Summary: This study assessed the efficacy of H2O2 oxidation on biodegradation in field-contaminated and weathered soil containing high concentrations of petroleum hydrocarbons. The results showed that the addition of oxidants removed some organic carbon but had limited effect on the degradation of petroleum hydrocarbons. Moreover, the addition of oxidants limited the viable concentration of microorganisms, altered the composition of soil microbial communities, and created inhibitory conditions in soil.

Summary: This study explores the effects of Fenton pre-oxidation under different conditions on the indigenous bacterial communities and the mechanism of soil C/H conversion and rapid degradation of long-chain alkanes. The results show that the rapid degradation group has a shorter half-life period compared to the slow degradation group. After pre-oxidation, the bacterial quantity and ammonia nitrogen consumption are higher in the rapid degradation group, leading to a higher C/H conversion rate and degradation rate of long-chain alkanes. The study also reveals changes in the bacterial community after proper pre-oxidation.

Summary: The study examined the impact of soil texture and degree of compactness on total porosity and distribution of macro-, meso- and micropores. It found that total porosity and macroporosity are dependent on compactness and silt plus clay content, while meso- and micropores are mainly affected by particle size distribution. The findings suggest that increasing compactness may reduce total porosity and macroporosity, with meso- and micropores being more sensitive to changes in particle size distribution.

Summary: This study selected 41 pedons from weathered clastic sedimentary rocks to evaluate the uniformity of parent material and soil profiles. The results can be helpful in distinguishing argillic horizons and identifying differences among different soil profiles in quantitative soil classification. Various analyses, such as Ti/Zr ratio, particle size distribution, morphological characteristics, physical and chemical properties, and geochemical element characteristics, were conducted to quantitatively assess the uniformity of parent material and soil profiles. The coefficient of variation (CV) of soil properties was used as an input variable for the random forest model to assess soil profile uniformity. The results showed that the parent materials exhibited uniformity in terms of geochemical elements, but there were discontinuities in particle size caused by different surface erosion forces. In addition, color differences and sudden changes in generalizable horizon development indices were observed in some profiles. The physical and chemical properties, as well as geochemical elements, varied greatly due to complex sedimentary rocks and different terrain conditions, resulting in inhomogeneous soil profiles. Pedogenesis, slope deposit, and soil forming processes played a role in achieving soil profile uniformity. The random forest model showed that the CV of clay-free particle size distribution was the best input variable, and the CVs of Al, Si/Al ratio, clay, total phosphorus, and Na were convenient input variables for assessing soil profile uniformity.

Summary: The effects of weathering and decompaction were studied on the Opalinus Clay in northern Switzerland using a drillcore profile. The rock below 16 m depth showed dissolution of certain minerals and organic matter and an increase in Fe reduction level. Porosity decreased with depth and pore-water composition evolved from fresh water to a Na-SO4-Cl type. The interpretation of rock properties and water analysis suggest substantial weathering occurred during Pleistocene stages with lower ground-water table.

Summary: This study assessed the migration of plasticizers from modeled and commercial polyvinyl chloride (mPVC and cPVC) to poly(dimethylsiloxane) via artificial sebum to mimic dermal migration. Various factors affecting migration of phthalic acid esters (PAEs) from PVC products were investigated. Results showed that the migrated mass and migration ratio of PAEs increased over time, but the migration rate decreased. Migration rate was influenced by sebum mass, contact time, temperature, and pressure. Low-molecular-weight PAEs migrated in higher amounts than high-molecular-weight PAEs. Diffusion of all PAEs in mPVC was temperature-dependent, with diffusion coefficients ranging from 10-13 to 10-15, 10-12 to 10-14, and 10-10 to 10-12 cm2·s-1 at 25°C, 40°C, and 60°C, respectively. The study also found that migration depended on the total PAE content of the product. The daily exposure doses of the plasticizers were estimated to aid in assessing dermal exposure risk.

Summary: Metal contamination and other geochemical alterations disrupt microbial composition and functional activities, leading to disturbances in biogeochemical cycles. This study investigated the distribution of total mercury (THg), methylmercury (MeHg), and trace metals in anthropogenically affected sediment. The microbial communities and functional gene profiles were analyzed to explore their relationship with Hg-methylation and geochemical features. Results showed that THg and MeHg levels increased towards the lower horizons of the sediment cores, while Al, Fe, Mn, and Zn were the major metals present at all depths. The enrichment and contamination indices indicated high concentrations of trace metals in the anthropogenically affected sediment. Various functional genes and dominant microbial taxa were detected, with correlations between major taxa and geochemical variables suggesting the significant impact of sediment geochemistry on microbial communities and biogeochemical cycles. Archaeal methanogens and bacterial phyla Chloroflexi and Firmicutes were also implicated in the enhancement of MeHg levels. Overall, these findings provide insights into the microbial communities involved in Hg-methylation process and other biogeochemical cycles.
