Modeling and Assessment of PM10 and Atmospheric Metal Pollution in Kayseri Province, Turkey

Air pollution has numerous detrimental consequences for human health, visibility, climate, materials, plant health, and animal health. A portion of air pollution consists of metals, which are emitted into the environment via the combustion of fossil fuels, industrial activities, and the incineration of metal-containing products. In this work, the particulate matter and particle-related metal pollution from various sources, in the Turkish province of Kayseri, were determined. AERMOD modeling was also used to examine the distribution of PM10 around the Kayseri Organized Industrial Zone (OIZ). Particulate matter (PM10) samples were collected using MCZ dust collecting devices at six monitoring locations mainly affected by residential heating (Hürriyet, Talas, and Kocasinan), industry (OIZ), and traffic (Tramway and Cumhuriyet) during the autumn/winter months and at three monitoring locations mainly affected by residential heating (Kocasinan), industry (OIZ), and traffic (Tramvay) during the spring months. ICP-MS analysis was used to assess the concentrations of the heavy metals (Pb, As, Cd, and Ni) in samples collected over 6 different time periods of 16 days each. During the autumn/winter months, the concentrations of Pb near roadways were found to exceed the Air Quality Assessment and Management Regulation of Turkey (AQAMR) limit value. During all the sampling periods, the Ni and Cd concentrations were below the AQAMR limit values. At the points associated with winter heating, the concentrations exceeded the AQAMR limit value, which may result from coal combustion

Evaluation of Outdoor Environment PM₁₀ Concentration in an Organized Industrial Zone Using Geographical Information System

Air pollution adversely affects human health, visibility distance, materials, plants and animal health. Air pollution’s impact on human health arises from inhaling high amounts of harmful substances in the atmosphere. Notably, our understanding of the damage caused by PM10 pollutants is improving daily. This study aims to measure and analyze PM10 pollution in the Konya Organized Industrial Zone at certain times and places. Measurements were taken at twenty-four locations in the morning, noon and evening hours. The results were compared with the Turkish Air Quality Assessment and Management Regulation, and pollution maps of the regions were created with Surfer Software and ArcGIS 10.1 programs. With the measurements, it was observed that the times at which the limit was exceeded were mainly the evening hours. While no limit exceedance was recorded in the morning hours, the average concentration value was observed once in those hours, and around noon the maximum value was observed five times. In this study, we correlated the measurement results, the values of the measurement points located in the city center and the average number of vehicles passing through the region. It was observed that the PM10 -induced air pollution in the Konya Organized Industrial Zone was caused by dense traffic during evening hours. To prevent traffic-related pollution in the region, it is recommended to increase the number of entrance and exit gates in the industrial zone and to plant trees in appropriate sections

2020 mayıs ayındaki kum fırtınası sırasında Konya Selçuklu ilçesinde ölçülen PM konsantrasyonlarının istatistiksel analizi ve değerlendirilmesi

Dust storms are widespread events that occur several times a year and spread over many countries of the world relating the wind direction and speed. Especially particulate matter (PM) is the main pollutant spread over by these storms. Because of the dust storms, PM concentrations increase rapidly in the areas found on the way of dust storm passes In this study, statistical evaluation was made accordingly the PM data measured with personal measurement device in Selçuklu District of Konya and the meteorological and the air pollution data provided from air quality monitoring station, which is affiliated by the Ministry of Environment and Urbanization, located nearby. Pearson correlation test has been applied to both data sets and a significant relationship has been detected between the measured and provided data. Moreover, multiple linear regression was applied to the data for PM2.5 and PM10 separately. Adjusted R2 of the analysis has been found as 0.573 and 0.559 respectively for PM2.5 and PM10 which explains almost half of the relationship between PM and meteorological variables. The highest positive effect on PM pollution was determined as air temperature. Finally, principal component analysis (PCA) was applied to both data and 4 different principal components were detected. Measured PM2.5 and PM10, air temperature, and relative humidity were clustered at the same component group.Toz fırtınaları, rüzgârın yönü ve hızı ile ilgili olarak dünyanın birçok ülkesine yayılan ve yılda birkaç kez meydana gelen yaygın olaylardır. Özellikle partikül madde (PM), bu fırtınalarla yayılan ana kirletici maddedir. Toz fırtınaları nedeniyle, toz fırtınası geçişleri yolunda bulunan alanlarda PM konsantrasyonları hızla artmaktadır. Bu çalışmada, istatistiksel değerlendirme Konya'nın Selçuklu ilçesinde ölçülen PM verileri ile yakınlarda bulunan Çevre ve Şehircilik Bakanlığına bağlı hava kalitesi izleme istasyonundan sağlanan meteorolojik ve kirlilik verilerine göre yapılmıştır. Her iki veri setine de Pearson korelasyon testi uygulanmış veriler arasında önemli bir ilişki tespit edilmiştir. Ayrıca, PM2.5 ve PM10 verilerine ayrı ayrı çoklu doğrusal regresyon uygulanmıştır. Regresyon analizinin düzeltilmiş R2'si PM2.5 ve PM10 için sırasıyla 0.573 ve 0.559 olarak bulunmuştur ve bu da PM ile meteorolojik değişkenler arasındaki ilişkinin neredeyse yarısını açıklamaktadır. Hava sıcaklığının, PM kirliliği üzerinde en yüksek pozitif etkiye sahip olduğu bulunmuştur. Son olarak, temel bileşen analizi (PCA) hem ölçülen hem de sağlanan verilere uygulanmış ve 4 farklı ana bileşen tespit edilmiştir. Ölçülen PM2.5 ve PM10, hava sıcaklığı ve bağıl nem aynı bileşen grubunda kümelenmiştir

Prevalence and risk factors of allergies in Turkey: Results of a multicentric cross-sectional study in children

The Prevalence And Risk Factors of Allergies in Turkey (PARFAIT) study was planned to evaluate prevalence and risk factors of asthma and allergic diseases and also to find out which geographical variables and/or climatic conditions play a role determining the prevalence of allergic diseases in Turkish school children. Study was planned as cross-sectional questionnaire-based. About 25,843 questionnaires from 14 centers were appropriate for analysis. Parental history of allergy, having an atopic sibling and other atopic disease in index case was significant risk factors for all allergic diseases. Breast feeding decreased the risk of current asthma (OR: 0.92, CI: 0.86-0.99) and wheezing (OR: 0.93, CI: 0.87-0.99) but not allergic rhinitis and eczema. Respiratory infection in the past was an important risk factor for the occurrence of allergic diseases especially for asthma which was increased 4.53-fold. Children exposed to household smoke were significantly at higher risk of asthma, wheezing, and allergic rhinitis (OR: 1.20, CI: 1.08-1.33; OR: 1.21, CI: 1.09-1.34; and OR: 1.32, CI: 1.21-1.43, respectively). All allergic diseases were increased in those children living in areas which have altitude of below 1000 m and mean yearly atmospheric pressure above 1000 mb. The study has suggested that household and country-specific environmental factors are associated with asthma, wheezing, allergic rhinitis, and eczema risk during childhood in Turkey. © 2007 The Authors
