Summary: Contaminants of emerging concern (CECs) refer to chemicals or materials that are not currently regulated but are causing growing concerns due to their potential threat to human and environmental health, primarily from wastewater. This study provides an overview of the use of biomass-based sorbents for the removal of CECs from water, highlighting their cost-effectiveness and environmental friendliness. Various forms of biosorbents and their efficiency in removing different CECs are discussed, with biochar-based sorption being the most frequently studied. The review also identifies the need for further research on the commercial application of biosorbents and suggests exploring the use of spent biosorbents in circular systems.

Summary: Excessive plastic use leads to ingestion by organisms, including humans. Microplastics in the human body pose serious health risks and the digestion process alters the properties of plastics, releasing micro- and nanostructures into the environment. These structures can become accidental food sources for aquatic organisms and humans, posing a threat to the environment and human health.

Summary: The presence of toxic dyes in water threatens environmental safety, making efficient removal of dyes from wastewater highly desired. This study successfully fabricated efficient biosorbents through a simple gelation process of sodium alginate and carboxymethyl chitosan in an acidic aqueous solution. The resulting hydrogel beads showed excellent water absorption properties, pH-responsive swelling characteristics, and high methylene blue (MB) adsorption capacity, comparable to existing lignocellulosic and alginate-based hydrogels. The adsorption mechanism was explained by strong electrostatic forces. This research provides a promising and sustainable approach to dye decontamination.

Summary: Emerging contaminants (ECs), relatively low-concentration but high-toxicity pollutants in the environment, have attracted widespread attention in recent years. Biochar, as a low-cost and high-efficiency adsorbent, has been used to treat ECs in water. There are numerous reports on the removal of ECs from water by modified biochar.

Summary: This study investigated the impact of biofilms on the adsorption of emerging contaminants (ECs) on microplastics (MPs). The results showed that most compounds had lower concentrations on biofilm-attached MPs compared to biofilm-absent MPs, indicating that biofilms weaken the adsorption of ECs. Pseudo-equilibrium was achieved within 72 hours, suggesting that ECs have rapid adsorption on biofilm-attached MPs. The partition coefficients were positively correlated with octanol/water partition coefficients, indicating that the adsorption of compounds on MPs is determined by their chemical properties.

Summary: The use of adsorbents like chitosan and cellulose for removing toxic metal ions from water is well-known. By incorporating thiols as metal chelating agents, the sorption behavior of these materials can be significantly improved. Various chemical modification strategies, such as mercaptans, xanthates and dithiocarbamates, are applicable for thiolation of chitosan and cellulose, leading to enhanced metal removal and detection capabilities.

Summary: This study examines the colonization of microorganisms on polyethylene microplastics and their ability to accumulate organic pollutants, as well as the impact of pollutants on biofilm development. The results show that Pseudomonas aeruginosa can form strong biofilms on microplastics, with fluorescent blue microplastics having the highest protein content. The presence of organic contaminants decreases cell viability on white microplastics, while the overall effect on biofilm formation is negligible. Microbial colonization influences the ability of microplastics to accumulate contaminants, with fluorescent blue microplastics showing the highest sorption capacity.

Summary: This study characterized the chemical composition of brewer's spent yeast (BSY) from two different beer productions and tested its cytotoxicity in various cell lineages. The results showed that BSY samples had similar lipid and ash content but slight differences in other nutritional components. BSY2 sample had higher concentrations of glucans and phenolic compounds. Both BSY1 and BSY2 extracts demonstrated similar antioxidant capacity and were not cytotoxic to most cell lines except PANC-1 cells. These findings suggest that brewery residue can be a value-added functional food with potential adjuvant role against PANC-1 cell lines.

Summary: The rise in consumption of ultra-processed meat and dietary collagen supplements poses a challenge to food quality control. This study aimed to develop a new method using cyclodextrin-assisted electrokinetic chromatography with indirect UV detection to determine 4-hydroxyproline for collagen monitoring in dietary supplements and meat products. The method involved hydrolyzing samples with sulfuric acid and removing them using simultaneous neutralization/precipitation reactions with strontium carbonate. The method was successfully validated and proved to be a feasible alternative for quality control.
