Implications of chemical-based effluent regulations in assessing DNA damage in fathead minnows (Pimephales promelas) when exposed to metal plating wastewater.
The application of chemical-based regulation on effluents has limitations because of their diverse chemical components, complicated interactions between contaminants, and the lack of information on the bioavailability of constituents (U.S.EPA 1991). In Korea, like in most developing countries, environmental regulations for the protection of the aquatic biota from discharges are based only on th...
متن کاملGene expression of fathead minnows (Pimephales promelas) exposed to two types of treated municipal wastewater effluents.
Contaminants of emerging concern (CECs) in treated municipal effluents have the potential to adversely impact exposed organisms prompting elevated public concern. Using transcriptomic tools, we investigated changes in gene expression and cellular pathways in the liver of male fathead minnows (Pimephales promelas) exposed to 5% concentrations of full secondary-treated (HTP) or advanced primary-t...
متن کاملOvulation but not milt production is inhibited in fathead minnows (Pimephales promelas) exposed to a reproductively inhibitory pulp mill effluent
BACKGROUND A 5-day fathead minnow (FHM) spawning assay is used by industry to monitor pulp mill effluent quality, with some mill effluents capable of completely inhibiting spawning. The purpose of this report is to characterize the effect of an inhibitory effluent on egg and milt production in FHM. METHODS Eight tanks were treated with an inhibitory effluent while eight were kept with clean w...
متن کاملDetermination of vitellogenin kinetics in male fathead minnows (Pimephales promelas).
A lack of knowledge persists concerning the combination of kinetics on protein and mRNA levels of the most commonly used biomarker for estrogenic influences-vitellogenin (VTG). Consequently, male fathead minnows were exposed to 17alpha-ethinylestradiol (EE(2)) for 35 days, followed by an equally long depuration period in a flow-through system. VTG mRNA levels reached a plateau after 3 days of e...
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...
