The protection of plants from diseases is mainly based on the use of chemical pesticides against pathogenic agents of fungal or bacterial etiology. That is why, in the past two decades, much attention has been paid to the development of ecological biological methods of combating plant diseases, which are considered an alternative to the traditional use of chemical pesticides. The aquatic environment is a good source for the detection of new strains of antagonistic microorganisms in relation to phytopathogens. The aim of the research was to determine the potential of the biodiversity of the microbiota isolated from the aquatic environment to combat the development of phytopathogenic fungi. Among actinobacteria, maximal inhibition of test cultures was achieved by strains of the genera Streptomyces (against A. alternata ), Micromonospora (against A. niger ), Actinoplanes, and Nocardia (against F. oxysporum ). Bacteria of the genera Bacillus and Micrococcus possess the highest activity against A. alternata , B. cinerea , and F. oxysporum . The highest activity against phytopathogenic fungi was achieved by micromycetes of the genus Trichoderma (growth inhibition zones reached 40.0 mm). Cyanobacteria Oscillatoria brevis and Oscillatoria acutissima are active against A. niger and F. oxysporum , respectively. As a result, strains that were promising for use in phytosanitary control were discovered.

Levofloxacin, as a typical fluoroquinolone antibiotic, is widely used in human bacterial infection treatment and animal husbandry. However, conventional treatment technologies (e.g., precipitation, coagulation, and microbial metabolism) have limited ability to remove levofloxacin from wastewater. In this work, Fenton oxidation combined with ultrasonic treatment was investigated to efficiently remove levofloxacin from water. As a result, the optimal conditions for Fenton oxidation were first determined by the design of an orthogonal experiment. Then the combined effect of Fenton oxidation and ultrasonic treatment demonstrated a positive synergistic effect. In terms of the sequence selection of Fenton oxidation and ultrasonic treatment, Fenton–ultrasonic (10 min)–interval (40 min) was the best process. Finally, a total of 12 intermediates of levofloxacin were identified via HPLC-MS spectra, and possible degradation pathways were tentatively inferred. In addition, the toxicities of the intermediates were estimated using the Toxicity Estimation Software Tool according to the U.S. EPA proposed standards, and the results suggest that the overall toxicities of the intermediates were relatively alleviated in comparison with levofloxacin. This study provides a strategy for improving the degradation of levofloxacin via Fenton oxidation combined with ultrasonic treatment with a positive synergistic effect in water.

In this study, concentrations of Fe, Zn, As, Cd, Hg, Pb, and Cu in blood and muscle samples and maternal transfer of these elements to eggs and hatchlings were investigated for hawksbill turtles on Ommolgorm, Nakhiloo, and Kharko Islands from the Persian Gulf. The results indicate a significant difference (p≤0.05) between the accumulations of the elements between the rookeries. On three islands, the highest and lowest concentrations of Fe were observed in the yolk and albumin, respectively. The highest concentrations of Zn were found in yolk and maternal muscle from Ommolgorm and Nakhiloo islands, and the lowest concentration of Zn was found in hatchling and abnormal albumin at Kharko Island. The highest amount of As was present in maternal blood, and the lowest was in an abnormal egg on three islands. The highest amount of Hg was in maternal blood and muscle, and the lowest was in normal and abnormal eggs. The highest Pb concentration was in yolk and the lowest was in maternal muscle and blood in Ommolgorm and Nakhiloo Island; however, at Kharko Island, the highest and lowest concentrations were in yolk and normal albumin, respectively. Cd and Cu were ND in the most tissues. Fe, As, Hg, and Pb were higher than Cd and Cu in the maternal blood. The accumulation of heavy metals in the yolk, blood, and hatchling was higher than in other tissues. The accumulation of some elements in samples from Kharko Island was higher than on the other two islands. Based on the results, a significant relationship was found among the concentrations of elements in the maternal blood, yolk, and hatchling tissue. Our results showed a positive correlation between the concentrations in the maternal blood and yolk and hatchling tissue, which confirms maternal transfer of the elements.

This study investigates the relationship between board independence, CEO power, and environmental, social, and corporate governance (ESG) performance of Chinese companies. The study finds that in industrial firms with significant environmental concerns, board independence fails to moderate the adverse effects of strong CEO power on ESG performance. This failure is attributed to management’s excessive focus on short-term profits and lack of checks and balances. However, in non-industrial companies, the positive effect of CEO power on ESG performance can be dampened by board independence. This heterogeneity also varies among companies with different political backgrounds. Moreover, the study emphasizes the significance of potential trade-offs between short-term financial benefits and long-term sustainability objectives across regions and corporate governance methodologies.

With the rise of China’s economy and the expansion of China’s foreign trade scale, the carbon emissions generated by China’s trade are attracting extensive attention from political and academic circles. In the context of global ‘decarbonization’, this paper focuses on the new trade model of digital trade and uses China's provincial panel data from 2013 to 2021 to deeply explore the effect of digital trade development on carbon emissions and its transmission mechanism. We find that digital trade development can reduce regional carbon emissions through structural and technological effects; specifically, industrial structure upgrading, consumption upgrading, and green technology innovation play a crucial intermediary role in this process. Subsequent investigation reveals a non-linear, diminishing trend in the marginal impact of digital trade on emission reduction. Furthermore, once digital trade surpasses the threshold of environmental regulation its marginal effect on emission reduction becomes more pronounced. Additionally, employing a spatial econometric model has revealed that the advancement of digital trade can also contribute to reducing carbon emissions in neighboring regions. Heterogeneity analysis results demonstrate that the eastern region exhibits the most significant emission reduction effect in relation to digital trade, followed by the western and central regions.

The process of urbanization leads to the reallocation and adjustment of agricultural production factors, which has a significant impact on agricultural carbon emissions (ACEs). Based on the panel data of 30 provinces in China from 2007 to 2019, this study explores the mechanism of how urbanization affects ACEs and conducts empirical tests. The results show that there is an “inverted U-shaped” relationship between urbanization and ACEs, with ACEs first increasing and then decreasing as the urbanization rate increases. From the perspective of intermediate mechanisms, urbanization mainly influences ACEs through the scale of farmland operations, the structure of crops, and the intensity of agricultural mechanization. Agricultural land management scale and crop structure have an inhibitory effect on ACEs, but the increasing intensity of agricultural mechanization exacerbates ACEs. In terms of regional heterogeneity, due to differences in physical geography and agricultural policies, the impact of urbanization on ACEs occurs in northern areas and non-major grain-producing areas. The spatial analysis indicates that urbanization has a spatial spillover effect on ACEs in the neighboring provinces. This study contributes to the existing ACEs’ literature by integrating urbanization, agricultural land use, and ACEs into the same theoretical analytical framework, exploring the underlying mechanisms, spillover effects, and regional heterogeneity.

The rapid and unpredictable expansion of urban areas poses a major challenge to humanity in adapting to climate change in the coming decades. Therefore, the presence of urban forests promotes climate change adaptation through their geographic location in cities. This systematic literature review (SLR) analyzed the existing research on ecosystem services provided by urban forests for climate change adaptation. The bibliographic databases Web of Science and Scopus were used for the study according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement. There were 484 publications found that were published between 2011 and 2021 using specific terms in both search engines. However, there were only 59 articles from 26 different countries that met the inclusion criteria. When analyzing these 59 articles, the majority focused on carbon storage, while less than a quarter examined other services such as climate regulation and air purification. Hence,

This paper studies the impact of geomorphic and topographic evolution on environmental planning so as to lay the foundation for future rural environmental planning in Jinan. This paper analyzes the impact of landform evolution on environmental planning and introduces the types of spring rural settlements in hilly landforms and intermountain plains, respectively. On this basis, an artificial neural network is used to reflect the dynamic change law of spring water and is combined with a fuzzy evaluation method to evaluate the impact of underground space development in Jinan on spring water and human activities. Through empirical analysis, it is known that artificial neural networks can accurately detect the dynamic change law of spring water, and on this basis, fuzzy evaluation methods are used to design the impact of spring water-rural settlement landscape planning. The impact of spatial development on spring water is divided into four levels: the stronger impact area, the strong impact area, the general impact area, and the small impact area of underground space development on spring water, which account for about 1.036%, 1.001%, 0.371%, and 97.591% of the total area of the study area, respectively.

Agricultural productive services are fundamental in transforming the paradigm of agricultural development and exert a significant impact on farmers’ behavior in managing their arable land. This paper employs the slack-based measure of the super-efficiency model, known as the Super-SBM model, incorporating unexpected output to gauge the eco-efficiency of cultivated land use (ECLU). Utilizing panel data from Hunan Province spanning the years 2007 to 2020, this study unveils the following key findings: (1) Across various quantile levels, agricultural productive services exhibit a substantial capacity to enhance ECLU, with coefficients ranging from 0.070 to 0.156. (2) The impact of agricultural productive services on ECLU is constrained by both farmers’ income levels and the scale of cultivated land, revealing a dual threshold effect. As income levels rise, the corresponding coefficient increases progressively, from 0.0771 to 0.1147, and ultimately to 0.1571. Similarly, with the expansion of cultivated land, the coefficient increases from 0.1152 to 0.1443, and ultimately peaks at 0.1694. (3) The enhancement of ECLU through agricultural productive services is achieved by reducing the input of environmental factors and mitigating undesirable outputs. (4) Agricultural productive services indirectly facilitate labor transfer, accounting for 10.8% of the overall effect. Consequently, it is imperative to continually enhance the agricultural socialized service system, bolster financial support, and implement policies that foster the development of agricultural productive services to realize sustainable cultivated land utilization.
