No Significant Risk Levels (nsrls) for the Proposition 65 Carcinogens Benzo[b]fluoranthene, Benzo[j]fluoranthene, Chrysene, Di
The oral cancer potencies of six polycyclic aromatic hydrocarbons (benzo[b]fluoranthene, benzo[j]fluoranthene, chrysene, dibenzo[a,h]pyrene, dibenzo[a,i]pyrene, and 5-methylchrysene) were estimated from cancer dose-response data obtained from animal studies. Potency estimates obtained from newborn mouse intraperitoneal (i.p.) injection studies were converted to oral equivalent potencies. The co...

متن کاملFemtogram detection of explosive nitroaromatics: fluoranthene-based fluorescent chemosensors.
Herein we report a novel fluoranthene-based fluorescent fluorophore 7,10-bis(4-bromophenyl)-8,9-bis[4-(hexyloxy)phenyl]fluoranthene (S(3)) and its remarkable properties in applications of explosive detection. The sensitivity towards the detection of nitroaromatics (NACs) was evaluated through fluorescence quenching in solution, vapor, and contact mode approaches. The contact mode approach using...
متن کاملInfluence of biotransformation on trophic transfer of the PAH, fluoranthene.
The persistence of polycyclic aromatic hydrocarbons (PAHs) in marine sediments may be influenced by benthic invertebrate bioturbation. Through processes such as deposit-feeding and enhancement of microbial metabolic activity PAHs may be remobilized from the sediment compartment, and either transferred to organisms at higher trophic levels or to the overlying water column, both processes inevita...
متن کاملBehavioral avoidance of fluoranthene by fathead minnows (Pimephales promelas).
A monitoring system was used to examine the behavioral response of fathead minnows (Pimephales promelas) to plumes of the polycyclic aromatic hydrocarbon fluoranthene. Previously unexposed fish and fish surviving acute exposure to fluoranthene were presented with three different concentrations of fluoranthene. Both groups of fish avoided fluoranthene. Pre-exposure did not enhance or diminish av...
