BACKGROUND Polycyclic aromatic hydrocarbons (PAH) are considered to be one of the major contaminants of drinking water and natural water bodies. Some of the well documented polycyclic aromatic hydrocarbons that are water pollutants and were considered for analysis in this study included benzo[b]fluoranthene (BbF), benzo[k]fluoranthene (BkF), benzo[a]pyrene (BaP), benzo[g,h,i]perylene (BgP), and indeno[1,2,3-c,d]pyrene (InD). This study aimed at determining the levels of concentrations of basically five polycyclic aromatic hydrocarbons in 57 drinking water bodies located around Samsun, Ordu, Giresun, Çorum, Amasya, Kastamonu and Sinop provinces. MATERIALS AND METHOD In this study, the Environmental Protection Agency (EPA) method 550.1 for the determination of polycyclic aromatic hydrocarbons in drinking by Liquid-Solid Extraction (LSE) and High Performance Liquid Chromatography (HPLC) with Coupled Ultraviolet (CD) and Fluorescence Detection (FD) was used. Sampling procedures were done according to the validated method specified by the Turkish Ministry of Enivironment and Forestry. Prior to the determination of concentrations by HPLC, PAHs contained in the samples were separated from the solid phase by Solid-Phase Extraction (SPE). All data analyses were conducted using SPSS and Excel. RESULTS Obtained results from the investigation revealed that the average total PAH and benzo[a]pyrene (BaP) concentration levels in drinking water samples taken from the central districts of Samsun were 2.73 ± 1.51 and 0.35 ± 0.24 ng/L respectively. In drinking water samples taken from Ordu, Giresun, Çorum, Amasya, Kastamonu and Sinop, the average total PAH concentrations were found to be 5.85 ± 3.82 ng/L, 3.79 ± 1.27 ng/L, 1.08 ± 0.62 ng/L, 2.42 ± 1.04 ng/L; 1.92 ± 0.35 ng/L and 4.07 ± 2.33 ng/L respectively. The average (BaP) concentrations for the same named locations were determined as 0.97 ± 0.75 ng/L; 0.55 ± 0.29 ng/L; 0.11 ± 0.08 ng/L; 0.35 ± 0.10 ng/L; 0.14 ± 0.04 ng/L; 0.39 ± 0.23 ng/L, respectively. It is therefore evident that the values of PAH and BaP in drinking water were below the limits of 100 and 10 ng/L specified in the Regulation on Water Intended for Human Consumption. These values are below the set limits proposed by Turkish legislation and WHO. CONCLUSION All the results for drinking water, usable water and natural spring water were below the values specified in the Regulation on Water Intended for Human Consumption and WHO. The PAH content of the studied river waters as well were below the limits proposed by Turkish legislation and WHO.

土耳其萨姆松及其周边地区饮用水中多环芳烃（PAHs）的测定。

背景技术多环芳烃(PAH)被认为是饮用水和天然水体的主要污染物之一。一些有据可查的多环芳烃是水污染物，在本研究中被考虑用于分析，包括苯并[b]荧蒽 (BbF)、苯并 [k]荧蒽 (BkF)、苯并 [a]芘 (BaP)、苯并 [ g,h,i]苝 (BgP) 和茚并[1,2,3-c,d]芘 (InD)。本研究旨在确定萨姆松、奥尔杜、吉雷松、乔鲁姆、阿马西亚、卡斯塔莫努和锡诺普省周围 57 个饮用水体中基本五种多环芳烃的浓度水平。材料和方法 在这项研究中，环境保护署 (EPA) 方法 550。采用液固萃取 (LSE) 和高效液相色谱 (HPLC) 结合紫外 (CD) 和荧光检测 (FD) 测定饮用中多环芳烃的方法如图 1 所示。取样程序是根据土耳其环境和林业部规定的经过验证的方法进行的。在通过 HPLC 测定浓度之前，样品中所含的 PAH 通过固相萃取 (SPE) 从固相中分离出来。所有数据分析均使用 SPSS 和 Excel 进行。结果 调查结果显示，从萨姆松中部地区采集的饮用水样品中，平均总 PAH 和苯并[a]芘 (BaP) 浓度水平分别为 2.73 ± 1.51 和 0.35 ± 0.24 ng/L。在取自 Ordu 的饮用水样本中，Giresun、Çorum、Amasya、Kastamonu 和 Sinop，平均总 PAH 浓度为 5.85 ± 3.82 ng/L、3.79 ± 1.27 ng/L、1.08 ± 0.62 ng/L、2.42 ± 1.04 ng/L；分别为 1.92 ± 0.35 ng/L 和 4.07 ± 2.33 ng/L。相同命名位置的平均 (BaP) 浓度确定为 0.97 ± 0.75 ng/L；0.55 ± 0.29 纳克/升；0.11 ± 0.08 纳克/升；0.35 ± 0.10 纳克/升；0.14 ± 0.04 纳克/升；分别为 0.39 ± 0.23 ng/L。因此很明显，饮用水中 PAH 和 BaP 的值低于《人类用水条例》规定的 100 和 10 ng/L 的限值。这些值低于土耳其立法和世界卫生组织提出的设定限值。结论 饮用水的所有结果，可用水和天然泉水低于《人类用水条例》和世界卫生组织规定的值。所研究河水中的多环芳烃含量也低于土耳其立法和世界卫生组织提出的限值。
