The environmental crisis is seen in the indiscriminate disposing of refuse by staff and students, the poor maintenance culture of the toilet environment in the students’ hostel, the pollution of the air caused by the burning of refuse by staff in residential areas, and the indiscriminate urination and defecation in some parts of the university by students and visitors. This study adopted content analysis. The findings reveal that this has an immense impact on the physical, psychological, and mental state of members of the university community. Having observed this anomaly, this research proposes that Genesis 1:26 serves as a formidable solution to this escalating crisis. This Biblical pericope calls on man to maintain diligence and discipline in managing and maintaining the environment. It is believed that the solutions given will strongly speak to the increasing environmental crisis in the University of Nigeria, Nsukka.","PeriodicalId":20363,"journal":{"name":"Polish Journal of Environmental Studies","volume":"36 4","pages":""},"PeriodicalIF":1.8,"publicationDate":"2023-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138949865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By constructing an index system for new urbanization and ecological environment, and utilizing a coupled coordination degree model, the coupled coordination degrees of new urbanization and ecological environment were calculated for 31 provinces and municipalities in China. Subsequently, the spatio-temporal evolution characteristics and driving factors of the coupled coordination levels between the two systems were analyzed using non-parametric kernel density estimation and geographic detector models. The results indicate the following: (1) The overall coupled coordination degree of the two systems in the country transformed from a mildly imbalanced state to a barely coordinated state. The coupled coordination degrees of the two systems exhibit a “east-central-west” descending distribution pattern across the three major regions, with distinct temporal and internal differences. (2) The overall, eastern, and central regions show a decreasing trend in the improvement rate and imbalance level of the coupled coordination, while the western region exhibits an increasing trend in both improvement rate and imbalance level. The phenomenon of regional divergence between the eastern and western regions is evident. (3) Economic development, social security, technological innovation, industrial structure, market environment, government capacity, and openness to the outside world have significant influences on the coupled coordination of the two systems.

Plants of W. trilobata were grown in a greenhouse, and treatments were given for two months . Growth parameters of 60 plants were used to build a numerical model. The neural network model was built using Quasi-Newton approaches that containing Broyden-fletcher-goldfarb-shanno gradient (BFGS) learning algorithm, multilayer perceptron (MLP) training algorithm and sigmoid axon transfer function along with 10 neurons at the input network, 9 neurons in the hidden layer, and 1 neuron in the output layer (10-9-1). The selection and validation of the best predictor model were based on lower values of errors and higher value of R 2 . The selected model had a higher values of R 2 = 0.90 and lower values of errors i.e (relative approximate error, RAE = 0.004, root mean square error, RMS = 0.027, mean absolute error, MAE = 0.004, mean absolute percentage error, MAPE = 0.013). Moreover, the highest rank 1 was obtained for leaf area during sensitivity analysis followed by water potential and photosynthesis ranked 2 rd and 3 th , respectively.

It is also drought resistant, which increases its future potential under the ongoing climate change. Moreover, perennial wheat offers and effective strategy for carbon sequestration through increasing soil carbon stocks. However, the effect of perennial wheat on soil properties remains uncertain in the conditions of south-eastern Kazakhstan due to the lack of data. To fill this gap, we conducted a study in which five varieties of perennial wheat were grown in the Almaty region in soils of different fertility for two years. As a result, in the plot where topsoil was removed to a depth of 25 cm, total carbon increased by nearly three times, from 0.54% to 1.42%, and the number of microorganisms increased from 715.1x103±0.2x103 to 48.0x103±0.6x103 colony forming units per ml of soil. The photosynthetic performance of perennial wheat varieties in the experimental plot was not negatively affected by the removal of top soil suggesting that perennial wheat can successfully restore soil fertility and replenish soil with chemical elements involved in photosynthesis. Our results confirm that in the conditions of the south-eastern Kazakhstan perennial wheat makes a significant contribution to the soil carbon stock accumulation and development of soil biota; in our study, these effects were particularly strong in the case of degraded soil.","PeriodicalId":20363,"journal":{"name":"Polish Journal of Environmental Studies","volume":"120 12","pages":""},"PeriodicalIF":1.8,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138959027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The problem of air pollution has become the focus of public opinion and academic research in recent years. This article departs from the traditional single-scale approach and adopts a spatial multiscale perspective. Leveraging annual average PM 2.5 concentration data and urban socioeconomic data spanning the period from 2009 to 2018, in conjunction with atmospheric PM 2.5 remote sensing inversion datasets, a comprehensive analysis is conducted. This analysis encompasses the utilization of GIS spatial-temporal analysis techniques and geographic detectors. The primary objective of this research is to investigate the spatiotemporal evolution characteristics of PM 2.5 in the Yangtze River Basin during the years 2009 to 2018, as well as to elucidate the influencing factors therein. This study is crucial to the joint prevention and control of air pollution. The Results showed that (1) The overall trend in the number of cities with annual average PM 2.5 concentrations below 35 μg/m³ (the annual limit value in China) exhibits fluctuating upward dynamics. (2) From 2009 to 2018, the low-value area distribution of the annual average PM 2.5 concentration in the Yangtze River Basin was stable, whereas the high-value area showed a trend of “first decreasing, then increasing, and then decreasing.” (3) The spatial and temporal agglomeration effect was evident, showing an “east-hot, west-cold” agglomeration pattern. From 2009 to 2018, the high-value aggregation area expanded to the middle part of the Yangtze River Basin and then continued to the north. The low-value concentration area was concentrated in the western part of the Yangtze River Basin, and the range change trend was not large. (4) While each variable concurrently engages in interactions, they also exhibit varying degrees of influence on the spatiotemporal distribution of PM 2.5 . Among them, population density and the proportion of urban built-up areas in the index layer of population and urbanization are strongly correlated factors.","PeriodicalId":20363,"journal":{"name":"Polish Journal of Environmental Studies","volume":" 0","pages":""},"PeriodicalIF":1.8,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138961764","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Then redundancy analysis was used to analyze the influence of climate factors on soil properties. The results showed that: 1) Compared to 1982, the soil properties of Fanjian Mountain changed significantly in 2014. The soil texture evolved from a silty loam in 1982 to a silty clay loam in 2014. There was a significant increase in soil clay particles. In addition, the soil showed acidification, weakened cation exchange capacity, and relatively stable soil total nitrogen but significant loss of soil organic matter and total phosphorus nutrients. 2) In the past 32 years, the environmental climate of Fanjing Mountain has shown the characteristics of increasing annual average temperature and annual rainfall, frequent extreme temperature, widening the annual temperature range and decreasing annual relative humidity. 3) Soil type and maximum annual temperature have a highly significant effect on the evolution of soil properties, while annual rainfall and slope orientation significantly affect the evolution.","PeriodicalId":20363,"journal":{"name":"Polish Journal of Environmental Studies","volume":" 1123","pages":""},"PeriodicalIF":1.8,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138960221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results of XRD shows that there are various minerals in coal gangue, with obvious diffraction peak characteristics, and the minerals with higher levels are quartz, kaolinite, dolomite and potassium feldspar. The trace elements are predominantly found in the residual state. The results of I geo reveal that all trace elements are in a pollution-free state. The potential ecological risk level of Cd belongs to strong risk, while the level of the other elements is slight risk. The result of RAC indicates that the active forms of Mn may cause the greatest harm to the ecological environment, and which deserves further attention.

The findings reveal that higher ESG performance leads to lower debt financing costs. Furthermore, the analysis of mechanisms indicates that the green innovation behavior of enterprises enhances the impact of ESG performance on debt financing costs. Heterogeneity analysis demonstrates that the ESG performance of heavily polluting enterprises in central China has a more significant influence on debt financing costs. For non-state-owned heavily polluting enterprises, the relationship between standard audit opinions is substantial, as audit opinions contain sufficient information and risk disclosure. This study contributes to our understanding of the economic implications of ESG performance and provides valuable evidence supporting enterprises in their efforts to improve ESG performance.","PeriodicalId":20363,"journal":{"name":"Polish Journal of Environmental Studies","volume":" 1099","pages":""},"PeriodicalIF":1.8,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138960246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed that most of chemical characteristics such as pH, total carbon, total nitrogen, total phosphorus and available phosphorus in rhizosphere soils were higher than that in non-rhizosphere soils significantly. The main factors affecting soil bacterial and fungal community structure are soil pH and available phosphorus (bacteria) and available nitrogen (fungi), respectively. Significant difference in the number of biomaker between rhizosphere and non-rhizosphere soils was detected for fungal, but not for bacteria. On contrast, significant difference of the diversity indexes between rhizosphere and non-rhizosphere soils were detected for bacteria, but not for fungi. These differences between rhizosphere and non-rhizosphere soils, and also between bacteria and fungi might caused by roots physiological metabolism of J. mandshurica . The dominant microbial groups are Actinobacteriota, Proteobacteria and Acidobacteriota (bacteria) and Ascomycota (fungi), which accounted for about 80% of relative abundance of bacteria or fungi.
