Pollution characteristics, risk assessment, and environmental associations of microplastics and antibiotic resistance genes in tropical marine aquaculture: A comparative study across different farming systems in Hainan.
Microplastics (MPs) and antibiotic resistance genes (ARGs) were compared across four marine aquaculture systems in Hainan (fish, shrimp, fish-shrimp mixed, and snail farms). MPs averaged 4.90 ± 5.50 items·L-1, with polyethylene, rayon, polypropylene-polyethylene copolymer, and polystyrene as dominant polymers. Fibers (...
