Abstract To investigate the adsorption and biodegradation of polycyclic aromatic hydrocarobons in the presence of microplastics, polypropylene-microplastics (MP-PP) and benzo[a]pyrene (BaP) were chosen as research materials. The aim was to explore the adsorption behavior and mechanism of BaP onto MP-PP, as well as its biodegradation pathway mediated by Novosphingobium tardaugens using MP-PP. The interaction and microscopic characteristics among MP-PP, BaP and strains were examined using X-ray photoelectron spectroscopy and Fourier transform infrared spectroscopy. The results indicated that the adsorption of BaP onto MP-PP followed the pseudo-second-order kinetic model with monolayer coverage, and this process was enhanced by higher temperatures. The presence of MP-PP improved the efficiency of BaP degradation. However, the degradation pathway of BaP by Novosphingobium tardaugens remained unaffected by MP-PP and continued to follow the phthalic acid pathway. The interaction among MP-PP, BaP, and strains primarily occurred at the surface, with microplastics PP serving as adsorption carriers. Although Novosphingobium tardaugens could not decompose MP-PP, it could adhere to the PP surface, facilitating growth, and thereby enhancing the degradation process.
