Heavy metals can enter river systems through industrial wastewater discharge, agricultural non-point runoff, urban stormwater and sewage inputs, mining and smelting activities, and atmospheric deposition. During adsorption onto suspended particles, sedimentation, and resuspension, metals such as Cd, Pb, Cr, Cu, Zn, Ni, As, and Hg progressively accumulate in sediments. Because heavy metals are persistent, non-degradable, and bioaccumulative, contaminated sediments can record historical watershed pollution while also releasing metals back into overlying water under hydrodynamic disturbance, pH and redox fluctuations, organic matter mineralization, benthic bioturbation, and dredging activities, thereby threatening aquatic ecosystem stability and human health. Using a global methodological framework with particular emphasis on Chinese river basins, this review systematically summarizes key issues in the study of heavy metal pollution in river sediments, including spatial\u2013temporal distribution and operationally defined fractionation, pollution levels and ecological risk assessment, source apportionment, and remediation and management technologies. Current evidence indicates that heavy metal contamination in river sediments exhibits pronounced spatial heterogeneity and watershed-specific characteristics. Its distribution is jointly controlled by geological background, land use patterns, source input intensity, hydrodynamic conditions, sediment particle size composition, and organic matter content. Methodologically, the field has evolved from single total concentration monitoring and exceedance-based evaluation toward integrated assessment systems that combine total concentrations, operationally defined fractionation, bioavailability, ecological risk, health risk, and source contribution. The joint use of BCR sequential extraction, the geoaccumulation index (Igeo), the pollution load index (PLI), the potential ecological risk index (RI), the risk assessment code (RAC), sediment quality guidelines (SQGs), receptor models, isotope tracing, and machine learning has substantially improved pollution identification, risk zoning, and source apportionment. Overall, research on heavy metal pollution in river sediments has shifted from descriptive judgments of whether contamination exists toward mechanistic and management-oriented questions concerning pollution sources, risk evolution, and remediation strategies. However, important gaps remain in compound pollution transformation mechanisms, regional background values and evaluation benchmarks, uncertainty in model parameters, long-term dynamic monitoring, and engineering-scale verification of remediation technologies. Future studies should strengthen multi-media, multi-scale, and long-term monitoring and further integrate fractionation analysis, toxicological effects, source apportionment models, and remediation technologies to provide a scientific basis for watershed ecological security and precision management of contaminated sediments.<\/jats:p>","DOI":"10.3390\/toxics14090765","type":"journal-article","created":{"date-parts":[[2026,8,27]],"date-time":"2026-08-27T09:00:35Z","timestamp":1787821235000},"page":"765","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Heavy Metal Pollution in River Sediments: Risk Assessment, Source Apportionment, and Remediation\u2014A Review Focusing on Chinese River Basins"],"prefix":"10.3390","volume":"14","author":[{"given":"Yuheng","family":"Tan","sequence":"first","affiliation":[{"name":"Guangdong Technology and Equipment Research Center for Soil and Water Pollution Control, School of Environmental and Chemical Engineering, Zhaoqing University, Zhaoqing 526061, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianqiao","family":"Qin","sequence":"additional","affiliation":[{"name":"Guangdong Technology and Equipment Research Center for Soil and Water Pollution Control, School of Environmental and Chemical Engineering, Zhaoqing University, Zhaoqing 526061, China"},{"name":"New Energy and New Materials Research Center, Zhaoqing University, Zhaoqing 526061, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Binyi","family":"Tao","sequence":"additional","affiliation":[{"name":"Beijing Zhongzi Huayu Environmental Protection Technology Co., Ltd., Beijing 100071, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6123-7990","authenticated-orcid":false,"given":"Huarong","family":"Zhao","sequence":"additional","affiliation":[{"name":"College of Environmental Science and Engineering, Guilin University of Technology, Guilin 541004, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinhuan","family":"Deng","sequence":"additional","affiliation":[{"name":"Guangdong Technology and Equipment Research Center for Soil and Water Pollution Control, School of Environmental and Chemical Engineering, Zhaoqing University, Zhaoqing 526061, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiayin","family":"Ling","sequence":"additional","affiliation":[{"name":"Guangdong Technology and Equipment Research Center for Soil and Water Pollution Control, School of Environmental and Chemical Engineering, Zhaoqing University, Zhaoqing 526061, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Min","family":"Dai","sequence":"additional","affiliation":[{"name":"Guangdong Technology and Equipment Research Center for Soil and Water Pollution Control, School of Environmental and Chemical Engineering, Zhaoqing University, Zhaoqing 526061, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xi","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Environmental Science and Engineering, Sun Yat-Sen University, Guangzhou 510275, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1269","DOI":"10.1080\/15320383.2023.2301499","article-title":"Concentration and ecological risk of heavy metals in river sediments of a developing country: A meta-analysis","volume":"33","author":"Shammi","year":"2024","journal-title":"Soil Sediment Contam."},{"key":"ref_2","first-page":"116","article-title":"Application of multiple indices in ecological risk assessment of potentially hazardous elements in sediments","volume":"33","author":"Liu","year":"2025","journal-title":"Environ.
