Summary: A series of biochars and modified biochars were prepared using macadamia nut shell as raw material and different modifying agents. These adsorbents were found to exhibit consistent adsorption behaviors according to the pseudo second-order kinetics model and the Langmuir equation. BC-CMC showed the highest adsorption capacity for Zn2+ and also demonstrated better desorption performance and reusability. Furthermore, BC-CMC exhibited higher adsorption capacity for Cu2+ and Pb2+. The adsorption mechanism of BC-CMC for Zn2+ was proposed based on the results.

Summary: This study investigates the use of iron-modified biochar (Fe-BC) for the remediation of lead (Pb) and cadmium (Cd) contaminated agricultural soils. The results show that 2% Fe-BC treatment significantly improves the growth of wheat plants and enhances soil nutrient availability, while reducing the toxicity of Pb and Cd. Therefore, Fe-BC is a promising solution for remediating contaminated soils and improving soil fertility.

Summary: This study investigated the immobilization effect of sulfoaluminate cement modified biochar (SBC) on Pb and Cd in the soil-plant system. Results showed that SBC effectively immobilized Pb and Cd in the soil through cation exchange, complexation, and gel encapsulation. SBC also changed the soil physicochemical properties and indirectly influenced the speciation transformation of Pb and Cd, resulting in reduced uptake by romaine lettuce.

Summary: This review systematically examines the chemical and toxicological transformations of secondary organic aerosol, secondary inorganic aerosol, and metal species in PM2.5 under photochemical conditions. Major SOAs are found to be more toxic than their precursors, while major SIAs are less toxic. The toxicity changes of metal species depend on the specific metal and the photochemical reaction.

Summary: Bioremediation and phytoremediation are cost-effective and environmentally friendly techniques used for remediation of contaminated sites. 24 articles in Critical Reviews in Environmental Science and Technology (CREST) from 2018 to 2022 focus on the application of these techniques. Bioremediation employs microorganisms to degrade contaminants, while phytoremediation uses plants to remove and change contaminants. However, these techniques have limitations such as lengthy remediation periods, environmental sensitivity, and nutrient deficiency. Improvement strategies including immobilization of microorganisms, construction of microbial consortia, and use of amendments have been employed to overcome these limitations.

Summary: Agricultural films are widely used in high-intensity agriculture, but the low recovery rate leads to an accumulation of plastic mulch in agricultural soils. This study focuses on the exposure impact of BBP, a chemical introduced into soil ecosystems through the accumulation of plastic mulch, on earthworms. The study explores the effects of BBP on the digestive system, oxidative stress, and neurotoxicity in earthworms, providing insights into the molecular mechanisms underlying these effects.

Summary: Understanding the sorption behavior of ciprofloxacin (CIP) on purple soil is crucial for minimizing environmental risks. This study investigated CIP sorption onto different components of purple soil and found that organic matter (OM) was the main contributor, while dissolved organic matter (DOM) affected CIP sorption. Mechanistic insights revealed that H-bonds and 7C-7C interaction dominated the sorption onto OM, and CIP sorption was faster and easier on minerals than on OM. Overall, these findings have important implications for understanding CIP sorption in purple soil.
