Despite the wider success of MARPOL compliance by most of the maritime nations, Bangladesh is still falling behind. According to the literature, vessel pollution in Bangladesh’s ports and adjacent marine areas is still a frequent occurrence. Consequently, the purpose of the study was to determine key challenges and relevant issues relating to MARPOL in the port areas of Bangladesh. Efforts have been made to identify the compliance parameters of MARPOL to address its current state in the Bangladeshi port areas and put forward strategies to get the optimum output. This study uses a mixed approach by collecting data from both primary and secondary sources. Primary data were collected through field surveys from port officials, shipping personnel, academicians, and regulatory authorities using structured questionnaires. Secondary data sources include published books, documents, legislation, and articles, as well as Internet sources. The result revealed that Bangladeshi ports are unable to comply with the entire MARPOL Convention due to lack of commitment, legislation, and resources. Additionally, it assessed the current state of the MARPOL convention and the regulatory framework governing maritime pollution issues. The fundamental causes include an absence of a legal framework and distinct authority, a scarcity of resources, and crew negligence. Therefore, the study proposed adopting new regulations to establish compensation for MARPOL violations, coordination among government agencies, improving resource and monitoring systems.</p></div>","PeriodicalId":544,"journal":{"name":"Environmental Monitoring and Assessment","volume":"197 4","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143698621","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}

Focusing on rice, tea and mustard—three of the state’s most important crops—this research analyses data from 2000 to 2022 using multiple linear regression (MLR) to evaluate the relationship between climatic factors and crop yields. The results show that for every 1 °C increase in temperature, rice yields decline by approximately 0.112 tons/ha (<i>p</i> = 0.002, <i>R</i>² = 0.62), while tea and mustard yields decrease by 0.087 tons/ha (<i>p</i> = 0.005, <i>R</i>² = 0.54) and 0.095 tons/ha (<i>p</i> = 0.003, <i>R</i>² = 0.48), respectively. Rainfall positively influences yields up to optimal thresholds—280 mm for rice, 260 mm for tea and 210 mm for mustard—beyond which excess rainfall leads to reduced productivity, notably in rice due to waterlogging. These findings underscore the high vulnerability of Assam’s rain-fed agriculture to climatic variability and stress the urgent need for adaptive measures. Policy recommendations include developing and disseminating heat- and drought-resistant crop varieties, expanding irrigation infrastructure and adopting precision farming technologies and implementing crop insurance schemes to buffer farmers against climatic risks. By integrating climatic, agronomic and socio-economic factors, this study not only fills gaps in the existing literature but also offers actionable insights for policymakers and stakeholders in Assam and other climate-sensitive regions.</p></div>","PeriodicalId":544,"journal":{"name":"Environmental Monitoring and Assessment","volume":"197 4","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143707151","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}

Findings revealed an annual increase in mining activities at a change rate of 12.3% between 2018 and 2023, with significant vegetation conversion in the Atewa landscape. Mining exhibited a more irregular pattern in the forest reserve, with a rate of change of − 21.4%. The buffer analysis showed that a significant portion of mining occurred within 100 m of river channels, with at least 49.7% of the mined area annually falling within this zone. The buffer analysis also indicated that at least 0.7% of mining activities in the landscape were within the 100 m buffer around the ARFR.

However, the etiology of this disease is poorly understood. In this study, we conducted multi-year monitoring to examine the presence of LCM and BLD symptoms across Ohio, including both symptomatic and asymptomatic forest stands. We collected buds each spring before leaf-out and used molecular methods to detect the presence of LCM. Symptomatic sites had a high proportion of buds colonized by LCM across all sampling years. Detection of LCM DNA in asymptomatic forest stands was largely inconsistent across years; however, its presence overall was a significant predictor of BLD symptoms developing in the county surrounding our sampling site in the following years. LCM DNA was also detected on both <i>Acer </i>sp. and <i>Quercus </i>sp. buds, but detection frequency was low. We found significant correlations between the proportion of buds infested with LCM and the forest basal area consisting of <i>F. grandifolia</i>, suggesting it is the host for this nematode.

Here, an adsorbent was designed to achieve efficient, stable, and recyclable removal of cesium ion contamination, and its adsorption properties were studied in detail. Prussian blue, a promising adsorbent for radioactive wastewater purification, has been often hindered in application due to its small size and easy agglomeration. To address this issue, the luffa fiber with a large specific surface area was employed to form networks loading Prussian blue particles and enhance adsorption capacity. In this paper, the recyclable Prussian blue/luffa was prepared by an in situ synthesis approach. Means such as XRD, SEM, EDS, FTIR, and XPS were applied to characterize its morphology and physicochemical properties. It exhibited outstanding selective removal efficiency for Cs⁺ ions and the ability to be rapidly separated from wastewater. The equilibrium and adsorption kinetics followed the Langmuir isotherm and pseudo-second-order model with a maximum adsorption capacity of 102.01 mg/g. Both pH and temperature had effects on the adsorption performance. The removal efficiency of Cs⁺ by Prussian blue/luffa still retained 71.2% after the 3-cycle test, and the possible mechanism was ion caging and ion exchange. In addition, the presence of co-existing ions only reduced the removal rate by less than 10.0%. Importantly, phytotoxicity assessment is urgently needed to address the adverse effects of applied nanoparticle composites on environmental and human safety. The phytotoxicity assessment was investigated, and the results indicated that the composite had no obvious biotoxicity. It is expected to be a highly potential material for disposing of radioactive wastewater. Future applications may extend to the treatment of various types of radioactive waste, providing a sustainable and effective solution to the field of nuclear waste management.</p></div>","PeriodicalId":544,"journal":{"name":"Environmental Monitoring and Assessment","volume":"197 4","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10661-025-13791-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143707176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The nutritional profile of the phytocompounds found in fruits has been in high demand in pharmaceutics. Due to a lack of sustainable harvesting practices, the species population has been severely fragmented, leading to its limited genetic resources being vulnerable to the threat of climate change. This study was conducted in the northeastern states of India for 2 years between 2022 and 2024 to assess the regeneration fitness of <i>G. pedunculata</i> through sporadic population surveys and to predict its habitat suitability under current and future climatic scenarios using ecological niche modeling (ENM). The study incorporated 19 bioclimatic variables from WorldClim, along with physiographic (elevation, slope, hillshade), edaphic (soil pH, soil organic carbon), and biotic factors (land use, land cover). Species distribution was modelled using an ensemble of four machine learning algorithms—maxent, random forest, support vector machine, and boosted regression tree. Annual precipitation, precipitation of the coldest quarter, soil pH, and precipitation in the driest month were found to have the maximum contributions as key determinants of the species distribution. The ENM predictions of a substantial decline in suitable niches for the species toward projected climatic regimes in the year 2080 with significant model support (AUC = 0.96 and TSS = 0.87), and poor regeneration fitness of the species indicated an alarming situation for the conservation of the species and the development of its sustainable harvesting practices.

This paper aims to validate if thermokarst lakes can be treated as geoindicators of permafrost degradation after wildfires. We analyzed changes in the spatial extent of the thermokarst lakes after wildfires at the part of the Mackenzie River watershed. For that purpose, we examined changes in thermokarst lakes in five test areas before the fire, short and long term after fires, and compared the results with similar unburned areas. Our findings indicate that lake responses to wildfires vary significantly, with no consistent area increase or decrease pattern. However, burned areas exhibit greater variability in lake size compared to unburned sites, suggesting that wildfire disturbances create a state of geoecological disharmony. Long-term reductions in the lakes area point to permanent permafrost degradation, while some lakes expanded, likely due to thermokarst processes. Our results emphasize the potential of thermokarst lakes as indicators of post-fire permafrost changes, reinforcing the need for further research to develop quantitative methods for assessing permafrost degradation in wildfire-affected regions.</p></div>","PeriodicalId":544,"journal":{"name":"Environmental Monitoring and Assessment","volume":"197 4","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143698620","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}

These climatic differences, along with the slope position, aspect, slope, and bedrock characteristics, have led to the development of soils with different characteristics. In this study, 32 sites were sampled from pure oriental beech forests on andesite bedrock material in the Borçka and Akkuş regions to prove the effect of environmental factors on soil properties. Soil profiles were excavated in the sample plots and soil sampling was carried out according to genetic soil horizons. Two hundred seventy-five soil samples (128 undisturbed) were taken from the excavated soil profiles, and physiological soil depth (PSD), absolute soil depth (ASD), and humus forms were determined. In soil samples, soil pH (H₂O and KCl), soil organic matter (SOM), total exchangeable bases (TEB), field capacity (FC), wilting point (WP), sand, silt, and clay were analyzed. Bulk density (BD), available water capacity (AWC), and soil organic carbon (SOC) were calculated. Independent <i>t</i>-test results showed that the average values of selected soil properties differed by region. Significant correlations between soil properties were determined. Soil pH, SOM, SOC, TEB, BD values, and sand contents of very-humid and sunny Borçka region soils are lower than those of moist and shady Akkuş region soils. Especially, low soil pH and TEB values are most likely the results of leaching. The high amount of clay and AWC, excess of PSD and ASD, and low amount of SOC suggest that weathering conditions are more suitable in this region. Podsolized gray brown forest soils are dominant in the Borçka region, while gray brown forest soils are dominant in the Akkuş region. It should not be overlooked that due to the acidification of the soils of the research area, the nutrition-growth relations in forest ecosystems will deteriorate.
