چکیده مقاله :
مقدمه و هدف پژوهش: امروزه کیفیت محیطی به عنوان یکی از پارامترهای مهم در مدیریت فضاهای ورزشی مطرح است. وجود آلاینده‌های محیطی می‌تواند بر سلامت و راندمان ورزشکاران اثرگذار باشد. هدف تحقیق، سنجش عناصر و ترکیبات سمی موجود در کفپوش‌های گرانولی مورد استفاده در اماکن ورزشی شهر شاهرود است.روش پژوهش: 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.یافته‌ها: ایزوپرن آزاد با ppm 3400 و سپس، دی‌اکتیل فتالات با ppm 3280 بیشترین میزان ترکیبات را شامل شدند. بالاترین میزان عنصر به ترتیب متعلق به فلز سنگین قلع برابر ppm 125000 و مس با ppm 75280 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 به عنوان غیرقابل طبقه‌بندی به عنوان یک عامل سرطان‌زای انسانی سنجش شدند. نتیجه‌گیری: 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.
Introduction and Objective: Nowadays, environmental quality is considered as one of the important parameters in the management of sports spaces. The presence of environmental pollutants can affect the health and efficiency of athletes.The aim of the research is to measure the elements and toxic compounds in the granular flooring used in the sports facilities of Shahrood city.Method: This research is applied and laboratory method.Heavy elements, monomer, free hydrocarbon and phenolic compounds were measured.To measure the pollutants, ICP-OES model Vista Pro and visible and ultraviolet spectrophotometer model 1240 mini were used.The experiments were repeated three times.Time-weighted average (OEL-TWA) was used to determine the exposure limit.Results: Free isoprene with 3400 ppm and then dioctyl phthalate with 3280 ppm included the highest amount of compounds.The highest amount of the element belonged to the heavy metal tin with 125,000 ppm and copper with 75,280 ppm, respectively.The results showed that there is a big difference between the standard and the permissible limit of pollutants with the numbers obtained from the tests.2 pollutants arsenic and chromium with "confirmed human carcinogenicity" were identified in the structure of polyurethane flooring.Silica was also identified as "pollutants suspected of carcinogenicity in humans".Lead was also identified as a "confirmed animal carcinogen of unknown relevance to humans" and 12 were assessed as "not classifiable as a human carcinogen".Conclusion: Some of the elements and compounds in the structure of sports flooring have a range higher than the standards and permissible limits of exposure, which can affect the health of users and, on the other hand, have the possibility of harming the environment.
