“…The concept of "carrying capacity" is complex and disputed in the course of development (Zhou et al, 2019). Several concepts and tools have been proposed for modelling the impacts of environmental pollution on natural systems (Liao et al, 2013;Bui and Tran, 2022;Yang et al, 2022). One approach is proposed based on the data of pollutants in water bodies, the water quality standards, combined the volume of water bodies, and the retention time of water (Bui and Tran, 2022).…”

“…The assessment of MECC has been applied in marine environmental protection and contamination control, and is useful for maintaining the sustainable development of the economy-marine environment (Wang et al, 2018). There has been intensive research on MECC, which mainly focused on conventional pollutants such as ammonium, phosphate, total suspended solids, and biological oxygen (Liao et al, 2013;Bui and Tran, 2022). Nonetheless, it still requires the development of evaluation methods on emerging contaminants such as NPs.…”

Metallic nanoparticles (NPs) are increasingly being used and inevitably entering the marine environment. Therefore, the adverse effects of NPs on individual marine species have attracted increasing attentions. However, to date, the ecological risks of NPs on the marine ecosystem remain poorly understood. In this study, species sensitivity distributions (SSDs) were constructed for Ag, ZnO, CuO, and TiO2 NPs to understand their ecotoxicity to the marine ecosystem and the contribution of size effect and ion effect to the nanotoxicity. Furthermore, a case study on the assessment of marine ecological risk and marine environment carrying capacity of metallic NPs was performed in Jiaozhou Bay, China. The results showed the toxicity of metallic NPs to marine species following the order of Ag > ZnO > CuO > TiO2. Both size effect and ion effect contributed to the toxicity of NPs. Environmental concentrations of Ag, ZnO, CuO, and TiO2 NPs are much lower than the predicted no-effect concentrations, indicating that these metallic NPs have not yet posed risks to the marine ecosystem based on currently limited measured environmental concentrations of metallic NPs in seawater. And the marine environment carrying capacity of Ag, ZnO, CuO, and TiO2 NPs in Jiaozhou Bay seawater were determined to be 5.03, 8.72, 93.06, and 629.79 t, respectively. The results help us understand the ecological risk of NPs in marine environments and provide a scientific basis for the sustainable development of nanotechnology.

The Province of the Bangka Belitung Islands as one of the provinces in the form of an archipelago has a number of islands that have the potential to be developed, including Bangka Island. The coastal areas on Bangka Island have similar environmental conditions, namely environmental problems due to illegal tin mining. However, the environmental conditions in each of these coastal areas have not been well mapped. Therefore, this study aims to map the environmental conditions in the coastal area of Bangka Island. This study uses a qualitative approach by describing the environmental conditions of the coastal area on the island of Bangka in-detail and in-depth. In addition, this research also communicates directly with informants or officers at the Marine and Fisheries Service and village government officials in the coastal area in question to explore in-depth information. Furthermore, this research data was also obtained from direct observation at the location of the coastal area on the island of Bangka. Through this approach, it is hoped that an overview and understanding of the environmental conditions in coastal areas on Bangka Island can be obtained and how to manage and utilize the potential that has been carried out to improve environmental quality.

“…Therefore, the MRECC began to turn to the concept of comprehensive carrying capacity including resources, environment, and social economy, that is, in a certain period and regional scope, under the condition that maintaining the structure of marine resources meets the needs of sustainable development, and the marine ecological environment function still has the ability to maintain its steady effect, the regional marine resources and environment system can carry all kinds of human social and economic activities. Most of the existing studies mainly focus on the introduction to the concept of the MRECC, operation mechanism, and single-element carrying capacity evaluation (Ariani et al, 2020;Bui and Tran, 2022;Wu et al, 2022). However, single-element carrying capacity often cannot reflect the marine resource environmental conditions accurately, and it cannot meet requirements on scientific protection and marine management.…”

IntroductionLarge-scale and high-intensity marine resource exploitation activities have brought irreversible influences on the marine resource environment and ecosystem. As an important index to evaluate the state of marine development, the marine resource environmental carrying capacity (MRECC) is vital to the sustainable development of the sea areas.MethodsIn this study, an evaluation index system was established based on the PS-DR-DP (Pressure and Support-Destructiveness and Resilience- Degradation and Promotion) theoretical model. The MRECC in Zhejiang Province from 2004 to 2018 was evaluated through the categorical arrangement polygon representation. Moreover, the coordination degree of the MRECC system was analyzed by using the coupling harmonious degree model.Results and DiscussionResults demonstrated the following from 2004 to 2018: 1) The MRECC level in Zhejiang Province increased firstly, then decreased slightly, and finally presented a slow increasing trend. 2) The mean contributions of the acting forces in the MRECC system in Zhejiang Province fluctuate between 0.64 and 0.68. It was in the high-speed unsteady growth and tended to be the ideal carrying state. The positive force tends to increase, while the negative force is generally stable or only slightly increased except for the degradation force. 3) The coupling degree and degree of coupling coordination of the acting force subsystems in the marine resource environmental system in Zhejiang Province presented a rising trend. The coupling degree ranged between 0.50 and 0.80 except for those in 2004, 2006, and 2007. The acting force subsystems in the marine resource environmental system in Zhejiang Province were generally running-in during the study period. The coupling degree type changed from mild imbalance to moderate coordination.
