This paper deals with the analysis of challenges and perspectives of the transition to electric vehicles as a sustainable solution for the transport sector in the context of global energy challenges and the need to reduce negative environmental impacts. With an emphasis on the energy situation in Bosnia and Herzegovina, the paper explores the possibilities of switching to electric vehicles and analyses the effects of electricity sources on CO2 emissions. The paper highlights the motivation to switch to electric vehicles, driven by the need to reduce greenhouse gas emissions and rely on renewable energy sources. After analyzing relevant studies, it is concluded that smaller and lighter electric vehicles have lower CO2 emissions and that the participation of renewable sources in electricity production reduces these emissions. The conducted analysis of the vehicle fleet specifies that the CO2 emissions of electric vehicles are not zero and that they depend on the source of electricity. Furthermore, other factors, such as the production of batteries, also play an important role in the overall environmental impact. Although the motivation to switch to electric vehicles is emphasized to reduce greenhouse gas emissions and use renewable energy sources, it has been shown that the CO2 emissions of electric vehicles are not zero and that it significantly depends on the source of electricity. This paper acknowledges the presence of emissions associated with battery production, storage, and disposal, as well as with vehicles themselves. However, it does not delve into this issue in detail. Future research will aim to address this matter more thoroughly.

Disinfection byproduct (DBP) formation during water and wastewater treatment is a paramount concern for public health and environmental preservation. Dissolved organic nitrogen (DON) serves as a recognized precursor to DBP formation, which can potentially jeopardize human health. This review article offers a comprehensive insight into DON's influence on DBP formation during water and wastewater treatment processes. It delves into DON's sources, properties, and concentrations in water and wastewater, underlining the variability dependent on water source and environmental conditions. The mechanisms of DBP formation from DON, encompassing formation pathways and influencing factors, are meticulously examined. Different treatment methods, like chlorination, ozonation, and UV disinfection, are carefully examined to see how they affect the formation of DON and DBP. Factors that sway DON's impact on DBP formation are also explored. The review also presents various DBP mitigation techniques, spanning physical, chemical, and biological treatment methods, their efficacy in curtailing DON's influence, and their potential pros and cons. It addresses challenges, outlines future research directions, identifies knowledge gaps, and highlights the necessity for regulatory measures and policies, providing recommendations for prospective research avenues. It is clear from this in-depth review that more research is needed to understand how DON affects the formation of DBP entirely. It is also essential to protect human health and the environment and follow the rules first when treating wastewater. In conclusion, it analyzes DON's part in forming DBP in water and wastewater treatment. This emphasizes the need for ongoing research and mitigation strategies to protect public health and water quality.

Recent innovative research efforts on the usage of plastic wastes as a cheap carbon source for carbon nanotubes (CNTs) production has emerged as a low-cost and sustainable means of producing CNTs. Although, plastic waste derived CNTs are rarely used in some purity-sensitive and high-alignment needed applications due to the poor quality CNTs resulting from the abundance of impurities such as non-crystalline amorphous carbon, metallic nanoparticles and other impurities. Therefore, purification is a crucial issue to be addressed in order to fully harness all potential applications of CNTs derived from waste plastic materials. Here, the effect of employing different purification methods on the morphology and purity of waste plastic derived CNTs were investigated. CNTs was synthesized using waste polypropylene plastic as carbon feedstock via single-stage catalytic chemical vapour deposition technique (CVD). As-produced CNTs were purified using liquid phase oxidation (chemical oxidation in nitric acid), gas phase oxidation in air and a combination of both liquid and gas phase oxidation method. The obtained purified CNTs were characterized for morphology, purity, surface functional groups and crystallinity using Transmission Electron Microscopy (TEM), Raman Spectroscopy, Fourier transform infrared spectroscopy (FTIR), and X-ray powder diffraction (XRD), respectively. Results obtained showed that a combination of both liquid and gas phase oxidation purification technique resulted in purer and better quality CNTs while chemical treatment present more structurally defective CNTs compared to other investigated treatment methods. This study confirms that the choice of purification techniques influences the morphology and quality of plastic derived CNTs.

In this study, first, a list of pesticides that can potentially pose environmental exposure risks was compiled by analyzing the recent literature on residue levels in fresh vegetables produced in Türkiye. Then, by using the fundamental environmental partitioning properties of these pesticides, their potential multi-media environmental distributions were assessed. Acetamiprid, chlorpyrifos, and pyridaben were among the pesticides that frequently exceeded the residual limit values. Multi-media environmental modeling was conducted for these three pesticides using an evaluative four-compartment (air, soil, water, sediment) model. Compartmental distributions, inter-compartmental mass transfer rates, advective, and reactive losses were estimated for the selected pesticides after their simulated application to soil. The ranking of overall persistence among the pesticides was found to be pyridaben > chlorpyrifos > acetamiprid. The percentage mass distribution of acetamiprid in water was higher due to its low volatility and high solubility. The overall persistence of chlorpyrifos was limited by its higher partitioning to air although it is more persistent than pyridaben in other compartments. To investigate the residue dynamics of the three pesticides in tomato crops, temporal changes in harvest fractions were compared using the regression equations of the crop model dynamiCROP. Acetamiprid was estimated to be taken up at higher rates in tomatoes after initial application. The residue dynamics of chlorpyrifos and pyridaben were found to be similar. The quantitative methods in this study can be used to assess the environmental risks associated with commonly used pesticides in Türkiye and to address the issue of exceeding residue limits in agricultural products.

A year-long research was conducted with a novel purpose for categorizing and documents the existing fish diversity and abundance of Bamui beel in Jamalpur district located in Northeast Bangladesh, within a time frame from July 2022 to June 2023. A total of 46 fish species were identified that belong to 18 taxonomical families and 8 orders. The most abundant family was Cyprinidae (25%). Among 46 species, 37% were commonly available (CA) and 11% were abundantly available (AA) in terms of biodiversity status. According to the global conservational status, around 74% were reported as least concerned (LC) whereas 4% were nearly threatened (NT). On the other hand, in consonance with the conservational status of Bangladesh 52% were least concerned (LC) and 11% were endangered (EN). Pielou’s evenness score in Bamui beel was highest (0.247) during pre-monsoon and lowest (0.213) in monsoon. Shannon-Weaver diversity index ranged between 1.992 to 2.114. whereas Simpson’s dominance index value was a maximum of 0.883 in pre-monsoon and a minimum of 0.852 in monsoon. The yearly fish production of the beel was 7.023 metric tons during that year. Besides this, small indigenous species (SIS) of fish dominated with 63.34% of the beel's species makeup.

Climate change has the potential to raise temperatures, alter precipitation patterns, and alter how water resources are distributed globally. The occupancy rates of drinking water supplies may change as a result of these changes. For instance, dwindling water supplies may result from rising temperatures and diminishing precipitation. As a result, the occupancy rates of the reservoirs may drop, making it harder to deliver drinking water. Climate change, however, might highlight regional variations and result in wetter conditions in some places. The occupancy rates in the reservoirs could rise in this scenario. Heavy rains, however, can also result in additional issues like infrastructure damage and floods. Climate change-friendly actions must be taken to manage water supplies in a sustainable manner. In the management of water resources, dams are crucial. It has been observed that when a reliable estimate of a dam's flow is provided, data-based models can produce valuable findings for a variety of hydrological applications. The relationship between climate change and water supplies is better understood thanks to this study.

In this study, spatiotemporal relationship between PM2.5 and PM10 concentrations and meteorological parameters were investigated for Silivri and Umraniye districts in Istanbul for 2014-2020. For this purpose, hourly PM2.5 and PM10 concentrations values of two air quality monitoring stations and meteorological data (wind speed, wind direction, relative humidity, total precipitation, minimum and maximum temperature) were examined. In all seasons, while PM concentrations were lowest at 06:00 local time (LT), PM2.5 and PM10 have peak values around 09:00 and 19:30 LT both in Silivri and Umraniye mainly due to anthropogenic activities such as vehicle exhaust emissions. In daily perspective, highest PM values were observed on Sundays in winter at Silivri. On the other side, peak PM values are shown on Fridays at Umraniye. It was found that local emission sources during low wind speeds cause the highest PM2.5 concentrations during winter months and southerly winds exceeding 8 m/s increase the PM10 levels at Silivri and Umraniye. The statistical analysis showed that PM2.5 and PM10 concentrations at Silivri were negatively correlated with wind speed with correlation coefficients of -0.56 (winter), -0.47 (autumn), respectively. Wind speed is negatively associated with PM2.5 (r=-0.48) and PM10 (r=-0.38) in winter season at Umraniye. In addition to this, relative humidity showed negative relationship with PM10 (r=-0.43) in spring at Silivri, while a positive correlation was found between PM10 (r=0.40) and PM2.5 (r=0.38) measured in the summer season and the maximum temperature. In addition to the anthropogenic factors (e.g. urbanization, transportation, and industrialization) that decrease air quality of Istanbul, local meteorological variables and atmospheric transport of pollution are observed to be the other factors that contribute to air pollution.

During the pandemic period, people have used various personal protective equipment including gloves, facemask and face shields. Among them, disposable facemask play a critical role to control the spread of COVID-19, that situation lead to occurring huge amount waste materials. Hence, there is urgent need to evaluate and suspend such waste materials from environment. Herein, we have investigated the potential use of disposable facemask as oil sorbent material for efficient oil/water separation. Due to their hydrophobic/oleophilic character of PP based disposable facemask. Some structural characterization techniques are employed to examine the facemask. A number of tests including absorbency, oil/water separation stability in oils and waters, selective removal of oils in different water medium have been systematically investigated. The outcomes show that waste facemask have great potential in the field of oil-water separation that achieve selectively separate the oil from oily wastewater.
