“…Özellikle kış dönemlerinde ısınma amaçlı tüketilen doğal gaz, akaryakıt ve kömürden kaynaklı partikül ve kükürt seviyeleri çok yüksek olmaktadır. Fosil türevli enerji sistemlerine kıyasla güneş enerjisi sistemleri olan fotovoltaik sistemler hiç bir şekilde sera gazı emisyonu, hava kalitesini düşüren partikül veya atık yaratmamaktadır [15,16]. Üstelik fotovoltaik sistemlerin kullanım ömürleri bittiğinde kullanılan hammaddeler geri dönüştürülebildiklerinden yaşam döngüleri açısından bakıldığında da sürdürülebilir oldukları görülmektedir.…”

Öz: Günümüzde modern toplumların elektrik enerjisi ihtiyacını karşılamak için kullanılan fosil türevli yakıtlardan hızla doğa dostu olan yenilebilir enerji kaynaklarına geçilmektedir. Fosil türevli yakıtların kullanılması sonucunda biriken sera gazları nedeniyle küresel iklim değişikliği ortaya çıkmıştır. Bunu yanında hava kalitesi de bozulmaya başlamıştır. Güneş enerjisi ekonomik ve teknik uygulanabilirlik açısından en yaygın olarak tercih edilen yenilebilir enerji kaynağı olarak günümüzde kabul görmektedir. Yapılan bu çalışmada Niğde ili için güneş enerjisinin elektrik enerji üretimli potansiyeli, ekonomik ve çevresel olarak uygulanabilirlik açısından incelenmiştir. İldeki mevcut arazi kullanım haritaları, tarım arazileri ve güneş radyasyon potansiyeli haritaları bir arada değerlendirilmiştir. İldeki tarım arazisi ve orman vasfını yitirmiş alanın sadece %3,4 güneş enerjisi üretimi için kullanıldığında gerekli olan elektrik enerjisi ihtiyacı karşılanabileceği hesaplanmıştır. Bu enerji yılda 435924 ton CO2 emisyonun atmosfere verilmeyeceği anlamına gelmektedir.Abstract: Today, fossil-derived fuels are used to meet the electricity needs of modern societies, and quickly switch to environmentally friendly renewable energy sources. As a result of the use of fossil-derived fuels, global climate change has increase due to the accumulation of greenhouse gases. Besides this, the air quality has started to deteriorate. Solar energy is now accepted as the most widely used renewable energy source in terms of economic and technical viability. In this study, solar energy potential for Niğde city province was examined in terms of potential, economic and environmental viability of electrical energy production. Current available land use maps, agricultural landmarks and solar radiation potential maps have been evaluated together. It is calculated that the required electricity energy requirement can be met when the current nonagricultural land and the non-forest land are used for only 3.4% solar energy production. This means that 435924 tons of CO2 emissions per year will not be given to the atmosphere.

“…Therefore, extensive population exposure to that particulate pollution is apparent, risking the overall urban public health standings of the city. Particulate Matter (PM), both coarse (PM 10 -particles diameter ≤ 10 micrometres) and fine (PM 2.5 -particles diameter ≤ 2.5 micrometres) particles, are mainly responsible for respiratory health problems [3][4][5][6][7]. The typical effects of PM exposure include asthma, bronchitis, reduced lung function, cardiovascular disease, and other chronic effects associated with premature mortality [8][9][10][11][12][13][14] when exposed for a longer period.…”

“…Again, prolonged uncontrolled development activities, like the ongoing MRT (Mass Rapid Transit) and BRT (Bus Rapid Transit) constructions that are taking place in Dhaka city, can be responsible for an increased PM (Particulate Matter) level, irrespective of the seasons. Industrial fossil fuel burning (especially diesel and crude oil) throughout the year is another consistent source of PM pollution [3,33], which is sourced from several power plants, cement, fertilizers, steel, pharmaceutical, and garments industries within a 100-km radius of the city [34]. The factors (other than industrial pollution) discussed above might vary depending on time, but the vehicles operated on the road remains similar throughout the year in a city, and this is also the case for Dhaka City.…”

Vehicular PM Emissions and Urban Public Health Sustainability: A Probabilistic Analysis for Dhaka City

Particulate Matter (PM) pollution is generally considered as a prime indicator of urban air quality and is linked to human health hazards. As vehicles are a vital component of an urban setting, the risks of particulate pollution need to be assessed. An emission modelling is essential for that, and thus stochastic modelling approach involving Monte Carlo simulation technique was applied, aiming to reduce the uncertainty in emission modelling. The risks scenarios for the emissions were generated for 2019 (present state) and 2024 (future), integrating the probability of emissions and the associated AQI (Air Quality Index). Despite the vehicles being a minor source of PM in Dhaka (compared to the contribution from other sources), about one-third of the city is found under high risk due to the exhaust particulate pollution; having the potentiality to cover more than 60% of the city in the coming years, affecting the urban public health sustainability. However, the extent of implementation of planning and management strategies can revert the scenarios for the city, which can plausibly reduce the risk from 80% to 50%, or even to a no-risk state.

“…A diesel particle filter (DPF) is a typical example of control technology for on-road diesel vehicles which can greatly reduce BC emissions. Its purification efficiency can be as high as 80% [7,8]. Meanwhile, the DPF method can be easily installed without engine improvement and is widely used throughout the world [9,10].…”

In order to reduce black carbon (BC) emissions from diesel vehicles, a regional atmospheric chemistry model (WRF-Chem) was used to investigate the effects of installing a high-efficiency device for vehicle exhaust control, a diesel particulate filter (DPF), on diesel vehicles in China. To reduce the uncertainty of estimation, three sensitivity experiments were designed and conducted for different emission scenarios. The first experiment uses the standard black carbon emissions of diesel vehicles without engaging in any emission control actions (referred to as CTRL), and the other two experiments were conducted using different DPF devices to reduce BC emissions by 65% (CASE1) and 39% (CASE2), respectively. The results show that the model simulation reasonably represents the measured BC concentrations. The highest BC concentrations occurred in large cities of the North China Plain (NCP) and present important seasonal variations. The results suggest that the reduction in diesel vehicle emissions has great benefits for reducing BC pollution not only in winter but also in other seasons. Sensitivity studies show that in CASE1, the average BC concentrations decreased about ~6% in January and by more than 10% in the other seasons. The greatest reduction exceeded 50%. In CASE2, the average BC concentrations decreased by about ~3.5% in January and by more than 7% in the other seasons. This study suggests that adding DPF to a diesel vehicle can have a significant influence on reducing BC concentrations in China. Thus, this study provides a practical basis by which diesel vehicle emissions can be reduced.
