In recent decades, the study of heavy metal pollution has garnered significant attention owing to advancement industrialization. To explore contamination metals in an intensive industrial and agricultural region Shandong province, China, 101 surface soil samples 80 edible crop parts were collected from vicinity park. A positive matrix factorization-multilayer perceptron model (PMF-MLP) was established identify sources quantify complex relationships between sources, types, status. Index human health-risk methods used assess pollution. The results show that (1) lead (Pb) cadmium (Cd) may originate industrial-traffic mixed surrounding park, whereas copper (Cu) is derived southern farmland. (2) Pollution primarily concentrated central northern regions area. analysis PMF-MLP indicates activities account for majority (79.6 %) risk associated with Among them, industrial, traffic, livestock farms, types contribute 49.3, 24.5, 5.80 % total risk, respectively.
