چکیده

زمینه و هدف:  ترکیبات بتیکس از مهمترین آلاینده‌های شیمیایی هوای محیط کار در صنعت نفت هستند که اثرات سوء بهداشتی بر کارکنان این صنعت دارند. این پژوهش با هدف ارزیابی و سنجش غلظت ترکیبات بتیکس و اثرات احتمالی آن‌ها بر پارامترهای تنفسی کارکنان شرکت پالایش نفت آبادان انجام شد. 

مواد و روش‌ها: در این مطالعه 80 کارگر مورد بررسی قرار گرفتند. نمونه‌برداری از ناحیه تنفسی کارکنان مواجهه‌یافته بر اساس روش 1501 سازمان نایوش (NIOSH) با استفاده از پمپ نمونه‌برداری فردی فعال شرکت SKC انگلستان مدل 44-224 MTX  و با استفاده از تیوب‌های جاذب زغال فعال  SKC(مدل 01-226) انجام شد و سنجش پارامترهای تنفسی توسط دستگاه اسپیرومتری میکرولب ساخت کشور ایتالیا از کمپانی MIR انجام شد.

یافته‌ها: نتایج ، نشان دادند که میانگین غلظت ترکیبات تولوئن، اتیل بنزن و زایلن در ناحیه‌ی تنفسی کارکنان مواجهه‌یافته پایین‌تر از حد مجاز استانداردها قرار دارد اما میانگین غلظت ترکیب بنزن بالاتر از حد مجاز قرار دارد. نتایج نشان دادند که تفاوت معنی‌داری بین پارامترهای تنفسی دو گروه کارکنان وجود ندارد و بین میانگین پارامترهای تنفسی FEV1 با FVC در دو گروه کارکنان ارتباط مستقیم و معناداری وجود دارد و هیچ ارتباط معنی‌داری بین پارامترهای تنفسی و مشخصات دموگرافیک در دو گروه را مشاهده نشد. 

نتیجه‌گیری: با توجه به این‌که میانگین غلظت ترکیب بنزن بالاتر از حدمجاز استانداردهای توصیه‌شده قرار دارد، برای کنترل آن نیاز است که از راه کنترل‌های فنی مهندسی و مدیریت، بازرسی‌های دوره‌ای اقدام لازم برای کاهش غلظت و حذف این ترکیب صورت پذیرد.

چکیده [English]

Background and Purpose: BTEX compounds are one of the most important chemical air pollutants in the oil industry, which have adverse health effects on the employees of this industry. This research was conducted with the aim of evaluating and measuring the concentration of BTEX compounds and their possible effects on the respiratory parameters of the employees of Abadan Oil Refining Company.

Materials and Methods: In this study, 80 workers were examined. Sampling of the respiratory area of the exposed workers was performed according to the NIOSH method 1501 using an active personal sampling pump of SKC UK company, model 44-224 MTX and using SKC activated carbon absorbent tubes(model 226-01) and the measurement of respiratory parameters was done by a microlab spirometry device made in Italy by MIR company.

Results: The results showed that the average concentration of toluene, ethylbenzene and xylene compounds in the respiratory area of the exposed workers is lower than the standard limit, but the average concentration of benzene compound is above the limit. The results showed that there is no significant difference between the respiratory parameters of the two groups of employees, and there is a direct and significant relationship between the average respiratory parameters of FEV1 and FVC in the two groups of employees, and there is no significant relationship between the respiratory parameters and demographic characteristics in the two groups. It didn't happen.

Conclusion: Considering that the average concentration of benzene compound is higher than the permissible limit of the recommended standards, to control it, it is necessary to take necessary measures to reduce the concentration and remove this compound through technical engineering and management controls, periodic inspections.
