In this study, six common TCMs (<em>Persicae Semen</em>, <em>Carthami Flos</em>, <em>Rehmanniae Radix</em>, <em>Angelicae Sinensis Radix</em>, <em>Chuanxiong Rhizoma</em>, and <em>Paeoniae Radix Alba</em>) were collected from various regions across China.

The results showed that Hg in some batches exceeded safety limits. Transfer rates of heavy metal(loid)s from medicinal materials to the decoctions varied considerably among elements, ranging from 8.67 % to 65.56 %. Compared with single-herb decoctions, the dissolution of Cu, Pb, and Cd increased in the compound decoction, whereas that Hg decreased. Probabilistic risk assessment indicated no significant non-carcinogenic risk; however, <em>Paeoniae Radix Alba</em> showed a 1.12 % probability of carcinogenic risk above the 1 × 10<sup>−4</sup> threshold.

We present an explainable QSAR framework that predicts urinary tract toxicity of defined chemicals using mechanistically relevant 2D molecular descriptors. A curated set of 209 structurally diverse compounds was annotated by dose-based EPA LD<sub>50</sub> thresholds, ensuring toxicological relevance and chemical definition. Following rigorous preprocessing, 1444 descriptors were reduced to 11 variables capturing polarity, hydrogen-bonding capacity, and charge distribution. Twelve machine-learning algorithms were evaluated, and Random Forest performed best (accuracy = 84.13 %, AUC = 0.86). SHAP analyses provided global and compound-level explanations, implicating descriptor patterns consistent with epithelial barrier disruption, oxidative stress, and altered membrane permeability as drivers of toxicity. External test performance and applicability-domain assessment supported robust generalization across chemical space, with performance metrics comparable to those reported for earlier urinary and renal toxicity models. This work provides a transparent <em>in silico</em> tool for early safety evaluation that complements existing approaches by emphasizing mechanistic interpretability, supporting risk assessment for chemicals in the human environment, and fostering 3Rs by reducing reliance on animal testing.

Compared with the control group, exposure to PS-NPs resulted in no significant change in serum cholesterol levels but a marked reduction in testicular and TM3 cell cholesterol levels. Western blot analysis revealed prepubertal PS-NPs exposure activated the PPARα pathway, with a consequent significant downregulation in the expression of cholesterol uptake receptors SCARB1 and LDLR. Using immunoprecipitation, we found that PS-NPs disrupted cholesterol uptake by facilitating the ubiquitin-dependent degradation of FTO.
