Adsorption behaviors of triclosan by non-biodegradable and biodegradable microplastics: Kinetics and mechanism
AI summary Read the abstract
This study assessed microplastic ingestion by seven seabird species in the North Atlantic, finding plastic in the stomach contents of 87% of individuals. Procellariform birds had the highest ingestion rates, consistent with their foraging behavior near the sea surface.
Microplastics (MPs) pollution has been becoming serious and widespread in the global environment. Although MPs have been identified as vectors for contaminants, adsorption and desorption behaviors of chemicals with non-biodegradable and biodegradable MPs during the aging process is limited. In this work, the adsorption behaviors of triclosan (TCS) by non-biodegradable polyethylene (PE) and polypropylene (PP), and biodegradable polylactic acid (PLA) were investigated. The differences in morphology, chemical structures, crystallization, and hydrophilicity were investigated after the ultraviolet aging process and compared with the virgin MPs. The results show that the water contact angles of the aged MPs were slightly reduced compared with the virgin MPs. The aged MPs exhibited a stronger adsorption capacity for TCS because of the physical and chemical changes in MPs. The virgin biodegradable PLA had a larger adsorption capacity than the non-biodegradable PE and PP. The adsorption capacity presented the opposite trend after aging. The main adsorption mechanism of MPs relied on hydrophobicity interaction, hydrogen bonding, and electrostatic interaction. The work provides new insights into TCS as hazardous environmental contaminants, which will enhance the vector potential of non-biodegradable and biodegradable MPs.

Prevalência e tipos de plásticos em Albatrozes e Petréis (aves: procellariiformes)
AI summary Read the abstract
Researchers quantified and classified plastic debris in Procellariiformes seabirds — albatrosses and petrels — found on Brazilian beaches, finding plastic ingestion in multiple species. These ocean-going birds are among the most vulnerable to plastic pollution because they feed from the ocean surface where plastics concentrate.
