Evaluation of water contamination in a crossborder river catchment affected by mining activities (a case study between Republics of Serbia and Bulgaria)

1,

Abstract: The current article aims to evaluate water contamination in the crossborder section of the Timok River in terms of metalloids and heavy metals. Water pollution comes due to the unregulated discharges of untreated effluents from the Bor mining area (Eastern Serbia) and surrounding ore-smelting plants, dressing and processing factories. Input data includes information concerning the values of eight chemical parameters (As, Cd, Cu, Fe, Mn, Ni, Pb, and Zn), measured at one water sampling site from 2015 until 2020. The analysis follows the Environmental Quality Standards (EQS) for priority substances and some other pollutants recommended in Directive 2013/39/EC and their equivalent criteria transposed into Ordinance H-4/2012. The Heavy Metal Pollution Indеx (HPI) to assess the suitability of water resources for various human needs is calculated. Results obtained show the content of Cd, Cu, Fe, Mn, Ni, and Zn does not fulfill the EQS. The contamination with Cd and Cu is the most severe, the highest concentrations exceeding the normatively determined standards by more than 20 times. The HPI achieves scores ranging from 200.58 (2015) up to 1163.65 (2019), indicating “High pollution” and suggesting the water resources are inappropriate for human consumption. This work complements past studies with findings for a recent period.

Solid waste management practices in an indigenous Nigerian city: a case of Alesinloye in Ibadan

1,, 2

Abstract: Solid waste management (SWM) is an essential urban service in every human settlement. Despite its importance, cities globally struggle to guarantee its provision even in developed countries. This study examines SWM practices in Alesinloye, Ibadan, Nigeria. A structured questionnaire prepared with KoboCollect was used to interview 182 households using a convenience sampling technique. Findings revealed that households are predominantly married youth with formal education and largely from the Yoruba ethnic group. It further established that food constitutes the leading solid waste component in households. The food waste, along with other waste materials generated, was disposed of mixed because there is no waste sorting system. The households mainly adopt unhygienic and unsustainable approaches such as disposable polythene bags and open space to store solid waste generated temporarily. The private waste firm was primarily responsible for solid waste collection using door-to-door (kerbside) methods in providing its service. The solid waste collection is mostly executed weekly, and the majority of the households consider it suitable. The households paid users’ charges of between ₦500 ($1.09) and ₦ 2000 ($4.35) monthly, and the variations were attributed to mainly waste quantity. While 75.2% of the households expressed satisfaction with users’ charges on solid waste services, 78.6% were unwilling to pay more for improved services, thus indicating the value placed on environmental quality. Finally, the study recommends the establishment of a SWM system towards zero waste community; the establishment of a waste management committee to serve as environmental stewards; the intensification of public campaigns and awareness of the importance of sustainable SWM, and the resuscitation of the Alesinloye recycling plant.

Environmental potential of Aedes Aegypti Mosquitoes for Dengue haemorrhagic fever in Pekanbaru, Indonesia

1,, 2, 2, 2, 2, 3, 4

Abstract: Dengue fever is frequently considered a common fever, and this misconception carries the highest risk of fatality. Dengue haemorrhagic fever is still one of Riau Province’s unsolved diseases. This is one of the reasons why this study is necessary to identify prospective mosquito environmental zones with major significance for understanding epidemic transmission in the Pekanbaru City area. The bivariate statistical approach was employed in this research. The aim is to link environmental physical factors to data on the occurrence of dengue haemorrhagic fever in Pekanbaru City. The area under the curve for the correlation between the environment and the distribution of dengue haemorrhagic fever was 0.76 for the rainfall parameter, with 0.68 for the area under the curve derived from the air humidity parameter. The establishment of six environmental indicators resulted in a weight of evidence value of 10,467 to -35,693 for the mosquito’s environmental potential. Meanwhile, the most favourable potential zone, which encompasses 5,935 ha, accounts for 9.18% of the overall area. Areas with the highest risk of spreading Aedes aegypti mosquitoes were found around the city center, both residential and office areas. The risk of dengue haemorrhagic fever transmission in this zone is higher than in the other three zones. By taking earlier events into account, this knowledge can be one of the early preventions in understanding the environmental structure of the Aedes aegypti mosquito habitat.

Protected areas as recreational zones for nearby cities – the case study of the city of Vršac

1,, 1

Abstract: The fast-paced life has led many people to practise more frequent and shorter trips to nature. City dwellers are particularly inclined to this. Protected areas (PAs), especially those in the vicinity of cities, provide a good opportunity for one-day excursions and nature-based recreation. The paper presents the results of research aimed at determining how many city dwellers in Serbia use the surrounding PAs for this kind of activities. On a random sample of 247 residents of the City of Vršac above the age of 15, the survey method, with the help of the Statistical Package for the Social Sciences (descriptive statistics, Chi-Square Test and Kruskal-Wallis Test), confirmed the research hypothesis that the utilization of these areas for recreation purposes was insufficient. Based on this and four additional hypotheses that were tested, conclusions are drawn that will serve to define guidelines for the development of excursion tourism in the studied areas and enrich the scarce local scholarly literature on the utilization of PAs for recreation by the urban population.

The changing river course and its impact on riverine society: A case study on the Padma River, Murshidabad District, West Bengal (India)

1,

Abstract: River bank erosion within Murshidabad district is a tragedy, which happens haphazardly along the bank of the Padma River system. The main objective of the study is to analyze the changing river course and its impact on society. By comparing the toposheet and Landsat (5 and 8) images of the Padma River of the Murshidabad district from the years 1924, 1990, and 2020, it is clearly observed that there have been significant changes on the southern portion of the river since 1924 (Bhagawangola II, Raninagar II, and Jalangi Block), while less changes occur on the central part of the river, which is near the Lalgola block. But in the year 2020 significant changes have been found in the northern and middle portion of the district near Samserganj and Lalgola block. Those parts belong to a highly vulnerable zone of bank erosion. This study analyzed some factors, such as soil stratification of the river bank and human encroachment as an obstruction to the natural river flow, also responsible for bank failure. The river has been consuming the vast portions of the right bank every year due to its increasing sinuosity. The victims are mostly in the Samserganj, Lalgola, Bhagawangola II, Raninagar II and Jalangi blocks, who suffered greatly from 1924 to 2020 due to moving of river course by 27% on the right side, which is notified from cross sectional analysis. Additionally, the predicted erosional impact of the region highlights the socio-economic perspective of the research area.
