Microplastics are ubiquitous in aquatic ecosystems, but little information is currently available on the dangers and risks to living organisms. In order to assess the ecotoxicity of environmental microplastics (MPs), samples were collected from the b

International audience; The mass and volume concentration of nanoplastics is extremely low, but incredibly high in terms of surface area; this is expected to increase their toxicity through the ab/adsorption and transport of chemical co-pollutants su

Publikováno v: Soft matter. 18(37)

Since the introduction of polyethylenimine (PEI)/acrylamide-based polymer gel systems in the late 90's, the literature knowledge on the crosslinking mechanisms between the various polymers (PAM, PHPA, and PatBA) and the crosslinker (PEI) was only lim

International audience; Nanoplastics are pieces of plastic debris of mixed shape and chemical composition, which can be present in the air, soil, freshwater bodies, seas, biota, and our diet. We know little about the prevalence of nanoplastics and th
