中文摘要： 本文旨在检测突尼斯橄榄和初榨橄榄油中烃类污染物（多环芳烃(PAHs)、饱和矿物油碳氢化合物(MOSH)、芳烃化合物(MOAH)和聚烯烃低聚物饱和烃(POSH)）。本文橄榄果实样本来不同环境，橄榄油通过物理提取器和微波萃取溶剂两种方法进行萃取；然后采用净化硅胶盒固相萃取，荧光光谱法检测多环芳烃，高效液相-气相色谱法检测饱和矿物油碳氢化合物(MOSH)、芳烃化合物(MOAH)和聚烯烃低聚物饱和烃(POSH)。检测结果显示，通过溶剂从橄榄中提取的MOSH比通过物理提取器提取的高出四倍，分别为11.1 mg/kg和2.6 mg/kg。市售的初榨橄榄油中MOSH的浓度范围为10.3-38 mg/kg，未检测到芳烃化合物。由于橄榄油处理和（或）包装，市售橄榄油中含有更高浓度的MOSH。两个样本中均明显含有由塑料盖迁移的聚烯烃低聚烃污染。
外文摘要：The present paper investigated on the presence of some hydrocarbon
contaminants, namely polycyclic aromatic hydrocarbons (PAHs), mineral
*oil* hydrocarbons (MOH) comprising saturated (MOSH) and aromatic (MOAH)
compounds, and polyolefin oligomeric saturated hydrocarbons (POSH) in
olives and extra virgin olive oils from Tunisia. Olive fruits were
collected in sites exposed to different environmental contamination, and
the *oil* extracted both by physical mean (using an Abencor extractor)
and with solvent (using microwave assisted extraction, MAE). Analytical
determination was performed by SPE cleanup on silica cartridge followed
by spectrofluorometric detection, for PAH, and on-line HPLC-GC-FID for
MOH and POSH. Oils extracted from olives by physical mean, as well as
extra virgin olive oils from the market, had PAH levels never exceeding
the EU legal limits. All olive samples showed similar MOSH profiles, but
not clear correlation between the variable contamination levels and
considered sources of contamination, was evidenced. The average MOSH
content in *oil* extracted from olives by solvent (11.1 mg/kg) was about
four time higher than in *oil* extracted by physical mean (2.6 mg/kg).
MOSH in extra virgin *oil* from the market ranged from 10.3 to 38.0
mg/kg, while MOAH were not detected. The higher MOSH levels found in
oils from the market evidenced an important contribution due to *oil*
processing and/or packaging. Two of the samples were clearly
contaminated with polyolefin oligomeric hydrocarbons (POSH) migrated
from the plastic cap. (C) 2016 Elsevier Ltd. All rights reserved.
