What does this research mean for the field?

The co-existence of polyethylene terephthalate microplastics (PET MPs) and nonylphenol ethoxylate (NPE) exhibits a combined effect that significantly enhances binding affinity to bovine serum albumin (BSA), triggering pronounced conformational changes and suppressing protein function more than either component alone. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

Investigate the adsorption mechanism between polyethylene terephthalate microplastics and nonylphenol ethoxylate, and assess the subsequent structural and functional impact of their complex on bovine serum albumin.

Implication

In vitro study reveals combined PET microplastics and nonylphenol ethoxylates disrupt bovine serum albumin structure and function, indicating heightened toxicity through carrier mechanisms.

Key Points

Investigate the adsorption mechanism between polyethylene terephthalate microplastics and nonylphenol ethoxylate, and assess the subsequent structural and functional impact of their complex on bovine serum albumin.
Evaluated PET microplastic adsorption kinetics, thermodynamics, and desorption of nonylphenol ethoxylates under varying pH conditions.
Used multispectral analysis to determine binding site locations, binding affinity, secondary structure changes, esterase-like activity, and thiol content in bovine serum albumin.
PET microplastics adsorbed nonylphenol ethoxylates via spontaneous, endothermic processes fitted to pseudo-second-order (R2 = 0.9985) and Freundlich models (R2 = 0.9241), reaching a 59.29% desorption rate at pH 1.2.
Co-exposure increased binding affinity to Site II of bovine serum albumin (Kb shifted from 5.39 × 104 M−1 to 2.71 × 105 M−1), inducing stronger secondary structure disruption, altered thiol levels, and suppressed esterase-like activity compared to single-compound exposures.
