[ 1 ] - Recent Advances in Microextraction Methods for Sampling and Analysis of Volatile Organic Compounds in Air: A Review
Human exposures to volatile organic compounds (VOCs) are associated with a wide range of health problems. Due to these adverse effects of VOCs on the human health, determination of trace levels of VOCs is very important for accurate assessment of indoor and outdoor exposure. Solid phase microextraction (SPME), needle trap device (NTD) and hollow fiber- liquid phase microextraction (HF-LPME) are...
[ 2 ] - بررسی تأثیر کیتوزان در حذف ماده آلی اسید هیومیک از نمونه های آبی در فرآیند انعقاد الکتریکی با الکترود آلومینیم
زمینه و هدف: وجود اسید هیومیک در آب آشامیدنی می تواند به عنوان یک ترکیب پیش ساز سبب تولید ترکیبات جانبی گندزدایی گردد. این مطالعه با هدف ارزیابی تأثیر کیتوزان به عنوان کمک منعقد کننده کم هزینه و موثر در فرآیند انعقاد الکتریکی به همراه الکترود آلومینیم، برای حذف ماده آلی اسید هیومیک از محیط های آبی انجام شده است. روش بررسی: در این مطالعه تجربی، آزمایشات انعقاد الکتریکی با الکترود آلومینیوم در p...
[ 3 ] - Training Manual for Prevention of Covid-19 Disease among Hospital Personnel
Dear Editor In recent days, coronavirus disease (COVID-19) as a viral infection caused by the SARS-Cov-2 virus has become a pandemic disease and has created critical conditions worldwide [1]. According to previous studies on pathogenic viruses associated with acute respiratory distress syndrome, each virus has a specific virulence dose, which it is about 2×103-3×103 viral particles for the inf...
[ 4 ] - New Methods for Identifying Microorganisms as potential bioterrorism agents with Emphasis on Chromatography-Mass Spectrophotometry (GC-MS): Narrative Review
Today, with the development of microbiology, biotechnology, and cellular and molecular genetics, human knowledge of microorganisms has increased and the possibility of making biological weapons with pervasive effects has increased. On the other hand, bioterrorist events and the construction of laboratories and sites for the production of biological weapons in many developed and developing count...
[ 5 ] - Application of Arc-GIS for zoning of occupational exposure levels to respirable crystalline silica in crushing factories
Introduction: The silica crushing is a process based on crushing, screening and, granulation of various types of silica rocks. The inhalation of silica dust leads to silicosis by causing irreversible fibrosis in lung tissue. The crystalline silica is classified as a human carcinogenic (group I) by the IARC. Azandarian region is one of the largest silica production units in Iran with 40 silica c...
