Polychlorinated biphenyl spatial patterns in San Francisco Bay forage fish.
Industrialized waterways frequently contain nearshore hotspots of legacy polychlorinated biphenyl (PCB) contamination, with uncertain contribution to aquatic food web contamination. We evaluated the utility of estuarine forage fish as biosentinel indicators of local PCB contamination across multiple nearshore sites in San Francisco Bay. Topsmelt (Atherinops affinis) or Mississippi silverside (M...
متن کاملKinetics of polychlorinated biphenyl dechlorination and growth of dechlorinating microorganisms.
The present study has investigated a correlation between the kinetics of polychlorinated biphenyl (PCB) dechlorination and the growth of dechlorinating microbial populations. Microorganisms were eluted from Aroclor 1248-contaminated St. Lawrence River (NY, USA) sediments and inoculated into clean sediments spiked with Aroclor 1248 at 10 concentrations ranging from 0 to 3.12 micromol/g sediment ...
متن کاملAerobic Polychlorinated Biphenyl-Degrading Bacteria
Several bacterial isolates were characterized based on their abilities to degrade specific polychlorinated biphenyls (PCBs) and their 16s rRNA gene sequences. The members of one group of bacteria consisting of Alcaligenes species, including the PCB-degrading bacterium Alcaligenes eutrophus H850, had strong abilities to degrade a broad range of PCBs but not the di-para-chlorine-substituted conge...
متن کاملidentification of aerobic polychlorinated biphenyl degrading bacteria
background: polychlorinated biphenyls (pcbs) are synthetic aromatic compounds containing two benzene rings with one to ten chlorine atoms. there are concerns about the health risks of these compounds in the environment due to their toxicity, persistence, and biological accumulation. pcbs wastes must be treated before being discharged to the environment because they will pollute the water, soil,...

Phurmacol. 2-8, 189-199, Aroclor 1242, a commercial polychlorinated biphenyl (PCB) mixture, was administered ip to rats for 10 weeks. Principal findings included: loss of body weight; hepatic and renal damage, with some animals exhibiting renal ...
