    Poor indoor air quality (IAQ) can cause several respiratory diseases and symptoms. In this study, IAQ of 121 homes located in 3 different towns of Canakkale, Turkey was monitored throughout a year. Target air pollutants were particulate matter, volatile organic compounds (VOCs), bioaerosols, and Carbon dioxide (CO2), as well as air temperature and humidity. Moreover, pulmonary functions of the occupants were measured on a monthly basis. Also, occurrence of sick building syndrome (SBS) symptoms and other health related data were gathered from the occupants by a detailed questionnaire. The SBS is a situation related to indoor air pollution in which the occupants of a building experience health or comfort related adverse effects that appear to be associated directly to the time spent in the sick building. Results of this study showed that the highest indoor air pollutant levels were observed in Can town and the lowest levels were observed in Central town. Indoor levels of bioaerosols, particulate matter, benzene, Cladosporium spp., and Penicillium spp. as well as pulmonary functions of the occupants showed statistically significant differences between the locations of the homes (p < 0.001). Factor analysis implied that both indoor and outdoor originated sources contributed to IAQ. Even though the predominant SBS symptoms varied seasonally and spatially among the study sites, fatigue, cold-flu like symptoms, and difficulty in concentration occurred frequently. Correlations were found among the occurrence of SBS symptoms, measured IAQ parameters, and personal factors (p < 0.05). Performing more studies from the health and IAQ points of view improve public awareness.

    INDOOR AIR QUALITY OF A CAFETERIA WITH A ROTOR TURBINE VENTILATOR (RTV) AND CROSS-CORRELATIONS BETWEEN INDOOR AIR POLLUTANTS, OCCUPANCY RATE AND METEOROLOGICAL PARAMETERS
    (Gh Asachi Technical Univ Iasi, 2018) Mentese, Sibel; Cotuker, Osman; Selcuk, Burak
    Indoor air quality (IAQ) improvement potential of rotor turbine ventilator (RTV) was researched by setting up an RTV on the outer part of the chimney of a kitchen, located in a windy city, Canakkale, Turkey. Efficiency of RTV was assessed by preliminary tests, conducted in a three-storey restaurant. After obtaining positive results in terms of airborne bacteria count (TBC) from these tests, long-term measurements were carried out in a cafeteria by air sampling before and after setting up the RTV. In addition to airborne bacteria measurements, concentrations of Total Volatile Organic Compounds (TVOC), Carbon monoxide (CO), Carbon dioxide (CO2), ozone and (fine and coarse) particulate matters (PM) were also measured before and after the RTV installation on the funnel of the cafeteria. Moreover, temperature and relative humidity were measured on-line, and the meteorological parameters were recorded. Furthermore, the number of people in the cafeteria during the air sampling was counted. After the RTV installation, levels of TBC, sum of PM, TVOC, and CO2 clearly decreased, while levels of ozone and CO showed no significant variation during the study. Overall, RTV has potential to improve IAQ, when combined with natural ventilation. In addition to examining the efficiency of RTV, cross-correlations were found among the air pollutants, meteorological/thermal comfort parameters, and the occupancy rate, regardless of the RTV installation. Moreover, statistically significant relationships (p<0.05) were found for number of people in the cafeteria and levels of both CO2 and TBC throughout the entire study.
