“…Furthermore, Table 1 shows that relative humidity has positive correlation coefficients of 0.162, 0.455, and 0.449 with NO, NO2, and NOx, respectively. This result is similar to those reported in other studies [23], [24]. This behavior is in line with the fact that the relative humidity falls when the temperature rises [25].…”

NOx, NO and NO2 concentrations, and meteorological parameters, temperature, wind speed, relative humidity and pressure were measured simultaneously and continuously in Dhahran (Saudi Arabia) during three months in summertime. The hourly and daily NOx, NO and NO2 average concentrations were investigated as a function of the meteorological parameters. NOx, NO, and NO2 were found to have a common source and to be highly influenced by traffic emission and meteorological conditions, and the trend of NO showed a higher concentration during weekdays than weekends. NOx has significant positive correlation coefficients with NO and NO2, respectively. Similarly, NO2 also has a positive correlation coefficient with NO. The temperature and wind speed showed negative correlation coefficients while relative humidity showed positive correlation coefficient with NOx, NO and NO2. On the other hand, NO2 was found to exceed international air quality standards, which indicates the existence of a possible NO2 air pollution problem in Dhahran.

“…Bu kaynaklardan ortam havasına verilen başlıca kirleticiler,  Partiküler maddeler (PM)  Kükürt dioksit (SO2)  Karbon monoksit (CO)  Azot oksitleri (N0x)  Hidrokarbonlar (VOC ler) olarak sayılabilmektedir [1,2,3].Son yıllarda yapılan çeşitli çalışmalar, insanların atmosferik kirleticilere maruziyetinin solunum ve kalp rahatsızlıklarının artışında etkili olduğunu göstermektedir. Bu durumda kirleticilerin yoğun olarak görüldüğü kentsel alanlarda atmosferik kirleticilerin davranışlarının incelenmesi, hava kirliliğinin azaltılması ve halk sağlığının korunması hususunda etkin politikaların oluşturulması açısından önemlidir [4].…”

ÖzetÇalışmanın amacı, Balıkesir İli Burhaniye İlçesi İskele Mahallesi'nde hava kalitesinin izlenmesi ve değerlendirilmesidir. Bu kapsamda, Çevre ve Şehircilik Bakanlığı'na ait mobil ölçüm aracı kullanılarak hava kalitesine yönelik ölçüm çalışması yapılmıştır. Çalışma 08.03.2012 ile 22.03.2012 tarihleri arasındaki 15 günlük süreyi kapsamakta olup bu süreçte saatlik bazda SO2, NOx, CO, O3 ve VOC'ler izlenmiştir. Elde edilen sonuçlar hava kalitesi indeksine göre değerlendirildiğinde, PM10 parametresi bakımından 2 (iyi) -3 (yeterli) -4 (orta) aralığında, SO2 parametresi bakımından, 1 (çok iyi) ve 2 (iyi) aralığında, NO2 parametresi bakımından, 1 (çok iyi), CO parametresi bakımından, 1 (çok iyi), ozon parametresi bakımından, 1 (çok iyi) olduğu anlaşılmıştır. VOC parametreleri bakımından ise her ne kadar indeks olmamakla birlikte, uluslararası yapılmış ölçümlere bakıldığında, ölçülmüş en düşük değerlere yakın sonuçların bulunmuş olduğu, bu itibarla da, indeks şeklinde değerlendirildiğinde 1 (çok iyi) şeklinde nitelendirilebileceği görülmüştür.

In this context air quality measurements were conducted by means of Ministry of Environment and Urbanizations' mobile air quality measurement vehicle. Study was carried on fifteen days time interval between the 08.03.2012-22.03.2012 and SO2, NOx, CO, O3 and VOCs parameters were monitored hourly. When the gained results were evaluated according to air quality index, in terms of PM10 parameter, quality was determined between 2 (high)-3 (enough)-4(medium), in terms of SO2 parameter, quality was determined between 1 (very high)-2 (high), in terms of CO and O3 parameters, quality was determined as 1 (very high). Although there is no quality index for VOCs, when the results were compared with the measurements in literature, it was determined that the measured concentrations were very low and it was evaluated as 1 (very high).

“…The study was performed in the greater area of Athens basin, which has been characterized by documented high ozone levels, especially in non-traffic and suburban areas [4,35,36]. In particular, higher ozone concentration is observed in the northern and eastern parts of the basin, as a result of photochemical transformation processes involving precursor substances excessively produced in the densely populated city center and in the port area of Piraeus, the transport of which is aided by the frequent prevalence of southeasterly seabreeze mesoscale circulations [37].…”

Commuters’ Personal Exposure to Ambient and Indoor Ozone in Athens, Greece

2017

This pilot study aimed to monitor the residential/office indoor, outdoor, and personal levels of ozone for people living, working, and commuting in Athens, Greece. Participants (16 persons) of this study worked at the same place. Passive sampling analysis results did not indicate any limit exceedance (Directive 2008/50/EC: 120 µg/m 3 , World Health Organization (WHO) Air Quality Guidelines 2005: 100 µg/m 3 ). The highest "house-outdoor" concentration was noticed for participants living in the north suburbs of Athens, confirming the photochemical ozone formation at the northern parts of the basin during southwestern prevailing winds. The residential indoor to outdoor ratio (I/O) was found to be significantly lower than unity, underlying the outdoor originality of the pollutant. The highest "office-indoor" concentration was observed in a ground-level building, characterized by the extensive use of photocopy machines and printers. Personal ozone levels were positively correlated only with indoor-office concentrations. A clear correlation of personal ozone levels to the time spent by the individuals during moving/staying outdoors was observed. On the other hand, no correlation was observed when focusing only on commuting time, due to the fact that transit time includes both on-foot and in-vehicle time periods, therefore activities associated with increased exposure levels, but also with pollutants removal by recirculating air filtering systems, respectively.
