Description

2,4,2',4'-Tetrachlorobiphenyl (PCB 52) is a persistent organic pollutant (POP) and a highly toxic congener of polychlorinated biphenyls (PCBs). It has been widely used as a dielectric fluid in transformers and capacitors, as well as in hydraulic fluids, plasticizers, and flame retardants. PCB 52 is a persistent environmental contaminant that can accumulate in the food chain. It has been linked to various adverse health effects in humans and wildlife, including cancer, reproductive problems, and developmental disorders. Extensive research has focused on understanding the environmental fate, toxicity, and metabolism of PCBs, including PCB 52. This compound is frequently studied due to its ubiquitous presence in the environment, its potential for bioaccumulation, and its significant toxicity. Understanding its properties is crucial for managing its risks and mitigating its environmental impacts.'

Research Excerpts

Toxicity

ExcerptReferenceRelevance
" The objective of the present study was to determine the toxic effects of 2,4,2',4'-tetrabromodiphenyl ether (BDE 47) on the growth of the marine diatom Skeletonema costatum and on the parthogenetic reproduction and filtering activity of the freshwater crustacean Daphnia magna."( Chronic toxicity of 2,4,2',4'-tetrabromodiphenyl ether on the marine alga Skeletonema costatum and the crustacean Daphnia magna.

Dosage Studied

The birds were dosed orally with the PCB mixture, Aroclor 1242, or the individual PCB isomers, 2,4,2',4'-tetrachlorobiphenyl (2-TCB), and were killed 48 h later. These pregnant rats were injected daily with either 2, 4, 3, 4'-T'-T' (PCB 77) at the dosage of 1 or 20 mg/kg body weight.
