| چکیده | ||
| این مطالعه با هدف تعیین محتوی و ارزیابی مخاطره سلامت ترکیبات PAH به‌عنوان ترکیباتی ناهنجاری‌زا، جهش‌زا و سرطان‌زا در نمونه‌های گردوغبار داخلی تعدادی از ساختمان‌های اداری کلانشهر اصفهان در سال 1401 انجام شد. 84 نمونه گردوغبار از 28 مکان نمونه‌برداری جمع‌آوری شد. پس از استخراج آنالیت‌ها، نسبت به شناسایی و تعیین غلظت ایزومرهای PAH با استفاده از GC–MS اقدام شد. مقادیر شاخص خطر سرطان‌زایی مواجهه با گردوغبار آلوده نیز برای کودکان و بزرگسالان محاسبه شدند. نتایج بیان‌گر شناسایی 16 ایزومر دارای اولویت در نمونه‌ها با میانگین مجموع مقادیر برابر با 9838 میکروگرم در کیلوگرم بود. میانگین مقادیر فاکتور سرطان‌زایی مواجهه با گردوغبار آلوده به PAHs از طریق بلع، تنفس و تماس پوستی برای کودکان با 2-10 ⨯ 4.72، 13-10 ⨯ 6.96 و 2-10 ⨯ 5.89 و برای بزرگسالان نیز با 2-10 ⨯ 3.37، 12-10 ⨯ 2.62 و 2-10 ⨯ 5.99 برای هر دو گروه به‌ترتیب نشان‌دهنده "خطر سرطان‌زایی زیاد"، "خطر سرطان‌زایی ناچیز" و "خطر سرطان‌زایی زیاد" بود. همچنین، میانگین مقادیر شاخص توان سرطان‌زایی برای کودکان و بزرگسالان به‌ترتیب برابر با 1-10 ⨯ 1.06 و 2-10 ⨯ 9.36 بود. این در حالی است که میانگین مقادیر شاخص BaPeq با 705، نشان‌دهنده "خطر سرطان‌زایی فراتر از حد ایمن" بود. با توجه به این‌که قرار گرفتن در معرض ترکیبات PAH مخاطرات جدی بر سلامت زیستمندان برجای خواهد گذارد، نسبت به ردیابی، تعیین محتوی، منشاء‌یابی و پایش دوره‌ای این آلاینده‌ها در ماتریس‌های مختلف محیط‌زیستی و برنامه‌ریزی برای مدیریت منابع تولید و انتشار آن‌ها با هدف حفظ سلامت محیط و شهروندان توصیه می‌شود. | ||

| Polycyclic aromatic hydrocarbons (PAHs) with their teratogenicity, mutagenicity and carcinogenic characteristics can pose health risks for humans. Therefore, this study was conducted to determine the content and health risk assessment of PAHs in indoor dust samples of some office buildings in city of Isfahan in 2023. In so doing, a total of 84 indoor dust samples were collected from 28 sampling stations. After extraction of the analytes, the gas chromatography/mass spectrometry (GC–MS) method was used to determine the PAHs concentrations in the dust samples. Based on the results obtained, 16 priority PAHs were detected and quantified in the dust samples. The mean values of ∑16PAHs were found to be 9838 µg/kg. Total incremental lifetime cancer risks (ILCRs) of children and adults with average values of 1.06E-01 and 9.36E-02, were both classified in the 'high critical value' category. The cancer risk levels via dermal contact (5.89E-02) and direct ingestion (4.72E-02), indicated that both pathways greatly contributed to the cancer risk for children. Similarly, the risk value of dermal contact (5.99E-02) and direct ingestion (3.37E-02) were found to be important routes that adults could be exposed to contaminated dust with PAHs. Accordingly, the mean values of ILCRs ranked in the following order: dermal contact > direct ingestion > inhalation for both cases (i.e., children and adults). In conclusion, to maintain the health of both the man and the environment, it is recommended that regular and periodic analyses of these pollutants in different environmental matrices including soil, sediment, indoor and outdoor dusts, particulate matter, air, and water be performed to help prevent exposure risks of PAHs. | ||
