“…Also, the values recorded in the present work are 5-30 times lower compared to other beaches already assessed (Vidinha et al, 2006;Vetrimurugan et al, 2016). Cobalt has an affinity with Fe (Ekoa Bessa et al, 2020), however, no correlation between these elements was observed in our study, which together with high relative levels of Co, could configure anthropogenic input of this element into the environment.…”

Analyzing the presence and quantifying trace elements is of paramount importance to understand natural environmental processes and monitor the degree of anthropogenic disturbance to mitigate impacts already caused. Here, we aimed to establish a baseline of the trace elements profile and concentrations in sandy sediments of intertidal areas of three Amazonian beaches (Brazil). For each beach, sediments were collected from three different sectors (south, center, and north) and five shoreline distance levels (from the high- to the low-water mark), totalizing 15 samples per beach. The concentration of the different trace elements (Mg, Al, P, S, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Br, Rb, Sr, Y, Zr, Cd, Sn, I, Hg, and Pb) was determined by Total reflection X-ray Fluorescence spectrometry. Sediment was also characterized for its grain size, organic matter, and pH. To assess possible enrichment due to anthropogenic activities we compared trace element levels with the values for the Earth’s crust and calculated pollution indexes: geoaccumulation index (Igeo), ecological risk index (RI), contamination factor (CF), pollution load index (PLI), and sediment quality guideline (SQG), threshold effects level (TEL) and probable effects level (PEL). Individual trace metal concentrations did not vary significantly between beaches, sectors, or sample levels, evidencing a homogeneity of trace elements composition and concentrations across this environment. Igeo indicated 62.2% of the sampling stations uncontaminated, 20.0% from uncontaminated to moderately contaminated, and 4.44% (two sampling stations) strongly contaminated, the same two areas classified as high ecological risk by RI. Most of the sampling points presented low CF. Cadmium and Hg were the only elements that showed moderate to very high values of CF. According to the SQGs, 77.7 and 8.8% of the sampling points presented values above the moderate threshold effect level (SQG-TEL) and probable effect level (SQG-PEL), respectively. All points were classified as non-polluted according to the PLI. Our results show that the three beaches present safe levels of almost of the elements demonstrating the good state of preservation. Most of the indexes classified the sampling points as non-polluted, except for Cd and Hg in a few specific sampling points.

“…Therefore, possible sources cannot have a geogenic origin and heavy metal inputs could have an anthropogenic origin. The heavy metal concentrations of Portugal beach and dune sediments (Vidinha et al 2006) were higher than those of Kizkalesi area. However, Ni, Mg, Mn and Cr contents of Kizkalesi coast dune sediments were higher.…”

“…3). There have been several heavy metal studies conducted on beach and dune sediments in various regions (Turekian and Wedepohl 1961;Vidinha et al 2006). Comparisons of average heavy metal contents from the study area with those from Portugal dune sediments revealed some differences ( Table 3).…”

“…Therefore, it is important to determine heavy metal concentrations and to investigate their geochemical distribution. There have been several recent studies on distribution of heavy metals along coastal areas (Evans 1971;Scoullos and Dassenakis 1982;Duan 2000;Wolf et al 2001;Araujo et al 2002;Rocha et al 2005;Abrantes et al 2005;Vidinha et al 2006;Ramirez et al 2005). To explain the differences between geogenic and anthropogenic sources of heavy metals, some methods have been developed.…”

The aim of this study was to investigate variations in heavy metal concentrations and natural and artificial sources of heavy minerals in beach and dune sediments along Kizkalesi (Mersin) coast in Turkey. To this aim, sand sediment samples were collected from 20 locations throughout Kizkalesi coast and concentrations of Zn, Ni, Cu, Co, V, Mo, Ag, Sb, Sn, Cd, W, Hg, Pb, As, Si, Al, Fe, Ca, Mg, S, K, Na, Cl, Ti, Mn and Cr were determined. Simple analyses (frequency histogram), multivariate analyses (Coefficient correlation, Cluster Analysis), Principal Component Analysis, Model Summary and ANOVA were used to analyze the concentration values. Al, Fe, Mg, Cl, Ti, Mn, Cr and Ni were dominant heavy metals. Principal Component Analysis revealed six principal components. It was confirmed by Cluster Analysis. Based on the Hierarchical Cluster analyses, three different general groups were formed at a 50% arbitrary similarity of Q-type level. The frequency histogram indicated that W, Ag, Co, V, Cu, As, Sn, Ni, Zn, Pb, Cr, Cl and Mg concentrations originated from the nearby area, while Mn, Ti, Al and Fe Mg concentrations came from either the nearby area or moderately remote sources. Data from the study area showed that the Model Summary (based on R(2)=100%) was sufficient for the statistical data and that the Model ANOVA (variations of Pb) had a high explanatory power. The region lying on Miocene carbonate rocks of the Tauride belt were affected by the contaminants of anthropogenic origin that included coastal deposits, coastal erosion, the Kizkalesi settlement area, urban wastes, Mersin-Antalya road extending parallel to the shoreline and disposal sites of hotels.

The analyses were performed around the Tenerife Island at several points.…”

Metals and metalloids are usually bound in the fine-grained (<63 lm) fraction of the marine sediments, due to the high surface area and humus content. In this fraction, the metals have a greater biological availability than in the coarser fractions. In the present work, the content of total metals and metalloids, their distribution and accumulation in marine sediments collected in the Tenerife Island (Spain) was evaluated. Thirty-six samples collected near the nine points of discharge located along the entire coast were analyzed. The concentration of 47 elements was determined by microwave-assisted digestion followed by Inductively Coupled Plasma Mass Spectrometry (MAE-ICP-MS) analysis. Important levels of contamination from a high number of elements were found in samples, the concentrations of Pb was higher than the ecotoxicological assessment criteria (EAC) established by the OSPAR (5 mg kg À1 ) in some cases. Principal component and correlation analysis were developed and the results obtained indicated that there are two principal sources of anthropogenic pollution, with a large number of elements related to them. The amounts of 13 elements found in the sediments of the sampling point of Santa Cruz of Tenerife, principal city of the island, were higher than those found in the other locations. Modifications in the sea bed were also detected due to industrial wastes; concentrations of metals related to metallurgic activities have increased in the industrial area while the proportion of original igneous sediments decreased. The mobility of the pollutants, according to the sea currents, was also evaluated. For some of the analyzed metals, differences between sampling points in agreement with the direction of the marine currents in the area were obtained. The large number of elements analyzed allowed the development of a geochemical characterization of the three slopes of the island. Significant differences were observed for some elements.
