“…It showed that the accumulation of heavy metals in the sediments of Bohai Bay is significantly affected by anthropogenic factors; however, the accumulation levels remain relatively low compared to some other substantial anthropogenic input regions. The results, in conjunction with other related studies [12][13][14][15], further substantiate the influence of human activities on heavy metal pollution in water systems. Additionally, the toxicity probability of surface sediments in the northwest of Bohai Bay was determined to be 21% using the mean effect range-median quotient.…”

“…These studies usually reveal a strong correlation between heavy metal enrichment and human activities [12]. Moreover, researchers have studied the contribution of various production activities (including industrial processes, mining, agriculture, and urbanization) to heavy metal pollution in rivers and lakes [13][14][15]. Their findings indicated that the wastewater and emissions resulting from these activities contain high levels of heavy metals and can contaminate nearby waters through direct discharge or atmospheric deposition.…”

Heavy metal pollution in rivers and lakes arising due to rapid economic development has been extensively studied by various countries due to its direct impact on ecological health and human well-being. However, there is a lack of comprehensive and systematic reviews addressing the current research status of this subject. In this study, we conducted a visual metrological analysis of the literature from 2001 to 2021 using the Web of Science (WoS) and China National Knowledge Infrastructure (CNKI) citation databases. The results show that studies conducted in other countries initially outnumbered those in China; after 2010, China emerged as the foremost contributor. Furthermore, both the WoS and CNKI databases indicate active engagement of Chinese researchers through a significant proportion of published papers on metal research, with prominent contributions coming from institutions such as the Chinese Academy of Sciences (CAS) and University CAS. Nevertheless, Chinese research institutions still have relatively low total paper citation numbers and have yet to establish themselves as key players in international scientific research efforts. Additionally, core authors from different countries share substantial similarities in their research directions and focuses. Consistent research hotspots regarding heavy metals in rivers and lakes were identified across both databases, including heavy metal pollution, adsorption, human activities, water quality, and sediment.

“…Sediment is the ultimate sink of heavy metals in lakes, and thus it is widely employed as a geo-marker for assessing heavy metal pollution and environmental risks and for identifying potential pollution sources [ 8 , 9 , 10 , 11 , 12 ]. In recent years, numerous studies have been conducted to investigate heavy metals in lake sediments, aiming to determine their pollution status, ecological and health risks, as well as potential sources [ 1 , 4 , 5 , 7 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ]. These studies have furnished valuable data for comprehending heavy metal pollution in Chinese lakes.…”

Background soils are frequently utilized as a surrogate to assess pollution levels and environmental risks of heavy metals in Chinese lakes. However, there remains a lack of understanding regarding the reliability and uncertainty of such assessments. Here, we determined heavy metals (As, Cd, Co, Cr, Cu, Hg, Ni, Pb, and Zn) in sediment cores from five rural lakes in North China to evaluate the reliability and uncertainty of the assessments using background soils by comparing them with assessments based on background sediments. Comparative studies reveal large uncertainties in the assessments using background soils. Among these metals, uncertainties for Hg and Cd are relatively large, whereas those for the other metals are minor. This discrepancy is due to the considerably higher natural variability of Hg and Cd in soils and sediments in comparison to the other metals. Generally, assessments utilizing background soils underestimate pollution levels and risks of Hg but overestimate those of Cd in these lakes. Despite limited human activities around the lakes, they still received a considerable influx of heavy metals via regional atmospheric transport. Assessments of the nine metals indicate moderate to considerable ecological risks in these lakes. The risks are contributed primarily (78–89%) by Hg and Cd. This study underscores the substantial uncertainties in assessing heavy metal pollution and risks using regional background soils and emphasizes the importance of controlling atmospheric emissions of Hg and Cd to mitigate pollution in rural and remote water bodies in China.
