for quality and
quantity detection.
The isolation technique of PAH’s, were followed by the presentation of modern
instrumental analysis techniques by which we manage to qualify and quantify
them, in water and sediments.
Finally, studying some specific quality and quantity papers of PAH’s research
in the Mediterranean basin (such as Egypt, Crete, Adriatic Sea, Spain), we
reached some conclusions as for as the cause of PAH’s presence in these areas.
Polycyclic aromatic hydrocarbon compounds tend to accumulate in sediments
rather than water. Concentrations of PAH compounds in a particular sediment can
range from μg kg-1 to g kg-1 levels depending on the proximity of the area to
PAH sources such as industries, municipalities, and on water currents.
Generally, the main source of contamination is not petroleum. Several ratios
between parent polycyclic aromatic hydrocarbons show that the sources of
hydrocarbons in the sediments are generally much more pyrolytic than
petrogenic.
