چکیده

هدف تحقیق، سنجش عناصر و ترکیبات سمی موجود در کفپوش‌های پلی‌اورتان مورد استفاده در اماکن ورزشی است. این تحقیق از نوع کاربردی و به روش آزمایشگاهی است. عناصر سنگین، منومر، هیدروکربن آزاد و ترکیبات فنولی اندازه‌گیری شدند. برای سنجش آلاینده‌ها از دستگاههای اسپکترومتر نشر اتمی پلاسما(ICP-OES) مدلVista Pro و اسپکتروفتومتر اشعه مرئی و ماورائ‌بنفش مدل 1240 mini استفاده شد. آزمایشات سه مرتبه تکرار شدند. برای تعیین حد مجاز مواجهه، از شاخص متوسط وزنی – زمانی (OEL-TWA) استفاده شد. اکسید کلسیم با ppm 125800 و سپس، پلی‌پروپیلن با ppm 5820 بیشترین میزان ترکیبات را شامل شدند. بالاترین میزان عنصر به ترتیب متعلق به فلز سنگین سرب برابر ppm 7990 و روی با ppm 5770 بود. نتایج نشان داد که اختلاف زیادی میان استاندارد و حد مجاز آلاینده‌ها با اعداد حاصل از آزمایشات وجود دارد. 2 آلاینده آرسنیک و کروم با قابلیت «سرطان‌زایی تایید شده انسانی» در ساختار کفپوش پلی‌اورتان شناسایی شدند. سیلیس نیز به عنوان «آلاینده‌های مشکوک به سرطان‌زایی در انسان»، شناسایی شد. سرب نیز به عنوان «سرطان‌زایی تایید شده برای حیوان با ارتباط ناشناخته بر انسان» شناسایی شد و 12 مورد بعنوان «غیرقابل طبقه‌بندی به عنوان یک عامل سرطان‌زای انسانی» سنجش شدند. برخی از عناصر و ترکیبات موجود در ساختار کفپوش‌های ورزشی، دارای رنجی بالاتر از استانداردها و حدود مجاز مواجهه هستند که این امر می‌تواند بر سلامت کاربران تاثیرگذار باشد و از سوی دیگر، امکان آسیب‌رسانی به محیط زیست را دارا است.

چکیده [English]

The purpose of this study is to evaluate the toxic elements and compounds present in polyurethane flooring used in sports venues. This research was applied and laboratory. Heavy elements, free monomer and hydrocarbons and phenolic compounds were measured. Vista Pro model ICP-OES and 1240 mini visible and ultraviolet spectrophotometer were used to measure the pollutants. The experiments were repeated three times and the weighted mean-time index (OEL-TWA) was used to determine the allowable exposure to chemical agents. Calcium oxide with 125800 ppm and then polypropylene with 5820 ppm included the highest amount of compounds. The highest element content belonged to lead heavy metal at 7990 ppm and zinc at 5770 ppm, respectively. The results showed that there was a large difference between the standard and the permissible level of pollutants and the numbers obtained from the tests. Two arsenic and chromium contaminants with "proven human carcinogenicity" were identified in the structure of polyurethane flooring. Silica has also been identified as a "contaminant suspected of carcinogenicity in humans." Lead was also identified as "confirmed carcinogenicity for animals with unknown association with humans" and 12 cases were rated as "unclassifiable as a human carcinogen".Some elements and compounds in the structure of sports flooring have a higher suffering than the standards and permissible exposure limits, which can affect the health of users and on the other hand, can be harmful to the environment.
