“…For example, studies of ice/snow core records from the Swiss Alps from the 1650s to 2000 revealed that atmospheric Cu concentrations increased significantly to peak values towards the end of the 20th century (Barbante et al, 2004). Similar trends were also reported from the Baltic Sea (Shahabi-Ghahfarokhi et al, 2021). In addition, local long-term monitoring revealed that aquatic Cu concentrations decreased by 47 % between 1985 and 2000 in the Scheldt Estuary and Belgian coastal zone (Gao et al, 2013).…”

“…However, the background threshold obtained by 2δ Iterative analysis is slightly lower than the other three methods. On the one hand, the purpose of iterative analysis is to construct data into a normal distribution and eliminate more outliers in the process of iteration [59]. On the other hand, the average value is used as the final result of this method.…”

Variability in the distribution of natural total Sb and Cd in freshwater sediments leads to difficulties in background value (BV) determination. This study aimed to establish a method to determine BV more accurately by investigating the vertical distribution of Sb and Cd in sediment cores collected from a typical river in alluvial plain in China and revealed the factors that control the variation of Sb and Cd BV, which has not been studied in alluvial freshwater sediment. The results suggested that uncontaminated samples for BV calculation should be determined by statistical analysis as human and natural disturbance led to high variation in contamination depth, from <5 cm to >55 cm. The sequential chemical extraction method showed a considerable amount of non-residual fractions of Sb and Cd, which accounted for 48% and 43% of the total, respectively. Acid extractable Cd (16%) was associated to the limestone geology in the area. Fine particles which governed by sedimentary environment contained more natural Sb and Cd, as strong positive correlation was found between clay content and Sb concentration (r = 0.89, p < 0.01), as well as Cd concentration (r = 0.54, p < 0.01). Based on these findings, a method combined with standard deviation and geochemical method was established to calculate the BV of Sb and Cd, and counter maps were made to cover the variation of BV in the Taipu river sediment. The pollution level has been evaluated by the geoaccumulation index more accurately.

“…In the above-mentioned cores, the deepest sediment layer corresponds to 1910 or earlier, depending on the length of the core and the sedimentation rate. The direct methods (Gałuszka and Migaszewski, 2011;Shahabi-Ghahfarokhi et al, 2021a were used to estimate the BC if not reported in the selected works.…”
