Given their non-degradability, bio-accumulation, bio magnification, abundance, and toxicity through successive trophic levels, effective management strategies are crucial to addressing toxic metals. Recently, mangrove forestation regions in China have faced increasing HM pollution. This meta-analysis evaluates phytoremediation strategies employed by various mangrove species against toxic metals and organic pollutants in different provinces of China. Data on the phytoremediation potential of mangroves were collected and analyzed from 220 publications within 24 years, from 2000 to 2024. Results indicate a 28 % increase in phytoremediation potential in China. Notably, significant phytoremediation was observed in <em>Bruguiera sexangula</em> (33 %) in Hainan, <em>Kandelia abovata</em> in Guangdong (27 %), Zhejiang (25 %), Liaoning (26 %), and Tianjin (6 %), <em>Avicennia marina</em> in Shandong (22 %); Sonneratia <em>apetala</em> (3 %) in Jiangsu, <em>Bruguiera gymnorhiza</em> in Fujian (9 %) and <em>Rhizophora stylosa</em> (6 %) in Guangxi province. Additionally, significant accumulation of HMs was observed in sediments (5 μg/g), plant parts (3–20 μg/g), and soil (7 μg/g).

Until now, it remains unclear as to whether or not enclosing mangrove-mud coasts using multiple concrete structures for erosion control is ecologically feasible. The authors used the Tien Giang Protected Mangrove Forest (Tien Giang PMF), Tien Giang Province, the Vietnamese Mekong Delta, as a case study to partially address this question. The authors investigated the relationship between the construction of multiple shoreline and offshore structures constructed along the Tien Giang coast (TGCPS) and the protection of Tien Giang PMF through 2024 in terms of shoreline changes, changes to mangrove vegetation cover, and strong mangrove growth in the absence of the TGCPS protection. This study involved the analysis of shoreline changes over multiple years (2000 and 2024), calculation of the enhanced vegetation index (EVI), in addition to ground truthing, and field investigations. The authors found that the shoreline of Tien Giang PMF has changed despite the construction of the TGCPS. TGCPS were constructed in areas of moderate to high erosion and had a low level of mangrove growth in the surrounding areas. Mangrove forests survived and grew strongly in areas without protection by TGCPS. The survival of the mangrove forests was threatened by multiple threats. Therefore, the combination of shoreline and offshore structures is acceptable as a short-term strategy in a specific area to control eroding muddy coast. However, it is therefore not ecologically feasible to enclose an entire coast using multiple shoreline and offshore structures without properly considering the local hydrodynamic elements. Instead, a holistic approach should be designed with rigorous hydrodynamic studies, and the placement of structures must be strategic and well-studied.</div></div>","PeriodicalId":11490,"journal":{"name":"Ecological Engineering","volume":"219 ","pages":"Article 107678"},"PeriodicalIF":3.9,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144147076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Evaluating these projects is crucial for developing more sustainable solutions. To address this issue, we develop a comprehensive evaluation framework that combines emergy analysis (donor side) and economic analysis (receiver side) to assess the value of five key ecosystem services (ESVs) using 25 soil and water conservation projects (SWCPs) as case studies. Furthermore, we apply partial least squares-structural equation modeling (PLS-SEM) to analyze the interaction mechanisms among drivers, including measures factors (<em>measures</em>), terrain factors (<em>terrain</em>), environmental factors (<em>environment</em>), and climatic factors (<em>climate</em>). The results show that after the SWCPs construction, although increase in the total ESs value (ESV_T) have been found, the decrease of water conservation is demonstrated from both emergy and economic analysis. Carbon sequestration increased in all studied SWCPs expect the Gaocang river small watershed. Inconsistent results from the two adopted methods suggest that the ecological engineering evaluation should consider from both donor side and receiver side. Tradeoffs among ESVs, most notably in soil retention and water conservation pair, suggest the SWCPs are uncoordinated with local ESs. Results derived from our proposed indicators show that the emergy sustainability index (ESI) of more than half of the studied SWCPs decreases, while the cumulative present value of 8 SWCPs also declines. Finally, we find that terrain and climate are the primary drivers of ESVs increases, whereas environment and measures have the most significant negative impacts. <em>Measures</em> weakens the positive effect of <em>terrain</em> while amplifying the negative effect of <em>environment</em>.

After seven monitoring seasons (November to April), the main results can be summarized as follows. Nitrate removal efficiency and nitrate removal rate were on average 59 % and 5.5 g N m⁻³ d⁻¹, respectively, indicating that microbial denitrification takes place in winter at water temperatures &lt;8 °C. After initial flushing, the bioreactor acted also as a sink for phosphorus (ca. 61 % TP load reduction). However, as a negative side effect, the bioreactor released organic carbon and the TOC load increased by ca. 59 % at the outlet as compared to the inflow. The results indicate further that the hydraulic retention time is crucial for an optimal management of denitrifying bioreactors. Increasing the hydraulic retention time leads to greater nitrate removal efficiencies and vice versa. In contrast, water temperature fluctuations throughout the drainage season did not influence the performance of the bioreactor.

In this study, we use historical data to evaluate how the channelization of the river and its restoration 40 years later affected the aquatic biodiversity. Generally, and as expected, we observed a significant reduction in the taxon richness of aquatic plants and EPT taxa (Ephemeroptera, Plecoptera, and Trichoptera) in response to the channelization, especially taxa associated with backwaters. As hoped, the restoration mediated an increase in taxon richness for both aquatic plants and EPT taxa. This positive response took place immediately after the restoration (1 year) and persisted throughout the study period (10 years). However, taxon richness did not reach the pre-channelization levels. Especially, we observed that the recovery of backwater-associated taxa was limited. The main reason for this is likely that only 5.8 % of the original backwater area was recreated and, additionally, that natural regeneration of these areas relies on natural hydromorphological processes that might take several decades. Furthermore, the possibility of several taxa to recolonize from other and distant areas is poor, reflecting today's rarity of backwater habitats in Danish rivers.
