Postmenopausal women represent a vulnerable population towards endocrine disruptors due to hormonal deficit. We previously demonstrated that chronic exposure of ovariectomized C57Bl6/J mice fed high-fat, high-sucrose diet low-dose mixture chemicals with one dioxin, polychlorobiphenyl, phthalate, and bisphenol A triggered metabolic alterations in the liver but intestine was not explored. Yet, ga...
The toxicity of polychlorinated biphenyls (PCB) can be efficiently reduced in contaminated marine sediments through the reductive dechlorination (RD) process lead by anaerobic organohalide bacteria. Although the process has been extensively investigated on PCB-spiked sediments, the knowledge on the identity and metabolic potential of PCB-dechlorinating microorganisms in real contaminated matrix...
When microorganisms eluted from upper Hudson River sediment were cultured without any substrate except polychlorobiphenyl (PCB)-free Hudson River sediment, methane formation was the terminal step of the anaerobic food chain. In sediments containing Aroclor 1242, addition of eubacterium-inhibiting antibiotics, which should have directly inhibited fermentative bacteria and thereby should have ind...
BACKGROUND There is conflicting epidemiological evidence concerning an increase in risk of non-Hodgkin's lymphoma (NHL) associated with elevated blood levels of persistent organochlorine (OC) pesticides and polychlorobiphenyls (PCBs). METHODS We measured the concentration of 17 OC pesticides, including hexachlorobenzene (HCB), four lindane isomers (alpha-, beta-, gamma- and delta-hexachlorocy...
Polychlorobiphenyl (PCB) biodegradation was followed for 1 year in microcosms containing marine sediments collected from Mar Piccolo (Taranto, Italy) chronically contaminated by this class of hazardous compounds. The microcosms were performed under strictly anaerobic conditions with or without the addition ofDehalococcoides mccartyi, the main microorganism known to degrade PCBs through the anae...
