This study investigated the geochemical background values for seven trace elements in topsoil samples collected from highland areas within Cao Bang province, Vietnam. Total concentrations of these elements were determined, revealing the following order of mean concentration: Zn > Cr > Pb > Cu > As > Ni > Co. The background values were calculated using two different methods including iterative 2δ‐technique and 4δ‐outlier test. The 4δ‐outlier test yielded the following background concentrations (dry weight) for the seven elements: As (24.41 ± 12.42 mg kg−1), Co (15.64 ± 10.57 mg kg−1), Cr (49.31 ± 33.41 mg kg−1), Cu (29.77 ± 27.14 mg kg−1), Ni (22.52 ± 13.33 mg kg−1), Pb (38.06 ± 31.48 mg kg−1), Zn (71.79 61.09 mg kg−1). The 2δ‐technique, on the other hand, resulted in the following background concentrations (dry weight) for the same elements: As (8.41 ± 8.57 mg kg−1), Co (5.06 ± 4.31 mg kg−1), Cr (26.72 ± 26.20 mg kg−1), Cu (25.31 ± 24.81 mg kg−1), Ni (8.02 ± 7.83 mg kg−1), Pb (28.12 ± 27.58 mg kg−1), Zn (51.91 ± 49.44 mg kg−1). These results provide valuable baseline data for future environmental assessments and monitoring programs in the region. They also highlight the potential impact of human activities, such as mining, on the geochemical landscape of highland areas.

“…Various cases of different kinds of toxic elements from geogenic processes have been found in excavated materials, in many countries (Cremisini and Armiento, 2016;Li et al, 2014;Li et al, 2018). In Japan, the soils containing natural contamination are frequently found to exceed the limits of leaching values regulated by the Soil Contamination Countermeasures Law (SCCL).…”

Batch leaching tests with different liquid per solid ratios and contact times were conducted on tsunami deposit soil. The chemicals of concern are arsenic (As), boron (B), and sodium (Na). Two parameters were obtained from the tests, which are the partition coefficient (Kd) and the available mass of contaminants per unit mass of soil (MT). Here, the "available mass of contaminants" refers to the mass of contaminants that will take part in adsorption-desorption reaction, but not the total mass of contaminants which are present in the soil system. Using these two parameters, temporal concentration profiles based on the analytical solution of a one-dimensional advection-dispersion equation were plotted for different contact time, and compared with the results of column leaching tests, which were conducted separately using 10-cm long and 5-cm high columns. From the comparisons, multiple sets of two parameters at different contact times are needed to express the column test results for all three chemicals. To predict the column leaching behaviour from batch test with minimum numbers of contact times, two contact times, 6 and/or 24 hours can be selected.

Arsenic-contaminated freshwater: assessing arsenate and arsenite toxicity and low-dose genotoxicity in Gammarus elvirae (Crustacea; Amphipoda)

Arsenic (As) contamination of freshwater is largely due to geogenic processes, but As is also released into the environment because of improper anthropic activities. The European regulatory limits in drinking water are of 10 μg L As. However, knowledge of the genotoxic effects induced by low doses of As in freshwater environments is still scanty. This study was designed to investigate arsenate (As(V)) and arsenite (As(III)) toxicity and low-dose genotoxicity in Gammarus elvirae, which has proved to be a useful organism for genotoxicity assays in freshwater. As(V) and As(III) toxicity was assessed on the basis of the median lethal concentration, LC(50), while estimates of DNA damage were based on the Comet assay. The G. elvirae LC (50-240 h) value we calculated was 1.55 mg L for As(V) and 1.72 mg L for As(III). Arsenic exposure (240 h) at 5, 10, and 50 µg L of As in assays with either arsenate or arsenite-induced DNA damage in hemocytes of G. elvirae in a concentration-dependent manner. Our study provides a basis for future genotoxic research on exposure to freshwater that contains low levels of arsenic.
