    Pah levels in a furniture-manufacturing city atmosphere
    (Elsevier, 2020-02-01) Çalışkan, Burak; Küçük, Aleyna; Taşdemir, Yücel; Cindoruk, Sabahattin Sıddık; ÇALIŞKAN, BURAK; Küçük, Aleyna; TAŞDEMİR, YÜCEL; CİNDORUK, SABAHATTİN SIDDIK; Bursa Uludağ Üniversitesi/Mühendislik Fakültesi/Çevre Mühendisliği Bölümü; 0000-0002-8729-9441; 0000-0002-6192-8609; 0000-0001-7536-0332; AAT-6526-2020; AAG-9468-2021; JHH-5032-2023; GBB-7012-2022
    In this study, in order to determine atmospheric PAH concentrations in Inegol/Turkey, ambient air samples were collected from two different sites representing industrial and uncontrolled furniture manufacturers regions. Sampling campaign took place between December 2017 and November 2018. Air samples were collected using high volume air samplers (HVAS) and PAH concentrations were determined in both gas and particulate phases. The mean of the atmospheric PAH concentrations obtained in the gas phase in the furniture workshops (FW) and industrial district (ID) regions were 697.82 +/- 637 ng/m(3) and 772.92 +/- 864.23 ng/m(3), respectively. The concentrations in the particulate phase in the regions were 413.52 +/- 430.23 ng/m(3) and 342.40 +/- 527.48 ng/m(3), respectively. The average total (gas + particlulate phases) concentration of Sigma(16)PAH determined in the site of FW was 1111.34 +/- 1045.24 ng/m(3) while that was 772.92 +/- 864.23 ng/m(3) in ID. These values are over the ambient levels reported for urban sites wherein big industries exist around the world. Additionally, the average of particle phase percentage was 30% because of nearby combustion sources. The determination of possible sources of PAHs in the regions was performed using principal component analysis (PCA). PCA results showed that the main sources of pollutants of the regions are intertwined (combustion, traffic, industries). However, the most effective source is thought to be uncontrolled combustion of furniture wastes as fuel for residential heating. Health risks for the citizens were calculated for both regions and were found not to be at high-class risk.

    Air quality level, emission sources and control strategies in Bursa/Turkey
    (Turkish Natl Committee Air Pollution Res & Control-tuncap, 2020-12-01) Çalışkan, Burak; ÇALIŞKAN, BURAK; Özengin, Nihan; ÖZENGİN, NİHAN; Cindoruk, S. Sıddık; Bursa Uludağ Üniversitesi/Mühendislik Fakültesi/ Çevre Mühendisliği Bölümü.; 0000-0002-8729-9441; 0000-0001-7536-0332; AAH-1475-2021; AAT-6526-2020
    In parallel with rapidly increasing population and number of motor vehicles, irregular urbanization, and unplanned industrialization, air pollution has reached dangerous levels in developing cities. Various industries such as textile, automotive, chemical, rubber and plastic industries are located in Bursa. In addition, the region receives a lot of migration and there is an intensive air pollution problem due to dense urbanization. The air quality monitoring station results showed that the PM10 and NOx are the main pollutants reducing air quality in the city. Despite the much efforts and regulations, air quality level has been getting worst year by year. Stakeholders were brought together to explore the true causes of non-blocking emissions, identify resource loads and priorities, and develop solutions. The current level and variation of air pollutant concentrations depending on years were presented to stakeholders. A survey and discussion were performed within the workshop, and consequently; industry, transportation, heating and uncontrolled combustion activities came front. Especially the fact that the industry is located in the city and the transportation network of the city is inadequate has emerged as the main source of air pollution problem. In order to develop effective solution, it was emphasized that effective supervision should come to the forefront and new industrial facilities should not be established in the regions in or near the city.
