The Canadian Journal of Chemical Engineering, EarlyView.Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C

Ecography, EarlyView.Where early successional forests are more flammable than old‐growth forests, forested landscapes are vulnerable to shifting into ‘fire traps' through positive feedbacks, where fire leads to more fire. These feedbacks are amplified by increased flammability driven by climate change, the presence of non‐native flammable plant species, and slowed ...

Environmental Policy and Governance, EarlyView.ABSTRACT The role of civil society organizations (CSOs) in addressing climate change is acknowledged, but engagement with questions of voice remains limited, especially in the Global South. Addressing this, this paper zooms in on (International) nongovernmental organizations ((I)NGOs) and their collaborations with domestic CSOs in the Global South on ...

Risk assessment using IEUBK model for the Naica mine tailings
Environmental Progress &Sustainable Energy, EarlyView.Abstract Mexico has a long history of mineral extraction, during which limited environmental regulations allowed the accumulation of toxic waste near communities, primarily in rural or undeveloped areas. Some of these toxic substances, such as lead, pose significant risks to vulnerable populations, particularly children aged 0 to 7 years.
