Abstract

In this study were
evaluated levels of organochlorinated pesticides and polychlorinated biphenyls
in extra virgin olive oil samples from Vlora region (South Albania), in January
2015. Vlora region is known for olive oil production. Organoclorinated
pesticides are used wide for agricultural purposes until 90’ in Albania. PCBs
were used in Albania as electric transformer oil after 90’ therefore these
compound were reported in many areas because of their atmospheric deposition. In
general these pollutants are stable compounds, lipophilic, withtoxic properties.
Ultrasonic bath extraction assisted with n-Hexane as organic solvent and two
clean-up steps have been used for analytical treatment of olive oil samples.
The quantitative analysis of organochlorinateds pesticides and PCBs were performed
by the gas chromatography method with electron capture detector. The profiles
of detected pesticides were: Endosulphanes > HCHs > Aldrines Mirex >
Methoxychlor > DDTs. PCB 28, the volatile PCB marker was the main congener
for all analyzed samples.  The levels of
contaminants observed for the olive oil samples could be because of their
before use for agricultural purposes, oil production proces, atmospheric
deposition for Vlora region.
