Occupational exposure to polychlorinated biphenyls (PCBs) in workers at companies in the Colombian electricity sector.

Polychlorinated biphenyls (PCBs) comprise a family of 209 congeners that have low electrical conductivity and high thermal resistance due to their physicochemical properties and are thus widely used as dielectric oils, among other applications. Although PCBs are no longer used in dielectric oils in Colombia as of several years ago, electric transformers in Colombia might still contain PCBs, and workers might carry PCBs due to exposure from when they were still used in dielectric fluid. Thus, occupational exposure in Colombia to PCBs was evaluated by determining their concentrations in the blood plasma samples of 115 workers in the electricity sector . The sum of the six PCB indicators was between
