Summary: This study aimed to investigate the possibility of reducing heavy metal pollution in the soil of the Reghaia wastewater treatment plant (WWTP) site in Algeria through phytoremediation. The results showed that plant growth parameters were decreased on the polluted soil, but improved growth was noted when the polluted soil was amended with fertilizer. Cultivating plants in polluted soils attenuated heavy metal pollution rates, although these rates were not very high and the addition of fertilizer did not increase them. The tested plants were found to be more suitable for phytostabilization rather than phytoextraction.

Summary: In recent decades, minimizing waste generation and implementing recycling/reuse policies have become important strategies to reduce waste quantities and promote alternative waste recovery. Organic waste accounts for 46% of the total global solid waste. Organic waste can be utilized in various ways, including serving as fertilizer and soil amendment, for energy recovery, and for the production of chemicals. The disposal and reuse of sewage sludge is identified as a future waste problem. The amount of sludge generated worldwide has increased dramatically and is expected to further increase in the coming years. Many developed countries are focusing on sewage sludge treatment to improve its quality and safety for surface application. Sewage sludge pyrolysis is considered to be an economically and ecologically acceptable method for the beneficial reuse of sewage sludge. This method offers several advantages, such as significant volume reduction, elimination of pathogens and hazardous compounds, immobilization of metals in solid residue, and stabilization of organic and inorganic fractions in the form of pyrolytic residues (biochar). The biochar produced from sewage sludge pyrolysis is pathogen-free and rich in carbon and nutrients.

Summary: Sewage sludge (SS) is widely used as a soil conditioner due to its high content of organic matter and nutrients. This study found that cyanobacteria growth increased in soil amended with low concentrations of composted SS, while higher SS concentrations decreased cyanobacteria growth. However, SS significantly enhanced soil organic carbon gain and tightly-bound exopolysaccharide content. Cyanobacteria inoculation improved soil stability and had the potential for salt immobilization and soil bioremediation.

Summary: Global climate change requires the rational allocation of resources and careful waste management policy. Pyrolytic processing of agricultural, forestry, and land use waste can produce biochar ameliorants with high inorganic component content, which can enhance soil fertility. However, there is a lack of consensus on the choice of feedstock and thermal processing parameters to obtain carbon-based ameliorants. This study assessed the effectiveness of biochars produced from wheat straw and cow manure as soil amendments in terms of plant morphometric characteristics and soil properties. The results showed that these biochar amendments improved plant growth parameters and reduced soil acidity. Therefore, the thermochemical conversion of organic waste to produce biochar ameliorants can be considered an effective solution for reducing environmental impacts and enhancing soil quality to increase agricultural productivity.

Summary: Hydroxyapatite-based adsorbent (HAP(PT)) was prepared from phosphate tailings and showed efficient removal of Pb, Cd, and Zn from solution. The adsorption capacity of HAP(PT) was influenced by temperature and pH, and showed high adsorption capacity in mono-metal solutions. Selective adsorption for Pb was observed in the presence of Cd and Zn, while competitive adsorption reduced the adsorption quantity for all metals. The results provided insights into the immobilization mechanisms and potential applications of HAP(PT) in heavy metal removal and phosphate tailings recycling.

Summary: The influence of environmentally widespread soil bacteria on the biotransformation of ceria nanomaterials (NMs) has been poorly understood. This study used high-energy resolution fluorescence detected X-ray absorption spectroscopy to investigate the speciation of Ce in a model soil bacterium exposed to different sizes and shapes of CeO2 NMs. The findings revealed that the size of the CeO2 NMs drives the biotransformation process, with smaller particles exhibiting higher rates of reduction. The study also identified specific organic acid metabolites secreted by the bacterium that can induce significant reduction in CeO2 NMs.

Summary: The LUPC model presented in this paper utilizes satellite image classification (Sentinel-2) of watershed land use to estimate water pollution. It defines specific pollutant loads per unit area for each land use, called Pollutant Standard Index (PSI), and estimates the degradation and retention of pollutants until they reach the river. The model was applied to the Barigui River basin and the results indicate that organic loads can be estimated based on watershed characteristics, considering seasonal influences.

Summary: The terms "base saturation", "exchangeable bases", and "basic cations" used in Soil Science are not accurate in distinguishing different cations and can lead to confusion and misinterpretation. The most appropriate term should be Ca-Mg-K-Na saturation, rather than the current terminology. When calculating base saturation, it is sufficient to consider the sum of Ca, Mg, and K, as the Na content is usually negligible in tropical and subtropical soils. It is also suggested to abolish the use of the term "sum of bases" and instead use "sum of Ca-Mg-K" or "sum of Ca-Mg-K-Na" when necessary.
