“…The procedure can, therefore, be used to determine a series of OCs with varying properties. Lower recoveries were found for some OPPs due to the loss during the evaporation steps (Barranco et al, 2003), the width of the GPC fractionating window (Navarro et al, 2006), and/or matrix effects. In addition, OPPs are prone to thermal degradation during analysis.…”

a b s t r a c tA high throughout semi-quantification method for screening nearly 900 organic contaminants (OCs) in river sediments has been developed. For most OCs tested, concentrations calculated from the proposed semi-quantification method deviated from actual values by a factor of 4. The overall recovery tests indicated that most OCs can be successfully extracted from sediments with recovery rates from 84.1 to 128.6%. To demonstrate the effectiveness of our method towards OC quantification, we screened OCs from sediments collected from the Haihe River basin. Seventy unregulated OCs (including pesticides, flame retardants, PPCPs, etc.) were identified and quantified at concentrations up to 2600 ng/g from 24 sediment samples. From these results, it is confirmed that the developed method is a useful way to fulfill a comprehensive analysis of OCs in sediments and would be valuable for the identification and prioritization of priority pollutants in watershed management.

“…Bu sonuçlar değerlendirildiğinde, hekzan en iyi elüsyon çözeltisi olarak seçildi ve tüm PAH'lar için geri kazanım yüzdeleri %94'ün üzerinde ve % bağıl standart sapma (BSS) değerleri <7.6 olarak hesaplandı. Literatürde yapılan diğer bir çalışmada da, C18 SPE kartuşları kulanılarak yapılan PAH ekstraksiyonu için elüsyon çözeltisi olarak hekzanın kullanıldığı görülmüştür [6].…”

“…Buna ek olarak, PAHlar pişirme, koruma ve depolamanın moduna bağlı olarak çok çeşitli et, balık, sebze ve meyvelerde bulunurlar. Doğada 100'den fazla PAH bulunmuştur; Bununla birlikte, Birleşik Devletler Çevre Koruma Ajansı (EPA) tarafından bunların oluşumu ve kanserojenliği göz önüne alındığında öncelikli kirletici olarak sadece 16 tanesi belirlenmiştir [6][7][8]. Bunların en tanınmışları benzo[a]piren (BaP)'dir.…”

“…To avoid interference in PAHs analysis, the extract should be purified. Conventional purifying methods such as solid-phase extraction (SPE) [11][12][13] or solid-phase micro-extraction (SPME) [14,15] were used for purification. Commercial SPE columns have a small capacity; thus, triglycerides was not removed completely.…”

Summary. This paper develops an instrumental analytical approach for detection of fourteen polycyclic aromatic hydrocarbons (PAHs) in edible oil samples using gel permeation chromatography (GPC) and ultra-high performance liquid chromatography (UHPLC) coupled with diode array detector (DAD), and fluorescence detector (FLD). The GPC was used to remove triglycerides from edible oil samples. The extracted samples were then detected using UHPLC-DAD-FLD. In order to obtain good separation and high reproducibility, the UHPLC-DAD-FLD experimental condition was optimized. The PAHs including three groups of isomeric PAHs can be separated completely in 12 min using BEH Shield RP 18 column with a suitable gradient elution program. The mean recoveries were in the range of 73-110% with an acceptable reproducibility (RSD < 10%, n = 3). During real sample analysis, the method can decrease the chance of false positives with both DAD and FLD being used simultaneously. The results indicate that the approach is simple, easy, and acceptably reproducible, thereby showing great potential as a method for detection of fourteen PAHs contained in edible oil samples.
