“…The depositional center of the gulf and local depressions are largely filled with fine-grained sediments, but sandy deposits mostly seen in the shallow coastal regions (Su and Wang, 1994). A recent study has identified through zircon age spectrum that sand derived from the western and southern Hainan Island is characterized a strong ∼100 Ma peak (Fyhn et al, 2019). The present investigation focuses on the northwest coastal region of Hainan Island, from Chengmai Town to Changhua River (Figure 2).…”

Geochemical Appraisal of Chemical Weathering and Metal Contamination in Coastal Surface Sediments, Off Northwest Hainan Island, the Gulf of Tonkin

et al. 2019

Coastal sediments not only contain a majority of trace metals, but they also act as a source of dissolved metal ions to the overlying water column. Distinguishing the level of trace metal enrichment from the natural input in sediments is therefore important to determine the distribution and sources of land-derived detritus and pollutants in the coastal region. This study investigates fine (<63 µm) and bulk (<230 µm) fractions of surface sediments from the northwest coast of Hainan Island, South China, for sedimentological and geochemical parameters to evaluate the chemical weathering conditions of source rocks and geochemical processes controlling their distribution. Among seventeen major and trace elements investigated in this study, six elements (Al, Fe, Cr, Ni, V, and Zn) varied spatially. Among four transects investigated, bulk and fine sediments from three northern transects (A, B, and C) behave spatially almost similar, but the sediments from the southernmost transect (D) are characteristically different with higher contents of trace elements because of direct riverine influence with heavy mineral dominance. Range and mean values of weathering indexes, chemical index of alteration (CIA; 59-79 and 73) and chemical index of weathering (CIW; 78-91 and 85) as well as triangular plots of silicate weathering, revealed that sediments were derived from both granitic and basaltic rocks that have undergone moderate chemical weathering processes in the provenance. Normalization of trace elements to Al and the enrichment factor (EF) for fine and bulk sediments showed higher mean EF (>2) for As, Cd, and Pb, suggesting that the sediments were likely enriched by these elements. A comparative study of trace metals concentrations and EF with other coastal regions of China, however, revealed that the study area is in a pristine environmental condition compared to other coastal regions of eastern China. Factor analysis identified three dominant sedimentological and geochemical associations, accounting for ∼70% of total variance, recognize terrigenous input, heavy mineral role and anthropogenic input in controlling the distribution of most elements in the study area.

“…These sediments can smother crops, reduce visibility thereby impacting on traffic safety and result in long-term health problems due to a decline in air quality, especially in urban areas (Goossens 2003 ). A range of techniques has been used to investigate key dust sources for targeting remedial action including, amongst others, data mining with ensemble or individual models (Gholami et al 2020a , b ), remote sensing (Filonchyk et al 2018 ), comparison of strontium ( 87 Sr/ 86 Sr) or neodymium ( 143 Nd/ 144 Nd) ratios (Yang et al 2008 ; Saitoh et al 2011 ), rare earth elements (Dukes et al 2018 ) and detrital zircon ages or heavy mineral composition (Garzanti et al 2013 ; Fyhn et al 2019 ). Since 2016, however, there has been a growing interest in applying sediment source tracing procedures using linear mixing models (Liu et al 2016 ; Gholami et al 2017a ; Wang et al 2017 ; Zhao et al 2020 ; Niu et al 2020 ), Monte Carlo simulation (Gholami et al 2019b ), Bayesian approaches (Gholami et al 2017b , 2019a ) and generalized likelihood uncertainty estimation (GLUE) model (Behrooz et al 2019 ; Telfer et al 2020 ; Gholami et al 2020c ).…”

Purpose This review of sediment source fingerprinting assesses the current state-of-the-art, remaining challenges and emerging themes. It combines inputs from international scientists either with track records in the approach or with expertise relevant to progressing the science. Methods Web of Science and Google Scholar were used to review published papers spanning the period 2013–2019, inclusive, to confirm publication trends in quantities of papers by study area country and the types of tracers used. The most recent (2018–2019, inclusive) papers were also benchmarked using a methodological decision-tree published in 2017. Scope Areas requiring further research and international consensus on methodological detail are reviewed, and these comprise spatial variability in tracers and corresponding sampling implications for end-members, temporal variability in tracers and sampling implications for end-members and target sediment, tracer conservation and knowledge-based pre-selection, the physico-chemical basis for source discrimination and dissemination of fingerprinting results to stakeholders. Emerging themes are also discussed: novel tracers, concentration-dependence for biomarkers, combining sediment fingerprinting and age-dating, applications to sediment-bound pollutants, incorporation of supportive spatial information to augment discrimination and modelling, aeolian sediment source fingerprinting, integration with process-based models and development of open-access software tools for data processing. Conclusions The popularity of sediment source fingerprinting continues on an upward trend globally, but with this growth comes issues surrounding lack of standardisation and procedural diversity. Nonetheless, the last 2 years have also evidenced growing uptake of critical requirements for robust applications and this review is intended to signpost investigators, both old and new, towards these benchmarks and remaining research challenges for, and emerging options for different applications of, the fingerprinting approach.
