Summary: Metal bioavailability, especially in the context of biochar amendment, influences its behavior in the soil-plant system. This study compared two methods for analyzing cadmium (Cd) bioavailability in Chinese soils, finding that biochar reduced bioavailable Cd levels in soil and decreased Cd accumulation in lettuce roots and leaves. Soil pore-water Cd was identified as the best predictor for Cd accumulation in lettuce, with transfer factor values indicating lower Cd movement from roots to leaves. Soil properties and pore-water Cd together were found to contribute significantly to root enzyme activities.

Summary: The net GHG emissions for two systems with and without dryer are 5.43 and 7.94 ton CO2 eq/ton biochar-C, but when accounting for avoided emissions from natural decay or burning of slash, the systems result in emission benefits of 2.94 and 1.18 ton CO2 eq/ton biochar-C respectively. The proposed systems break even between 567 and 573 USD/ton biochar-C without CO2 benefits, and oxidative torrefaction makes the reactor auto-thermal while avoiding the need for a separate dryer.

Summary: Agricultural soils are a major contributor to greenhouse gas emissions. Biochar, used as a soil amendment, can help mitigate climate change by reducing GHG production, increasing carbon storage, improving moisture retention, and enhancing crop productivity. However, the impact of biochar's carbon content under subsurface drip irrigation (SDI) has not been well studied.

Summary: The effect of biochar application rate on the mechanism of organic N transformation and enzyme mineralization contribution is unclear. Two 5-year field experiments were conducted in contrasting soils, revealing that biochar application rate significantly influenced soil organic carbon content, microbial biomass nitrogen content, and protease activity, while soil type significantly affected ammonium nitrogen and nitrate nitrogen content, and dehydrogenase activity. These findings provide insights into the regulation of soil nitrogen turnover by biochar application.

Summary: The urban on-road CO2 emissions are increasing, so it is crucial to manage urban on-road CO2 concentrations for effective urban CO2 mitigation. However, limited observations of on-road CO2 concentrations hinder a full understanding of its variation. Therefore, a machine learning-based model was developed to predict on-road CO2 concentration in Seoul, South Korea. The model demonstrated high precision in predicting hourly CO2 concentrations by utilizing CO2 observations, traffic volume, traffic speed, and wind speed. It also highlighted the spatiotemporal inhomogeneity of CO2 concentrations in Seoul due to different road and land-use types. The study emphasized the importance of high spatiotemporal on-road CO2 monitoring and suggested that the developed machine learning techniques can aid in managing CO2 emissions in cities with limited observation infrastructure.

Summary: This study investigates the effects of biochar addition on CO2 emissions and highlights the importance of different particle sizes of biochar in adjusting CO2 emissions from forest soil. The results show that fine biochar addition can increase CO2 emissions by improving soil nutrient content and activity of enzymes, but it reduces the bioavailability of dissolved organic carbon.

Summary: This study investigates the use of carbon materials as catalysts in the oxidation of chalcopyrite. Experimental results show that the addition of commercial activated carbon or commercial biochar significantly improves the extraction of copper from chalcopyrite ore. Analysis reveals that activated carbon adsorbs sulfur and transforms chalcopyrite into CuS, while biochar may have catalytic properties in the leaching process.

Summary: Arsenic (As) contamination is a widespread problem, and in situ immobilization with iron oxide-encapsulated carbon materials produced from olive mill waste shows promise as a remediation strategy. A pot trial using these materials demonstrated a decrease in As mobility and bioaccessibility, with higher iron content leading to greater efficiency in immobilizing As. This study highlights the potential of hydrochar and iron oxide-encapsulated carbon materials as viable options for in situ As immobilization.
