Source-oriented probabilistic risk assessment of sediment heavy metal(loid)s in a typical fireworks-production basin with mixed industrial and agricultural influences.
Fireworks production introduces persistent heavy metals and metalloids into river sediments, yet source-specific ecological and health risks under mixed land uses remain unclear. Here, we developed an integrated framework coupling Positive Matrix Factorization (PMF) with Fractional Moment-Maximum Entropy (FM-MEM)-based...
