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 R 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. R12PAH 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.

Ürünlerin imalat aşamalarında en az hammadde kullanımını amaçlayan ve sürdürülebilir bir endüstriyel sektör olarak tanımlanabilmektedir. Son birkaç yılda hem sosyal faydaları hem de çevre korumayı iyileştirdiği için araştırmacılar tarafından da dikkat çekmektedir. Karbon-nötr olma hedefini amaçlayan Avrupa Komisyonu 2019 yılında Avrupa Yeşil Mutabakatı anlaşmasını imzalamıştır. Ülkemizde de 2021 yılında imzalanan Yeşil Mutabakat, 2050 yılına kadar karbon emisyonundan arınmayı hedeflemektedir. Avrupa Mutabakatı kapsamında da kullanımının ve etkilerinin araştırılması yaygınlaşan elektrikli araçlar günümüzde de oldukça ilgi görmeye başlamıştır. Sera gazı azaltım hedefleri konusunda önemli katkı sunacağı düşünülen elektrikli araçların yaşam döngüsü değerlendirmesi yoluyla tüm çevresel etkileri belirlenerek değerlendirme ve yorumlama aşamaları sonunda elde edilmekte...

In this study, 18 surface soil samples were collected from five areas near wastewater treatment plants and landfills to investigate PCB levels. The observed PCB congener numbers and levels in the samples varied. The total PCB values were 5558±2856 pg g-1 dry weight (dw) (261PCB) for the marine outfall of the Buski Pretreatment Plant (Bursa Water and Sewerage Administration), 5386±1627 pg g-1 dw (245PCB) for the Hamitler Landfill Area, 3901±281 pg g-1 dw (235PCB) for the Western Wastewater Treatment Plant, 1824±448 pg g-1 dw (242PCB) for the Yesil Cevre Wastewater Treatment Plant, and 725±220 pg g-1 dw (217PCB) for the Eastern Wastewater Treatment Plant. These results show that the soils near the treatment plants were not completely contaminated by PCBs. At the sampling sites, with the biphenyls between 2 and 7 chlorine molecules and in particular, an abundance of homologue groups with 3, 4, and 5 chlorines were found. Moreover, dioxin-like PCBs (PCB#77, 81, 105, 114, 118, 123, and 126) were detected in all samples.

Clinical wastes should be handled, transported and disposed off properly for the health of peopie and environment. In this study present clinical waste managemeni in Bursa was studied by conducting polis in 12 pilot areas. Results of the polis indicated that clinical wastes are separated as domestic and infectious, but hazardous chemical wastes are not separated properly. Infectious wastes are disposed off by mixing with domestic solid wastes at present. However a project for the incineration of clinical wastes is being carried out by Bursa Municipality.

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/m3 and 772.92 ± 864.23 ng/m3, respectively. The concentrations in the particulate phase in the regions were 413.52 ± 430.23 ng/m3 and 342.40 ± 527.48 ng/m3, respectively. The average total (gas + particlulate phases) concentration of ∑16PAH determined in the site of FW was 1111.34 ± 1045.24 ng/m3 while that was 772.92 ± 864.23 ng/m3 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.

Seventeen precipitation samples were collected over a 1-year period from 2008 to 2009. Rainwater was accumulated at the beginning of rain events using real time monitoring. Atmospheric concentrations were also measured in parallel with deposition samples. Both atmospheric concentrations and deposition fluxes were determined as particle and gas phases. The particle phase and dissolved phase deposition fluxes were 794.26 ± 756.70 ngm-2 day-1 and 800.77 ± 672.63 ngm-2 day-1, respectively. The washout ratios for OCP compounds were calculated separately for the particle and dissolved phases using the atmospheric concentrations and rain concentrations. The minimum washout ratio for the particle phase was 2339.47 for Endrin aldehyde, whereas the maximum washout ratio was 497593.34 for Methoxychlor. The maximum washout ratio for the dissolved phase was 247523.89 for Endosulfan beta, whereas the minimum washout ratio was 10169.69 for p,p'-DDT. The dry deposition velocities ranged from 0.01 to 1.67 cms-1. The partitioning of wet deposition between the particle and dissolved phases was 50 % in terms of total OCP deposition.

A modified deposition sampler was used for dry and wet periods. Average dissolved and particle phase wet deposition flux values were determined to be 7.4 ± 7.3 μg/m 2 day and 21 ± 30 μg/m 2 day, respectively. The highest PAH wet fluxes were observed in the winter and fall seasons. Dissolved and particle phase rainwater concentrations of PAHs were 290 ng/L and 665 ng/L. The average of total (particle + gas) atmospheric concentration of ∑ 12 PAH was 130 ± 160 ng/m 3. In general, percentages of PAHs with five or more aromatic rings were bigger in particle phase in air. Average washout ratios of PAH compounds were determined 8.97 × 10 5 and 8.52 × 10 5 for gas and particle phase, respectively. Gas phase washout ratios of high molecular weight PAHs were greater than the lower molecular weight PAHs.

The overall average of fourteen bulk deposition fluxes for PAHs was 3300+/-5100 ng m(-2) d(-1). PAH depositions showed a seasonal variation and they were higher in winter months. This was probably due to increases in residential heating activities and decreases in atmospheric mixing layer levels. Ambient air samples, measured with a high volume air sampler, were collected from the same site. The average total concentration including gas and particulate phase was about 300+/-420 ng m(-3) and it was in the range of previously reported values. Some of the ambient air and bulk deposition samples were collected simultaneously in dry periods. Both concurrently measured values were used to calculate the dry deposition velocities whose overall average value was 0.45+/-0.35 cm s(-1).
