Diagnostic brain residues of dieldrin: Some new insights
G. H. Heinz, R.W. Johnson
D.W. Lamb, E.E. Kenaga, editor(s)
1981, Book chapter, Avian and Mammalian Wildlife Toxicology, Second Conference: a symposium
Forty adult male cowbirds were fed a diet containing 20 ppm dieldrin; 20 of the birds were randomly selected to die from dieldrin poisoning and 20 were sacrificed when dieldrin had made them too sick to eat. An average of 6.8 ppm dieldrin (range of 1.51 to 11.7) in the...
Reproductive tests of diazinon on bobwhite quail
K. L. Stromborg
D.W. Lamb, E.E. Kenaga, editor(s)
1981, Book chapter, Avian and Mammalian Wildlife Toxicology: Second Conference
Diazinon was fed at sublethal levels to reproductively active bobwhite (Colinus virginianus). Thirty pairs were given constant concentrations (0, 35. 50, 72, 104, or 150 ppm) for 3 weeks (Constant group). Another 30 pairs (Pair-fed group) were matched to these by body weights and were fed the amounts of untreated...
Formalin preservation of avian blood for organochlorine analysis
C. J. Stafford, W. H. Stickel
D.W. Lamb, E.E. Kenaga, editor(s)
1981, Book chapter, Avian and Mammalian Wildlife Toxicology: Second Conference
Blood biopsy for chemical analysis is a valuable technique for evaluating chemical exposure of birds in the wild without harming the birds. Field conditions, however, often make sample storage difficult. Better methods than freezing are needed to improve the interpretive value of chemical analysis of the sample....
Inorganic and organic mercury chloride toxicity to Coturnix: sensitivity related to age and quantal assessment of physiologic responses
E. F. Hill
1981, Book
The toxicities of mercuric chloride (HgCl(,2)) and methylmercuric chloride (CH(,3)HgCl) were compared for coturnix (Coturnix coturnix japonica) from hatching to adulthood. Comparisons were based on: (1) Median lethal dosages (LD50) derived by administering single peroral and single intramuscular dosages of mercury, (2) median lethal concentrations (LC50) derived by feeding mercury...
Map accuracy
U.S. Geological Survey
1981, Report
An inaccurate map is not a reliable map. "X" may mark the spot where the treasure is buried, but unless the seeker can locate "X" in relation to known landmarks or positions, the map is not very useful....
APSRS state-base graphics
Water Resources Division, U.S. Geological Survey
1981, Report
The National Cartographic Information Center (NCIC) is the information branch of the U.S. Geological Survey's National Mapping Division. In order to organize and distribute information about U.S. aerial photography coverage and to help eliminate aerial mapping duplication by tracking individual aerial projects, NCIC developed the Aerial Photography Summary Record System...
