Summary: This study investigated the migration and transformation of heavy metals (HMs) in paddy soils from Anhui Province, China. The results showed that the distribution of HMs in soil was influenced by the particle size, with higher concentrations found in cultivated paddy soils compared to uncultivated soils. The accumulation of HMs increased with decreasing particle size, with the smallest fractions providing the highest distribution factor. The leachability behaviors of different HMs varied in different particle size aggregates, with Cr and Pb exhibiting the highest leachability in coarse fractions, while As and Cd showed significantly higher leachability in smaller fractions.

Summary: The study showed that the addition of lime and CMP amendments effectively reduced the availability of cadmium in soil and lowered the cadmium content in rice to meet national food safety standards. Adjusting soil pH and increasing phosphorous were crucial factors in reducing available cadmium. Furthermore, the addition of the amendments increased soil microbial biodiversity.

Summary: Surface soils from the main winter jujube planting base in China were collected and analyzed for six heavy metals. The concentrations of most metals were higher than the background values, but below the risk screening values for agricultural soil in China. The soils were considered suitable for winter jujube cultivation, with no pollution observed. It was suggested to control the new inputs of heavy metals through proper utilization of pesticides and fertilizers.

Summary: This study focuses on the importance of soil quality and environmental monitoring, and investigates the absorption characteristics of heavy metals in soil spectra and their distribution in a large-scale continuous space. The heavy metal contents can be accurately estimated by using features such as absorption depth, absorption area, and spectral ratio. It is found that organic matter, clay minerals, and iron/manganese oxides play a significant role in the adsorption of heavy metals in soil. Additionally, the combination of spectral absorption characteristic parameters and highly correlated bands improves the accuracy of estimation compared to using either parameter or bands alone.

Summary: With the increasing use of plastic films, microplastic pollution in agricultural soils has become a global environmental problem. In this study, it was found that propiconazole accelerated the degradation of microplastics and the adsorption and release of heavy metals. However, these effects were absent at high concentrations. Additionally, microplastics were more prone to degradation in acidic and alkaline soils. PBAT degraded faster and adsorbed and released more heavy metals than PE. The heavy metal contents in microplastics gradually approached those in soil.

Summary: This study investigated the impact of a super typhoon on the migration of heavy metals in agricultural soils. It found that heavy metal contaminations in soil were relieved to a certain extent after the typhoon, with different metals showing varying changes in their available fractions. Additionally, lead contamination slightly increased after the typhoon, indicating a different response compared to other heavy metals.

Summary: This study investigated the distribution characteristics and hazard levels of heavy metals in karst soil in a mountainous county in China. The results showed that the levels of heavy metals in karst areas exceeded the background values, while non-karst areas did not. The presence of heavy metals in karst areas was mainly influenced by carbonate rock parent material. The potential ecological risk in karst areas, especially for Cd, was higher compared to non-karst areas.

Summary: This study reviewed the accumulation and distribution patterns of heavy metals in freshwater fish in nine basins of China from 2010 to 2020 and assessed their health risks. The results showed that the pollution level of heavy metals in Chinese freshwater fish is at an intermediate level internationally. The concentration of heavy metals in artificially farmed freshwater fish is higher than that in wild fish, and the noncarcinogenic risks are higher for children.

Summary: This study used metagenomics and genomics to analyze the abundance of genes associated with heavy metal resistance and tolerance in the rhizosphere microbiome of Avicennia germinans in a semi-arid mangrove in La Guajira, Colombia. The study identified a total of 28 genes associated with tolerance and 49 genes related to resistance to heavy metals. Genes associated with Cu tolerance, particularly cusA and copA, were the most abundant. The Vibrio fluvialis isolate showed the ability to tolerate Cu, Ni, Zn, and Cd. The study provides insights into the potential of mangrove microorganisms to tolerate and resist heavy metals and the influence of salinity on their abundance.

Summary: This study analyzes the characteristics of process parameters in three lean gas ethane recovery processes and establishes a prediction and multiobjective optimization model for ethane recovery and system energy consumption. A new method for comparing ethane recovery processes for lean gas is proposed, and the addition of extra coolers improves the ethane recovery. The support vector regression model based on grey wolf optimization demonstrates the highest prediction accuracy, and the multiobjective multiverse optimization algorithm shows the best optimization performance and diversity in the solutions.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.

Summary: This study uses survey data from the Loess Plateau in China to evaluate the impact of social interaction on the adoption of soil and water conservation (SWC) technology by farmers. The study finds that social interaction increases the likelihood of farmers adopting SWC, and internet use moderates this effect. The positive impact of social interaction on SWC adoption is more pronounced for farmers in larger villages and those who join cooperative societies.
