Article Abstract

With the increased global focus on environmental protection, green ships have emerged as the cornerstone to the maritime industry's long-term development. Based on the knowledge graph method, this paper uses bibliometric analysis to examine the research progress of green ships in a multidimensional perspective. Firstly, sort out the definition and connotation of green ships, and clarify their greening requirements in the whole life cycle. Bibliometric analysis of relevant literature using the bibliometrix package; secondly, combined with the virtual analysis method-VOSviewer software, it explores the current research status of green ships from the multi-dimensional perspectives of technical, operational and policy. The results indicate that the hot spots in technical measures are "green energy", "ship optimization" and "waste heat recovery"; the hot spots in operational measures are "speed optimization" and "liner shipping"; and the hot spots in policy measures are "market mechanism" and "international regulations".

Dried blood spot (DBS) technique has gained significant attention due to the growth of decentralized diagnostics. This technique reduces the number of hospital visits for patients and the workload for personnel in specialized hospitals. This microsampling method provides an environmentally friendly (green) and patient-friendly alternative to conventional phlebotomy.

Port green spaces are essential protective barriers, enhancing safety and environmental resilience in high-activity port regions. Given the intensity of human activities in these areas, understanding the factors influencing the carbon sequestration capacity and ecological benefits of port green spaces is crucial for developing sustainable green ports. This study integrated field investigations and remote sensing data to estimate carbon density and carbon sequestration capacity in the Dongjiakou Port area, examining their relationship with port green space planning.

Environmental Risk Assessment for Contaminants of Emerging Concern in the Belgian Part of the North Sea.

Integr Environ Assess Manag

July 2025

Laboratory of Environmental Toxicology and Aquatic Ecology (GhEnToxLab), Faculty of Bioscience Engineering, Ghent University, Ghent, Belgium.

Belgian coastal waters are influenced by densely populated cities, industrial activities, and marine shipping, and they are therefore subject to chemical contamination. In the NewSTHEPS project (2012-2019), more than 150 contaminants of emerging concern (CECs) were detected in the Belgian Part of the North Sea, including hormones, personal care products (PCPs), pesticides, non-hormone pharmaceuticals, phenols, and phthalates. In this study, we developed and used an automated algorithm to calculate the marine screening level predicted no-effect concentration (PNECscreen) of substances, and to identify the organisms and organism groups most sensitive to these chemicals, based on ecotoxicological data from the ECOTOX Knowledgebase.
