Planning is an essential part of solid waste management (SWM), a city’s ability to predict the quantities of solid waste is crucial to its medium and long-term solid waste management plans. In this research, a projection of the quantities of Yola’s solid waste for a period of 16 years was made. A corresponding projection of the quantities of greenhouse gases that will be emitted into the atmosphere within that period envisaging three different SWM scenarios was also made using İller Bankası method. The first scenario being the existing practice of open dumping. The second open burning, the third - incineration with electricity recovery. Institute for Global Environmental Strategies simulation tool for greenhouse gas emissions from solid waste management was used for the analysis of the greenhouse gases emissions. It was found that by the end of the 16 years being forecasted, 963,276 tonnes of solid wastes would have been dumped at the dumpsite in the city. The study also found that if this waste accumulated over this 16-year period are to be managed based on the three scenarios envisaged, 337,822tCO2eq, 444,825tCO2eq and 250,461tCO2eq would have been emitted into the atmosphere respectively. The study recommended that reduction in the per capita waste generation of the city should be encouraged. In addition, incineration with energy recovery should be adopted since it is the most environmentally friendly method for managing the huge quantities of solid waste disposed of in the city’s dumpsites.

Energy efficiency in ships has been extensively studied and many applicable solutions have been found in the literature.  The Energy Efficiency Design Index, which aims to reduce the CO2 emissions of ships is valid for international merchant ships of 400 gross tonnage and above and ships with a construction contract on or after January 01, 2013. This implementation became a fast key instrument for the ships to be energy efficient. In this study, the energy efficiency of 21 sea buses operating in Istanbul Strait was analysed. The energy efficiency design index of sea buses was estimated and investigated whether there is a need for optimization in light of EEDI for non-energy efficient ships. Some practical measures have been offered to reduce EEDI value and the harmful effects of CO2 exhaust gas emission.

The rapid increase of the human population and industrialization rate in the globalizing world poses an important risk in terms of air pollution. Air pollution is an especially important issue for public health. Making the accurate predictions for air pollutants is an important step to take necessary measures. In this study, forecasting analysis for the future period was made by using the monthly average concentration values of Particulate Matter (PM2.5) causing air pollution in the Çerkezköy district of Tekirdağ province between January 2017 and April 2020. "Winters’ Method” and “Fourier Analysis with Least Squares Method” were used as the prediction approach. Mean Absolute Error (MAE), Root Mean Square Error (RMSE) and Mean Absolute Percentage Error (MAPE) model performance criteria were calculated based on the predictive values and actual values obtained. Whether the methods with structurally different algorithms differ in terms of prediction success was examined. Using the prediction methods, predictions for the next 20 months for PM2.5 values were obtained. The predictive values obtained from both methods were intended to create a preliminary study value for decision makers and strategists working on air pollution.

Fine atmospheric particles (PM2.5) and coarse particles (PM10), have been reported as major contributors to the low life expectancy of 54 years in Nigeria, the most populous country in Africa. This study was designed to provide baseline data on PM2.5 and PM10  levels in Benin City, wherein traffic control measures have recently been introduced. A light scattering approach (Cel – 712 Microdust Pro Real – time Dust Monitor) was employed for the PM quantification. The average PM2.5 concentration obtained (31.48µgm-3) was found to be higher than the WHO threshold limit (25 µgm-3) by a factor of 1.25. At 60% of the sampling sites, the WHO 50 µgm-3regulatory limit for PM10 was also violated, with a city range of 21.4 – 57.8 µgm-3. Spatial variations in the PM fractions were statistically significant (p&lt;0.05). The source identification and apportionment studies by Principal Component Analysis (PCA) and Multiple Linear Regression (MLR) suggested that motor vehicles were the major source of PM2.5 (77.3%) and PM10 (70%) in the city with the remainder coming from refuse combustion. The average on–road respiratory deposition dose (RDD) rates analysis estimated that 6.96% of the measured PM were deposited in the tracheobronchial region, 12.36% in the alveolar and 78.86% in the head airway of the commuters and pedestrians in the city.

In our paper we have analyzed the quality of drinking water in the rural area of the city of Prizren, rural areas are supplied by forty underground wells of the city. Where the production capacity is around 850 l/sec where about 60% of the city is supplied by pumps, 40% by gravity. The distribution network of drinking water pipes in contrast to the urban area which is from the sixties, in rural areas the distribution network is from the nineties, the composition of the distribution pipes is made of polyethylene materials, the distribution network is always attacked by illegal connections that can be sources of drinking water pollution this has also been the reason that pushed me to do this research. The biggest problem in protecting the quality of groundwater and surface water are industrial discharges, the close presence of stables, communal services, rainfall, outdated distribution network, illegal network connections.The purpose of this paper is for us to know the quality of drinking water in the rural area of the city and from the analysis made it results that the quality of drinking water is 99% in accordance with normal values for drinking water. We checked the water quality in the March 2019 time interval at four sampling sites (Krua) in the rural suburban area of the city.
