Environmental contaminant studies by the Patuxent Wildlife Research Center Environmental contaminant studies by the Patuxent Wildlife Research Center

Evaluation of the effects of environmental contaminants on wildlife is geared to interpreting events in the field, especially population effects, and both field and laboratory studies are planned for this purpose; procedures are adapted to specific problems and therefore do not include strict protocols or routine testing. Field evaluations include measurements of cholinesterase...

Comparison of game-farm and wild-strain mallard ducks in accumulation of methylmercury Comparison of game-farm and wild-strain mallard ducks in accumulation of methylmercury

The accumulation of mercury was compared in game-farm and wild-strain mallard ducks fed a diet containing 0.5 ppm mercury in the form of methylmercury dicyandiamide. There were no significant differences between the two strains in levels of mercury that accumulated in blood, kidney, liver, breast muscle, brain, eggs, or ducklings. Mercury levels in blood were significantly correlated...

Methylmercury: Reproductive and behavioral effects on three generations of mallard ducks Methylmercury: Reproductive and behavioral effects on three generations of mallard ducks

Three generations of mallard ducks (Anas platyrhynchos) were fed either a control diet or a diet containing 0.5 ppm mercury in the form of methylmercury. The levels of mercury in adult tissues and eggs remained about the same over 3 generations. The methylmercury diet had no effect on adult weights or weight changes during the reproductive season. Females fed a diet containing 0.5 ppm...

Cholinesterase activity in Japanese quail dusted with carbaryl Cholinesterase activity in Japanese quail dusted with carbaryl

Japanese quail (Coturnix coturnix japonica) were dusted with 5% carbaryl to determine if this topical treatment would alter plasma and brain cholinesterase activities. Within 6 hours after dusting, plasma cholinesterase activity was depressed compared with controls, the depression averaging 20% for females and 27% for males. By 24 hours the cholinesterase activity of females had returned...
