Transportation sources are a major contributor to air pollution in urban areas. The role of air quality modeling is vital in the formulation of air pollution control and management strategies. Many models have appeared in the literature to estimate near-field ground level concentrations from mobile sources moving on a highway. However, current models do not account explicitly for the effect of wind shear (magnitude) near the ground while computing the ground level concentrations near highways from mobile sources. This study presents an analytical model based on the solution of the convective-diffusion equation by incorporating the wind shear near the ground for gaseous pollutants. The model input includes emission rate, wind speed, wind direction, turbulence, and terrain features. The dispersion coefficients are based on the near field parameterization. The sensitivity of the model to compute ground level concentrations for different inputs is presented for three different downwind distances. In general, the model shows Type III sensitivity (i.e., the errors in the input will show a corresponding change in the computed ground level concentrations) for most of the input variables. However, the model equations should be re-examined for three input variables (wind velocity at the reference height and two variables related to the vertical spread of the plume) to make sure that that the model is valid for computing ground level concentrations.

Abstract This study investigates the relationship between urbanization and air pollution in Turkey. Dynamic ARDL method was used for the period 1960–2014. According to the findings, there is a positive and statistically significant relationship between long-term urbanization and Co2. If urbanization increased by 1%, carbon emissions increased by 0.02%. There is a similar relationship between the shocks that will occur in population growth and Co2 emission in the long term. However, there is a negative and statistically insignificant relationship between the two variables. In the relationship between GDP and Co2, there is a positive relationship in the long term. GDP increase of 1% increases Co2 emissions by 0.11%. There is a similar relationship between long-term GDP shocks and Co2 emissions. According to short-term analysis results, energy consumption increases Co2 emissions by the same rate as GDP. However, the astonishing result of the study emerges here. Empirical results show that a long-term positive shock in energy consumption reduces CO2 emissions and a negative shock increases pollution. According to these results, Turkey has not reached the point of sustainable growth. For this reason, this developing country needs to make regulatory implementations and determine future policies for these impacts affecting air pollution.

Capping greenhouse gas emissions and reducing air pollution on the farm challenges the place of the diesel tractor in future sustainable vineyards. Tractors are responsible for the largest share of all CO2 emissions at vineyard plot scale, mostly resulting from pest and disease management and soil maintenance (Adoir et al., 2019). Electric vehicles will thus be required to meet climate change reduction goals. In this article, the characteristics of battery and hydrogen electric tractors are compared, and their potential in the grapevine growing sector is assessed.

Atmospheric air pollution is one of the main factors, which negatively affects the health of children in Ukraine. It can exacerbate chronic diseases and decrease the quality of life of children and their families. The aim to determine the correlation ranking between the incidence and prevalence of diseases among children in Ukraine in 2015 and the volume of pollutant emissions from stationary and mobile sources of pollution per person depending on the area of residence. Materials and methods. During the analysis, data from the Center for Medical Statistics of the Ministry of Health of Ukraine and the State Statistics Service of Ukraine for 2015 were used. Methods of system approach, epidemiological, correlation and cluster analysis are applied. Results. In our study we have discovered that the volume of pollutant emissions from stationary and mobile sources into the atmosphere per 1 person had a direct impact on the incidence of all diseases of children in Ukraine, especially children aged 0–6 years (p<0.01). The closest direct correlation was observed between pollutant emissions and prevalence of respiratory diseases among children, especially in children aged 0–6 years and 15–17 years and with the prevalence of bronchial asthma and diabetes in all age groups. The correlation between children morbidity level of tuberculosis, some infectious and parasitic diseases, congenital anomalies, circulatory and digestive diseases, diseases of the musculoskeletal system, ear and mammary gland and the volume of air toxic emissions haven't reached any important statistical significance. Correlation between the mortality rates of children under one year and the incidence of all diseases, including respiratory diseases, some infectious diseases, acute respiratory viral infections, pneumonia and influenza, cerebral palsy and air toxic emissions also haven't reached statistical significance. Conclusions. Morbidity and prevalence of all children's diseases was chained in different manner with the amount of pollutant air emissions. This fact indicates that the increase in morbidity is associated not only with socio-economic and medical and genetic factors, but also with environmental influence. This situation requires brings a necessity of establishment the issue of environmental safety of the population of Ukraine, especially children. No conflict of interest were declared by the authors. Key words: children, morbidity, prevalence, mortality, air pollution.

This contribution deals with the manipulation of NOX emissions from Volkswagen diesel cars on the one hand, and with the manipulation of CO2 emissions from diesel and petrol cars by Volkswagen on the other. The scandal became public in 2015. Volkswagen is a German car manufacturer; to the company also belong Porsche, Audi, Skoda, Scania, Ducati, Seat, Bentley, Bugatti, Lamborghini and Quattro.
