Polychlorinated biphenyl (PCB) biomagnification was characterized in a harbor seal food web in the Strait of Georgia, British Columbia, Canada.

Accumulation of polychlorinated biphenyls from contaminated sediment by Atlantic cod (Gadus morhua): Direct accumulation from resuspended sediment and dietary accumulation via the polychaete Nereis virens

pages 2472–2481
Anders Ruus, Ingrid Aarre Daae and Ketil Hylland

Bioaccumulation of sediment-associated polychlorinated biphenyls (PCBs) was examined in Atlantic cod (Gadus morhua) through direct diffusion from the sediment (via the water phase) and through the food chain (dietary exposure).

Methylsulfonyl polychlorinated biphenyls in fish from an electronic waste-recycling site in South China: Levels, congener profiles, and chiral signatures

pages 2507–2512

Great concerns have been raised about the fate and effects of polychlorinated biphenyls (PCBs) and other organic contaminants contained in electronic waste (e-waste) exported from industrialized countries at midlatitudes to subtropical and tropical regions. In the present study, 17 MeSO₂-PCBs, including five chiral congeners, were detected in the muscle, liver, and brain tissues of two benthic fish species—northern snakehead and mud carp—from a small pond near an electronic waste recycling site in South China.

Incidence of jaw lesions and activity and gene expression of hepatic P4501A enzymes in mink (Mustela vison) exposed to dietary 2,3,7,8-tetrachlorodibenzo-p-dioxin, 2,3,7,8-tetrachlorodibenzofuran, and 2,3,4,7,8-pentachlorodibenzofuran

pages 2545–2556

This study assessed the effects of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), 2,3,4,7,8-pentachlorodibenzofuran (PeCDF), and 2,3,7,8 tetrachlorodibenzofuran (TCDF) on the incidence of jaw lesions and on hepatic cytochrome P4501A (CYP1A) endpoints in mink (Mustela vison).

Distinct mechanisms of endocrine disruption of DDT-related pesticides toward estrogen receptor α and estrogen-related receptor γ

(pages 2597–2605)
Shulin Zhuang, Jing Zhang, Yuezhong Wen, Chunlong Zhang and Weiping Liu

Molecular dynamics (MD) simulations were applied to probe the molecular recognition process of DDT and its five analogs, including dichlordiphenyldichloroethylene (DDE), dichlorodiphenyldichloroethane (DDD), methoxychlor (MXC), p,p′-hydroxy-DDT (HPTE), and dicofol by human estrogen receptor (ER) α and human ER-related receptor (ERR) γ.
