Distinct toxicity profiles of conventional and biodegradable fishing nets' leachates after artificial aging.

Fishing nets (FNs) represent a significant source of plastic waste, but their contribution to pollution by micro- and nanoplastics (MNPs) and associated additives is poorly understood. We studied the degradation of a high-performance-polyethylene-polypropylene (HPPE-PP) trawl net and two trammel nets made of polyamide 6 (PA6) or biodegradable polybutylene-succinate-polybutyrate-adipate-terephthalate (PBS-PBAT). Accelerated artificial ageing (AA) was performed using UV irradiation under environmental or extreme conditions followed by abrasion in water with glass microbeads.

QuEChERS Approach for the Analysis of Three Fluoroquinolone Antibiotics in Wastewater: Concentration Profiles and Ecological Risk in Two Nigerian Hospital Wastewater Treatment Plants.

Hospital wastewater is regarded as a primary and very important source of antibiotics in the aquatic environment. Studies on the analysis, occurrence, and ecological risk assessment of fluoroquinolone antibiotics in wastewater are still limited in Africa. A quick, easy, cheap, effective, rugged, and safe extraction method was optimized and applied for determination of three fluoroquinolone antibiotics (ciprofloxacin, norfloxacin, and ofloxacin) in wastewater from two Nigerian hospital wastewater treatment plants (WWTPs) and effluent receiving water.
