Abstract
This study aimed to assess the occurrence, distribution and dietary risks of seven dl-PCBs (dioxin-like PCBs) in eleven collected fish species from Chenab river, Pakistan. â7dl-PCBs (ng gâ1, wet weight) burden was species-specific and the maximum average concentrations were found in Mastacembelus armatus (5.43), and Rita rita (5.1). Correlation of each dl-PCBs with δ15N%, indicated a food chain accumulation process of these chemicals into Chenab river, Pakistan. Species-specific toxicity of each dl-PCBs (WHO-PCBs TEQ) was calculated and higher values were found in three carnivore fish species i.e., M. armatus (2.5 pg TEQ gâ1), R. rita (2.47 pg TEQ gâ1), Securicola gora (2.98 pg TEQ gâ1) and herbivore fish species i.e., Cirrhinus mrigala (2.44 pg TEQ gâ1). The EDI (Estimated Daily Intake) values in most cases exceeded the WHO benchmark (4 pg WHO-TEQ kgâ1 bw dâ1) evidencing a potential health risk for consumers via fish consumption from Chenab river.
