The levels of cortisol, ERs, and VTG
increased in FW (Figure 5), supporting the findings of previous studies (Rayner and Trayhum, 2001; Nagasaka et al.
We documented a significant induction of vtg
in male fathead minnows after a 21-d exposure to the MWPCF effluent.

, female 11KT values were elevated during the nonspawning season, October through March.
concentrations measured in plasma samples were similar to those found in other wastewater effluent evaluations in Europe and the United States.
Body plethysmograph measurements for VTG
or FRC are always slightly higher than normal becasue esophageal volume is included in the measurement.
Specializing in delivering reliable, scalable and configurable responses in support of our customers' telecommunications and security requirements enables VTG

2] at a concentration of 10 ng/L, which has previously been found to induce a maximum VTG
response (Panter et al.
Maternal transfer of EDCs may also occur in fish, when pollutants are co-transported with VTG
into the developing oocyte (Gray et al.
To confirm that white perch are being exposed to estrogenic substances, plasma was collected from adult white perch from Cootes Paradise and analyzed for the presence of the egg yolk protein VTG
4 [micro]g/L treatment, 80% of the females had VtG
oocytes and 20% were at the postovulatory or spawning stage.

and choriogenin proteins.
Engineered to improve fuel economy and reduce emissions, BorgWarner s VTG
turbochargers boost the performance of the 55 kW (75 PS) and 66 kW (90 PS) diesel engines.
