TEQ Diox+PCB-DL levels ranged from 1.70 to 77.1 pg/g (median: 9.90 pg/g), while PCB-NDL levels spanned from 14.0 to 1620 ng/g (median: 65.5 ng/g). Significant, albeit low, correlations were found: length and weight were negatively correlated, and lipid content was positively correlated, with both contaminants. Multivariable regression confirmed length and lipid percentage as significant predictors, although the models explained a limited proportion of variance (R2: 0.23 and 0.17). Classification-based analyses showed that irregularly contaminated eels were shortToxicsMonitoring of PCDD/Fs and PCBs in European Eels (<i>Anguilla anguilla</i>) from Lake Garda: A Persistent Environmental Concern.PMC12389985N/AArcangeli GDi Millo SAngeletti RBiancotto GGasparini MMancin MDiletti GBontacchio SAngelone BGallocchio FBoscolo Anzoletti ACito FFedrizzi GfalseMonitoring of PCDD/Fs and PCBs in European Eels (<i>Anguilla anguilla</i>) from Lake Garda: A Persistent Environmental Concern.This study investigates the concentrations and patterns of dioxins and dioxin-like PCBs (TEQ Diox+PCB-DL) and non-dioxin-like PCBs (PCB-NDL) in eels from Lake Garda, assessing their relationship with biometric and lipid parameters.
