Publication Investigation of polycyclic aromatic hydrocarbons (PAHs) uptake by cucurbita pepo under exhaust gas loading(Taylor & Francis Ltd, 2022-02-21) Cihangir, Perihan; Durmuş, Hafize; Taş, Birol; Cindoruk, S. Sıddık; Cihangir, Perihan; Durmuş, Hafize; TAŞ, BİROL; CİNDORUK, SABAHATTİN SIDDIK; Bursa Uludağ Üniversitesi/Mühendislik Fakültesi/Çevre Mühendisliği Bölümü.; Bursa Uludağ Üniversitesi/Ziraat Fakültesi/Tarla Bitkileri Bölümü.; 0000-0001-7536-0332; EPC-0182-2022; IKM-6534-2023; EBF-7938-2022; GBB-7012-2022It was aimed to compare the uptake of PAHs (Polycyclic aromatic hydrocarbon) by Cucurbita pepo fruits exposed to exhaust gas or not in a greenhouse chamber. Cucurbita pepo vegetable was grown in two greenhouses, which were formed as control group and experimental group. The experimental group greenhouse was regularly exposed to exhaust gas for a certain period, no intervention was made to the control group. PAHs were measured in grown Cucurbita pepo samples and indoor air of greenhouse by passive air sampler (PAS). The average n-ary sumation (16)PAH concentration in Cucurbita pepo in the experimental group (exposed to exhaust gas) was 191.5 ng/g, compared with 124.8 ng/g in the control group (not exposed). The nearness of the vegetable to exhaust gas source were effective on the PAH levels. A significantly positive relationship (p < 0.05) was observed in PAH concentration between Cucurbita pepo and indoor air. It was found that PAH levels measured in the Cucurbita pepo vegetable were increased in proportion to PAH exposure, but this amount tended to decrease in the Cucurbita pepo growing sufficiently. Benzo(a)pyrene had the highest toxic equivalence value in health risk assessment calculations. A negative effect of excess foliation on plant growth rather than fruit production was observed under exhaust gas exposure.Publication Performance evaluation of diethylamine to the removal of polycyclic aromatic hydrocarbons (PAHs) from polluted soils with sunlight(Taylor, 2021-02-07) Eker, Gizem; Şengül, Burcu; Cindoruk, Sabahattin Sıddık; EKER ŞANLI, GİZEM; ŞENGÜL, BURCU; CİNDORUK, SABAHATTİN SIDDIK; Bursa Uludağ Üniversitesi/Mühendislik Fakültesi/Çevre Mühendisliği Bölümü; 0000-0003-0877-402X; 0000-0001-7536-0332; AAZ-1166-2020; CNL-8702-2022; JRB-1424-2023; GBB-7012-2022In the present study, the removal of polycyclic aromatic hydrocarbon (PAH) compounds from contaminated soil with solar radiation was investigated. In this context, the effect of diethylamine (DEA) as a photo-sensitizer on the photodegradation of PAH was examined, and the ring distributions of the PAHs were determined. DEA was added to samples at the doses of 1%, 10%, and 20% of dry weight of soil, and samples were kept in ambient air for 24 hours. Concentrations of sigma(12)PAH in soil samples were detected with Gas Chromatography-Mass Spectrophotometer (GC-MS) as 4382 ng/g dry matter (DM). The total PAH content of the soil decreased by 45% in the presence of sunlight without using DEA. sigma 12PAH removal efficiency was at the maximum level of 76% with the addition of 1% DEA to the soil. The increase in the dose of DEA adversely affected the PAH elimination process, and minimum removal ratio (32%) was obtained in the sample containing 20% DEA. The use of DEA has contributed to the elimination of most 3-ring PAH species. Heavy species, 5-6 ring compounds, have not been removed in the presence of sunlight.Publication Atmospheric volatile organic compounds levels in furniture-manufacturing city in Turkey(Elsevier, 2022-03-26) Çalışkan, Burak; Artun, Gülzade; Durmuş, Hafize O.; Gaga, Eftade O.; Cindoruk, S. Sıddık; ÇALIŞKAN, BURAK; Durmuş, Hafize O.; CİNDORUK, SABAHATTİN SIDDIK; Bursa Uludağ Üniversitesi/Mühendislik Fakültesi/Çevre Mühendisliği Bölümü.; 0000-0002-8729-9441; EUH-4552-2022; AAT-6526-2020; GBB-7012-2022Air pollutant emissions originated from industrial processes, combustion, and vehicles, significantly impacting air quality levels. In this study, Inegol-Bursa/Turkey, the city stands out with its furniture manufacturing sector, burning of hardboard wastes and dense traffic. Atmospheric volatile organic compound concentrations at 25 different points in Inegol city of Bursa were determined with passive air sampler. The city was classified according to its characteristics (organized industrial zone, residential areas, wastewater treatment plant, fuel-oil station and furniture industry zone). Different volatile organic compounds (45 species) were investigated in the atmosphere of the city. Volatile organic compound concentration in city air ranged from 17.1 to 133.6 mu g/m(3) and an average value of 59.5 +/-& nbsp;32.7 mu g/m3. Volatile organic compound concentrations were found to be higher, especially in industrial districts and near motorways. Lower concentrations than average volatile organic compound value were determined near the waste-water treatment plant, fuel-oil station and residential areas. The average of benzene, toluene, ethylbenzene and xylenes concentration for the city was determined as 34.7 +/- 19.5 mu g/m(3). The highest concentration of benzene, toluene, ethylbenzene and xylenes was found in industrial zone (89.8 mu g/m(3)) where the furniture industry and uncontrolled combustion were dominant. Benzene, toluene, ethylbenzene and xylenes concentrations obtained in this region were 2-6 times higher than the other sampling sites. In addition, cancer risk was calculated within the study's scope and the district risk was found to be at probable risk level.Publication 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-7012-2022In 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.
