Synergistic effects of irregular PET microplastics and cadmium on cucumber seedlings revealed by LA-ICP-MS imaging.
Microplastics (MPs) and heavy metals are widespread environmental contaminants. Their co-exposure may pose greater risks to plants than either pollutant alone. Since their toxicity depends on tissue-specific distribution, precise imaging of both in plant tissues is critical for uncovering toxicity mechanisms. In this s...
