- Abstract:
- ... High amounts of macro and microplastic have been reported in rivers, lakes and seas. However, links between the observed pollution and their sources remain unclear. This study aims to clarify these links in the Lake Geneva basin by analysing each step of the local plastic life cycle.Two distinct approaches have been compared: (i) a top-down approach based on modelling socio-economic activities, pl ...

- Abstract:
- ... Organic N-haloamines are water disinfection byproducts resulting from reactions between dissolved organic nitrogen and disinfectants. N-halogenated peptides, an important group of organic N-haloamines, have been overlooked over the past. In this review, we highlight peptides as the precursors for N-halogenated peptides during wastewater and drinking water disinfection. We discuss the analysis of N ...

- Abstract:
- ... Microplastics (MP) provide a unique and extensive surface for microbial colonization in aquatic ecosystems. The formation of microorganism-microplastic complexes, such as biofilms, maximizes the degradation of organic matter and horizontal gene transfer. In this context, MP affect the structure and function of microbial communities, which in turn render the physical and chemical fate of MP. This n ...

Different dispersion approaches have been used within this technique to allow a close contact between the sorbent and the donor sample solution during the entrapping step, but also between the sorbent and the solvent in the elution step. This ...

- Abstract:
- ... Immunochromatographic strip (ICTS) nanosensors are one of the most popular point-of-care (POC) diagnostic devices currently available for rapid target screening. However, the widely used ICTS sensors based on 20–40 nm gold nanoparticles (AuNPs) as labels are limited by their low detection sensitivity due to their relatively weak color intensity. Moreover, the ever-increasing demand for high sensit ...

- Abstract:
- ... Liquid-phase microextraction is a miniaturized form of traditional liquid–liquid extraction in which the extracting organic phase is limited to a few microliters for extraction of target analytes. Despite the advantages of solid-phase microextraction, liquid-phase microextraction was also rapidly become a popular method due to its unique characteristics. Different liquid-phase microextraction syst ...

Associated with a high production and single use nature of several products, small plastic particles became ubiquitous. Due to processes like water currents and winds, plastics may occur far from their place of origin and affect biota at different environmental compartments. In the environment plastics can degrade int ...

Natural toxins can be classified according to their origin into biotoxins produced by microorganisms (fungal biotoxins or mycotoxins, algal and bacterial toxins), plant toxins or phytotoxins and animal toxins. Biotoxins are generated to protect organisms from external agents also in the act of predation. Among the different groups, bacterial toxins, mycotoxins and phytotoxins can produce damages i ...
