TL;DR: The findings suggest that mining operations play an important but underappreciated role in the generation of contaminated atmospheric dust and aerosol and the transport of metal and metalloid contaminants, and highlight the need for further research in this area.

TL;DR: The size-fractionated chemical characterization of atmospheric aerosols sampled over a period of a year near an active mining and smelting site in Arizona show that arsenic and lead concentrations follow a bimodal distribution, with maxima centered at approximately 0.3 and 7.0 μm diameter, and it is hypothesize that the sub-micron arsenic andLead are the product of condensation and coagulation of Smelting vapors.

TL;DR: In this paper, a review article describes the nexus between concepts of Circular Bioeconomy, Zero Waste Technology, Sustainable Development, Biorefineries, and alternatives and research efforts to generate less environmental impact.

TL;DR: In this article, the optimum particle size range of crushed moringa seeds without husk at a fixed dosage of 50 mg/L was evaluated during jar tests, and the statistical results from a Randomized Complete Block Design (RCBD) over the sources concluded that water quality was improved by 41.90-51.94%, 55.32-71.10%, and 74.42-87.73%, for chemical oxygen demand (COD), turbidity and E.coli, respectively.

TL;DR: In this paper, the adsorption/degradation of caffeine and irgasan from aqueous artificial solutions by using lignocellulosic residues (LR) impregnated with TiO2 nanoparticles was studied.
