RESUMO

Waste activated sludge and food waste are two typical important domestic low-value organic solid wastes (LOSW). LOSW contains significant organic matter and water content resulting in the transboundary transfer of liquid-solid-gas and other multi-mediums, such that the complexity of microplastics (MPs) migration should be of greater concern. This article provides a review of the literature focusing on the separation and extraction methods of MPs from LOSW. The occurrence and source of MPs are discussed, and the output and impact of MPs on LOSW heat and biological treatments are summarized. The fate and co-effects of MPs and other pollutants in landfills and soils are reviewed. This review highlights the migration and transformation of MPs in domestic source LOSW, and future perspectives focused on the development of a unified extraction and analysis protocol. The objective of this review is to promote the technological development of decontamination of MPs in LOSW by sufficient understanding of the fate of MPs, their interaction with coexisting pollutants and the development of targeted preventive research strategies.

RESUMO

The uncontrolled redox activity of metal ions, especially copper, in the brains of patients with Alzheimer's disease (AD) should be considered the origin of intense oxidative damage to neurons in the AD brain. To obtain low-molecular-weight copper chelators that act as tetradentate ligands, we designed new compounds based on an 8-aminoquinoline motif with a lateral chain attached at the 2-position of the aromatic ring. Some of these new ligands, termed TDMQ for TetraDentate MonoQuinolines, are specific for copper chelation. Full characterization of these ligands is reported, as well as their affinities for CuII , and their capacities to inhibit oxidative stress induced by copper-amyloids activated by a reductant. Such metal ligands can be considered as potential anti-AD agents, as they should be able to regulate the homeostasis of copper in brain tissue.
