Summary: This study investigated the adsorption of heavy metals (Cd and Cr) from industrial wastewater using a series of Ca-substituted nickel zinc nanoferrites (CaxNi0.4Zn0.6-xFe2O4 (x = 0.1, 0.2, 0.3, 0.4, 0.5 and 0.6)) (CNZNFs). The effect of calcium doping and contact time on the adsorption of cadmium and chromium ions was examined, and the prepared nanoadsorbents showed high removal efficiencies for both Cd (98.25%) and Cr (51%) ions. Structural analysis confirmed the formation of spinel structured nanoparticles with varying crystallite size and porosity depending on the calcium concentration. The adsorption data was well fitted by the pseudo second order kinetic model and Langmuir isotherm model, with high adsorption efficiencies of Cd (128.20 mg/g) and Cr (23.54 mg/g) observed. The Langmuir isotherm model showed better fitting than the Freundlich isotherm model due to higher correlation coefficients for both heavy metals.

Summary: This study investigated the adsorption process of heavy metals Pb2+ and Cd2+ on tire wear particles. The results showed that the adsorption kinetics followed a pseudo-second-order rate equation with rate-controlling boundary layer adsorption and intraparticle diffusion process. The adsorption tendencies for Pb2+ and Cd2+ on the tire wear particles were studied, and the Freundlich and Dubinin-Radushkevich isotherms were found to be feasible for describing the adsorption. It was also found that the adsorption of Pb2+ and Cd2+ was mainly physisorption and the process was dependent on ambient conditions.

Summary: Industrial and pharmaceutical activities are causing environmental contamination, with heavy metals being a major pollutant. In this study, the sorption capacity of quick clays (QCs) from Canada for copper (Cu) and cadmium (Cd) was investigated.

Summary: Bioherbicides, known as nature-based herbicides, are vital for sustainable agriculture due to their ability to effectively inhibit weed growth. They enhance crop productivity by reducing competition for resources and are environmentally friendly, promoting eco-conscious farming practices. However, many bioherbicide compounds are unstable and vulnerable to environmental factors, making weed management challenging. Encapsulation techniques, particularly using polymers, offer advantages such as improved efficacy, sustainable release, and protection against environmental degradation. This study focuses on the latest developments in encapsulating bioherbicides into micro-/nanoparticles for weed management, utilizing micro-/nanotechnology to enhance application and efficacy, thus facilitating sustainable agricultural practices.

Summary: In this study, zein nanoparticles associated with the herbicide atrazine were developed and their efficacy in weed control was evaluated. The nanoformulation showed good stability and encapsulation efficiency. It exhibited greater effectiveness against the target plant, Brassica juncea, even at low doses, without causing toxicity to the crop species. The nanoparticles were captured and accumulated in roots but had limited transportation to the shoot. The atrazine nanoencapsulation did not increase the mobility of the herbicide in the soil.

Summary: Nanoformulations are developed to provide controlled release of active ingredients for reduced environmental impact. However, the toxic effects of these formulations on non-target organisms are still poorly understood. This study used transcriptomics to investigate the mechanisms of toxicity of atrazine when delivered as a nanoformulation, a commercial formulation, and the pure active ingredient. The results revealed differentiated mechanisms of toxicity between the nanoformulation, active ingredient, and conventional pesticides, providing insights for safe and sustainable design in the agrochemical industry.
