Contamination Levels

<p>Researchers have measured aerial gamma-rays using remote measurement devices to estimate the radionuclide concentrations in soils. However, an issue arises when measuring air dose rates in forested areas, where canopies exist between the remote sensing device and the ground. When researchers do the reverse conversion from soil contamination levels to the air dose rates, the conversion formula is derived by assuming a flat ground surface (Jacob et al., 1994; Saito and Jacob, 1998); however, topography in forested areas is often not flat. This study examines the relationships among the air dose rates under the canopies, topography, and the soil contamination levels on forested hillslopes in Fukushima, Japan. Gamma-ray air dose rates were measured using a hand-held scintillator during the summer of 2018 (two days), and in the winter of 2019 using KURAMA, a portable scintillator carried in a backpack (one day). This study employed numerical methods, including semivariogram and R's CAR (Companion to Applied Regression) package, to find aerial gamma-ray activities' spatial structure and the optimal combinations of topographic predictors. The survey routes and soil sampling points did not coincide completely. Thus, spatial and temporal reorganizations and re-definitions of the spatial boundary to incorporate the air (boundaryless mass), topography (three-dimensional structure), and soil samples (point measurements) were needed to overcome data analysis challenges. Some preliminary results show that the median air dose rate on a summer day with stronger winds (wind speed 7.1 m/s) was closer to the one on a winter day than to the median on the other summer day with calm air. Distance dependency (semivariogram range) on the windy summer day and the winter day was 30 to 60 m. Distance dependency on a summer day with calm air was much longer, > 500 m. The aerial gamma-ray levels were not in a linear relationship with the elevation. Meanwhile, the areas under evergreen trees showed higher air dose rates (3-8 %) than the areas under deciduous trees in absolute measurements. However, the differences were not statistically significant. The combination of slope degrees, hillslope aspects, and curvature or upslope distance best described the air dose rates, depending on the survey routes, although their predictabilities (R<sup>2</sup>) were low, 0.35 at the most. The air dose rates, which were estimated from soil samples' effective relaxation mass depths, did not correlate with the actual air dose measurements, but this result is under further investigation. This study's complete results will provide additional consideration points to the gamma-ray air dose vs. soil contamination assessment in the forested areas.</p>

Effective Inclusion

The forest litter and underlying mineral topsoil are typically sampled and analyzed separately although they are in a dynamic balance, which ensures macro- and microelement cycling in the forest ecosystem, including the flux and accumulation of xenobiotics in the contaminated sites. Although the national legal regulations specify single limits of element concentration for the entire “topsoil” layer, irrespectively of the kind of materials resting at the earth surface down to the specified depth, the direct analysis of bicomponent forest topsoil (litter + mineral topsoil) was problematic because of the lack of a suitable sampler. The paper presents a comparative analysis of Cu, Pb, and Zn concentrations in the forest topsoil layers (0–25 cm), sampled using a new construction sampler invented for a joint collection of the litter layer and underlying mineral layer (to the specified depth). Litter samples (using a steel frame), mineral topsoil samples (0–25 cm, using gouge auger after litter removal), and mixed topsoil samples (0–25 cm, including litter) were collected in 16 replicates from four variably contaminated plots (copper mining and smelting area) afforested with poplar or pine. Pseudo-total concentration of Cu, Pb, and Zn was analyzed after sample digestion in aqua regia. The concentration of elements in the samples consisting of jointly collected litter and mineral layer was noticeably higher than in the samples consisting of the mineral topsoil only, which confirmed the effective inclusion of the litter. The concentrations of trace elements measured in the samples of jointly collected litter and mineral topsoil did not differ (NIR Fisher test at p < 0.05) from the concentrations calculated using the data for litter and mineral soil separately collected and analyzed, which confirmed the usefulness of the new sampler for reliable collection of the forest topsoil samples without skipping any material which may influence the results of soil contamination assessment and risk assessment.

Barapukuria Coal Mine

Coal mining areas in Bangladesh are exposing to extreme environmental problems due to the mobilization of heavy metals in the surrounding region. To assess the persisting risk, several soil samples were collected from the nearby coal mine areas. The amount of pollution of heavy metal has been calculated to determine the extent of the contamination. Soil contamination assessment was carried out using pollution evaluation indices such as heavy metal pollution index (HPI), the degree of contamination (Cd), and the contamination factor (CF). The concentration of S, As, Ba and, F exceeded the maximum concentration level in some soil samples. The HPI and the Cd yield similar results. The CF shows strong similarities with the Cd and gives a better evaluation of pollution levels. HPI indicates that about 71.42% of samples exceed the high level. Cd and CF show that about 71.42% sample is highly contaminated by trace element and 14.28% sample is highly contaminated by S, Cl, and F. Based on radioactive element analysis about 14.28% samples show medium contamination level. The findings of this research help us to assess the level of soil contamination and the extent of environmental and health concerns in the region of the Barapukuria coal mine.

Abstract This paper discusses new regulations on the assessment of soil contamination and the principle rules for remediation of contaminated sites included in the Environmental Protection Act, amended in 2014., as well as in related implementing legislation of 2016. In place of soil quality standards and the requirement to bring soil to the state that meets the standards, the new rules of contamination assessment and new remediation criteria have been introduced, based on environmental risk assessment. Similar rules are becoming increasingly common in many countries. This article provides general knowledge on the principles for the assessment of environmental risks associated with soil contamination, taking into account its two fundamental aspects: human health risk and environmental risk. On this background, the paper presents the principles of the assessment on soil contamination contained in the Regulation 1395 (2016) of the Minister of the Environment, as well as the rules for the choice of remediation method and design of remedial actions that should be basically aimed to eliminate the risk to human health and the environment.
