Article Citation - WoS: 10Citation - Scopus: 14Indoor Environmental Quality in Naturally Ventilated Schools of a Dusty Region: Excess Health Risks and Effect of Heating and Desert Dust Transport(Wiley, 2022) Şahin, Çağrı; Rastgeldi Doğan, Tuba; Yıldız, Melek; Sofuoğlu, Sait CemilIndoor air quality (IAQ) is impacted by polluted outdoor air in naturally ventilated schools, especially in places where both anthropogenic and natural sources of ambient air pollution exist. CO2, PM2.5, PM10, temperature, relative humidity (RH), and noise were measured in five naturally ventilated primary schools in City of Sanliurfa, in a dusty region of Turkey, Southeast Anatolia. Excess risk levels were estimated for particulate matter. Investigation was conducted through an educational year including two seasons in terms of anthropogenic effect, that is, heating/non-heating, and natural effect, that is, desert dust transport/non-dust transport. The median CO2 concentration was measured to be >1000 ppm in all seasons/schools. Temperature and RH fell out of the comfort zone in October-December, during which pollutant concentrations were considerably increased, specifically in November, that heating and dust transport periods coincide. The overall mean indoor PM10 and PM2.5 levels were 58 and 31.8 mu g/m(3), respectively. Risk assessment indicate that both short (incidence of asthma symptoms in asthmatic children) and long-term (prevalence of bronchitis) effects are considerable with 10.9 (2.4-19.6)% and 19.5 (2.2-38.8)%, respectively. The findings suggest that mechanical ventilation retrofitting with particle filtration is needed to mitigate potential negative health consequences on children.Article Citation - WoS: 20Citation - Scopus: 19Using the Turkish Red Pine Tree To Monitor Heavy Metal Pollution(HARD, 2020) Yalçın, Ertuğrul; Özyiğit, İbrahim İlker; Doğan, İlhan; Demir, Göksel; Yarcı, CelalTurkish red pine is an evergreen tree species widely distributed in the Aegean and Mediterranean regions in Turkey. In the present work, the heavy metal pollution level in Istanbul was investigated using Turkish red pine as a biomonitor. For determining heavy metal concentrations (Cd, Co, Cr, Mn, Ni and Pb) in leaf (unwashed and washed) and bark samples of Turkish red pine and its co-located soil samples we used ICP-OES. Additionally, particulate matter profiles of the research areas were investigated. The samples were collected from 5 different localities: 4 from the Bosporus region (Yildiz Grove, Fethi Pasha Grove, Baltalimani Grove and Mihrabad Grove) and one from Prince Island, also known as Buyukada (as control). According to our measurements, the highest heavy metal accumulations (in mg kg(-1) DW) in plant part samples were measured between 1.526 +/- 0.012 and 1.639 +/- 0.015 for Cd, 0.543 +/- 0.007 and 0.600 +/- 0.009 for Co, 5.110 +/- 0.064 and 5.648 +/- 0.072 for Cr, 9.347 +/- 0.105 and 10.331 +/- 0.111 for Mn, 7.483 +/- 0.091 and 8.271 +/- 0.096 for Ni, and 13.848 +/- 0.159 and 14.950 +/- 0.167 for Pb, while the highest heavy metal accumulations (in mg kg(-1) DW) in soil samples were measured between 1.813 +/- 0.021 and 1.974 +/- 0.029 for Cd, 6.326 +/- 0.082 and 6.992 +/- 0.091 for Co, 22.017 +/- 0.284 and 23.685 +/- 0.301 for Cr, 268.333 +/- 3.153 and 297.361 +/- 3.529 for Mn, 15.194 +/- 0.176 and 16.792 +/- 0.193 for Ni, and 68.778 +/- 0.715 and 74.514 +/- 0.883 for Pb. The highest outdoor particulate matter levels (in mu g/m(3)) in research areas were also determined as 27.103 for fine (PM2.5) and 67.792 for coarse (PM10) aerosols. The findings revealed that Turkish red pine could accumulate noteworthy amounts of heavy metals.Conference Object Determination of Metal Deposition and Its Effects on Mineral Nutrient Uptake Status of Pinus Brutia Ten. for Assessment of Pollution Impact in Its Habitat-Istanbul(Global Nest, 2013) Yalçın, İbrahim Ertuğrul; Demir, Göksel; Özyiğit, İbrahim İlker; Doğan, İlhan; Yarcı, CelalPinus brutia Ten. (Turkish red pine) is a widespread evergreen tree in the Mediterranean and Aegean regions of Turkey. In this study, leaf (washed and unwashed) and bark samples of Turkish red pine and its co-located soil samples were examined for the assessment of the impact of heavy metal pollution on mineral nutrient status of the plant. The samples were collected from 5 different localities; 4 from the Bosporus region and one from Prince Island (control) in 2012 vegetation period. The standard procedures were used and the determinations of heavy metals and nutrient elements (Al, B, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb and Zn) in all samples were done using Inductively Coupled Plasma Optic Emission Spectroscopy (ICP-OES). Additionally, PM2.5 and PM10 profiles of the study area were investigated. According to our measurements, the lowest and highest heavy metal accumulations and the amount of mineral nutrients (mg/kg d. wt) were varied between 28.420-115.809 and 4191.285-5776.910 for Al, 1.308-11.432 and 9.318-15.803 for B, 1604.497-9312.622 and 2457.361-4817.899 for Ca, 0.307-1.587 and 0.803-1.890 for Cd, 0.064-0.579 and 3.860-6.731 for Co, 0.853-5.445 and 12.472-22.761 for Cr, 2.063-11.292 and 8.304-24.193 for Cu, 158.090-242.056 and 4733.993-5727.813 for Fe, 88.021-4312.240 and 1231.649-1931.372 for K, 98.325-850.764 and 2668.299-4489.028 for Mg, 3.752-9.764 and 143.698-278.108 for Mn, 45.716-1315.764 and 91.225-116.795 for Na, 0.889-7.746 and 7.437-15.750 for Ni, 3.917-14.341 and 31.122-71.762 for Pb and 10.268-35.844 and 43.746-122.258 for Zn in the plant parts and soil samples, respectively. The mass concentrations of fine (PM2.5) and coarse (PM10) mode aerosols varied from 11 to 27 and 37 to 68 mu g/m(3) at study area, respectively. The data revealed that P. brutia is capable of accumulating considerable amounts of metals and mineral nutrient uptake pattern was not altered extensively because of metal deposition in the plant showing relatively less contamination risk in the area. Finally, it was proven that P. brutia is a suitable organism to be used as a biomonitoring tool for conducting research on heavy metal pollution.
