چکیده

زمینه و هدف: بیوآئروسل‌ها به ذرات بیولوژیک منتقله توسط هوا گفته می‌شود که شامل ارگانیسم‌های زنده مانند باکتری‌ها، قارچ‌ها و متابولیت‌های ناشی از آن ها نظیر اندوتوکسین‌ها می‌باشند. این مطالعه با هدف تعیین تراکم و تنوع بیوآئروسل‌های باکتریایی در هوای داخلی مراکز اقامتی درمان سوءمصرف مواد و بررسی فاکتورهای تاثیرگذار بر روی غلظت آن ها انجام گرفت.

مواد و روش‌ها: این مطالعه با هدف بررسی تراکم و تنوع بیوآئروسل‌های باکتریایی در هوای محیط داخل ساختمان 11 مرکز اقامتی درمان سوءمصرف مواد با استفاده از نمونه بردار تک مرحله ای انجام شد. در مجموع 224 نمونه برداشت و اعداد کلنی‌ها شمارش و باکتری‌ها تعیین هویت شدند، در نهایت تراکم باکتری‌ها بر حسب CFU/m3 گزارش شد و داده‌ها توسط نرم افزار SPSS مورد تحلیل آزمون آماری ANOVA قرار گرفتند. 

یافته‌ها: نتایج نشان داد که میانگین تراکم کل بیوآئروسل‌ها CFU/m3، 721 بوده است که در 60 درصد موارد نمونه برداری بالاتر از حدود توصیه شده است. بیشترین درصد باکتری‌های شناسایی شده در نمونه‌های هوا استافیلوکوک اورئوس، استافیلوکوک اپیدرمیدس بود.

نتیجه گیری: تراکم باکتری‌های هوابرد در هوای فضاهای بسته موردبررسی بیش از مقادیر پیشنهادی ارایه شده توسط WHO ( CFU/m3 500 ) بود که می‌تواند باعث خطرات بهداشتی و بیماری‌های تنفسی گردد. می‌بایست کنترل و حضور افراد، استفاده از شیوه‌ها و مواد گندزدایی مناسب جهت ضدعفونی کردن سالن‌ها، ایجاد سیستم‌های تهویه استاندارد و مناسب، طراحی و اجرا گردد.

چکیده [English]

Background and Purpose: Bioaerosols are airborne particles that include living organisms, such as bacteria and fungi, and their related metabolites, including endotoxins. This study aimed to investigate the exposure of individuals to bacterial bioaerosols in indoor air and explore the factors influencing their concentration.

Materials and Methods: This research was conducted across 11 wards of the Camp Collection to assess indoor air quality. A total of 224 samples were analyzed. The resulting bacterial colonies were counted, and bacterial density was expressed as colony-forming units per cubic meter (CFU/m³). The data obtained were analyzed using SPSS, ANOVA.

Results: The mean bacterial concentration was 721 CFU/m³. The most prevalent bacteria identified in the air samples were Staphylococcus aureus and Staphylococcus epidermidis.

Conclusion: In some environments, the bioaerosol concentration in indoor air exceeded the World Health Organization (WHO) guidelines, posing health risks and increasing the likelihood of respiratory diseases. To mitigate these risks, it is recommended to control individual traffic, modify disinfectant types and application procedures on ward surfaces, and establish the standard and suitable ventilation systems.
