“…This brings the importance of determination of level of individual and or total VOCs in both outdoor and indoor environments. Several studies have shown an elevated level of VOC in or near workplaces such as printing press dyeing industry and school zones [ 15 , 16 , 17 , 18 ].…”

“…Majority of these sensors, cannot provide concentration of specific VOCs but offer real time monitoring or screening of total VOCs. They are being used in assessing indoor air quality in several environments such as printing press [ 15 ], university offices and rooms [ 26 , 27 , 28 ], nail salons [ 29 ], food industry [ 30 ] of different countries. These studies have reported an elevated level of TVOC and or individual VOCs in the workplaces.…”

Volatile organic compounds (VOCs) are one of the major contributors to poor indoor air quality. Due to advancements in sensor technologies, continuous if not regular monitoring total VOC (TVOC) and or some specific VOC in potential high risk workplaces is possible even in resource limited settings. In this study, we implemented a portable VOC sensor to measure concentration of TVOC and formaldehyde (HCHO) in six types of potential high risk workplaces (n ¼ 56 sites) of Katmandu Valley. For comparison, concentration was also measured in immediate surroundings (n ¼ 56) of all the sites. To get preliminary information on safety practices, a survey study was also conducted. The mean TVOC and HCHO concentration in the sites ranged from 1.5-8 mg/m 3 and <0.01-5.5 mg/m 3 , respectively. The indoor: outdoor TVOC and HCHO ratio (I/O) was found to be significantly higher (I/O > 1.5 and p < 0.05) in 34 (~61%) and 47 sites (~84%), respectively. A strong positive correlation between HCHO and TVOC concentration was observed in furniture industry (R ¼ 0.91) and metal workshops (R ¼ 0.98). Interestingly, we found TVOC and HCHO concentration higher than WHO safe limit in ~64% and ~32% sites, respectively. A rough estimate of chronic daily intake (CDI) of formaldehyde showed that CDI is higher than WHO limit in four sites. These findings suggested that indoor air quality in the significant number of the workplaces is poor and possible measures should be taken to minimize the exposure.

“…İnsan sağlığına zararlı etkileri nedeniyle halojenli organik bileşikler, UOB'ler arasında en az araştırılan ve analizi yapılan bileşik türüdür [14]. Ancak halojenli UOB'lerin özellikle klima veya merkezi havalandırma sistemleri çalışırken veya bakımları esnasında iç ortama sızdıkları bildirilmiştir [15]. Toksik kirleticilere çalışma ofislerinde uzun süre düşük konsantrasyonda maruz kalındığında dahi tehlike yaratmaktadırlar.…”

Fotokopi makineleri iç ortam hava kalite problemlerine yol açabilmektedir. Laboratuar ortamında test odasında yapılan çalışmalar fotokopi makinelerinin fotokopi işlemi süresince çok sayıda uçucu organik bileşiği (UOB) yaydığını göstermiştir. Bu çalışmada dört fotokopi merkezinden ve iki dış hava örneğinden alınan alan numuneleri aktif karbon tüplerinde toplanmış ve gaz kromatografisi-kütle spektrometresi kullanılarak NIOSH tarafından geliştirilen standart metoda göre analiz edilmiştir. Fotokopi merkezi 2'de 0,52-35,90 µg/m 3 aralığında 18 farklı uçucu organik bileşik belirlenmiştir. Maksimum konsantrasyon 77,59 µg/m 3 olarak (toluen, fotokopi merkezi 3) belirlenmiştir. Fotokopi merkezlerinde toplam uçucu organik bileşik maruziyeti 15,76-129,03 µg/m 3 .gün aralığında tespit edilmiştir.
