Abstract:: ... Air pollution is a major health issue, notably due to the presence of potentially toxic particulate matter with a diameter of lower than or equal to 2.5 µm, named ‘PM2.5.’ There is, however, few precise knowledge on the sources, fate and toxicity of particulate matter, notably because there is a lack of method to trace particulate matter in the long term and over large distances. Therefore, we pre ...

Abstract:: ... The presence of contaminants in potable water is a cause of worldwide concern. In particular, the presence of metals such as arsenic, lead, cadmium, mercury, chromium can affect human health. There is thus a need for advanced techniques of water decontamination. Adsorbents based on cerium dioxide (CeO₂), also named ‘ceria,’ have been used to remove contaminants such as arsenic, fluoride, lead and ...

Abstract:: ... Gene delivery is the process of introducing foreign genetic material, such as DNA or RNA, into host cells. Gene therapy utilizes gene delivery to deliver genetic material with the goal of treating a disease or condition in the cell. Actual viral vectors may have side effects, while actual systems using metal nanoparticles for gene delivery are toxic. Therefore, we designed here a biocompatible tri ...

Subject:: aldehydes; byproducts; ethanol; microwave treatment; potassium carbonate; pyridones; solar thermal energy; toxicity
Abstract:: ... Pyranopyridine derivatives are an important class of heterocyclic compounds due to their biological activities such as antitumor and antibacterial. However, conventional procedures for their synthesis produce large amounts of toxic by-products. Therefore, there is a need to develop simple, efficient and environmentally benign procedures. Here, a one-pot multicomponent protocol is designed for the ...

Abstract:: ... Glyphosate is a broad-spectrum toxic herbicide that has entered the environment. Advanced oxidation processes efficiently remove various persistent organic contaminants. In particular, generation of sulfate radicals based on catalytic sulfite oxidation is promising, but previously used Fe(II/III) catalysts have reduced activity at pH above 4 due to precipitative deactivation. Therefore, here we te ...

Subject:: heavy metals; homeostasis; humans; metabolism; metabolomics; metalloids; microRNA; oxidative stress; phytoremediation; plant growth; pollution; proteomics; toxicity; transcriptomics
Abstract:: ... Pollution of plants by heavy metals is a critical health issue because metals can be transmitted to animals and humans. Heavy metal exposure induces an oxidative stress in plant, resulting in cellular damage and altered cellular ionic homeostasis. As a consequence, plants start detoxification mechanisms. Here, we review heavy metal toxicity and impact. We discuss metabolism and detoxification stra ...
