Acute toxicity of 4-nitrophenol, 2,4-dinitrophenol, terbufos and trichlorfon to grass shrimp (Palaemonetes spp.) and sheepshead minnows (Cyprinodon variegatus) as affected by salinity and temperature Acute toxicity of 4-nitrophenol, 2,4-dinitrophenol, terbufos and trichlorfon to grass shrimp (Palaemonetes spp.) and sheepshead minnows (Cyprinodon variegatus) as affected by salinity and temperature
The toxicities of two industrial chemicals (4-nitrophenol and 2,4-dinitrophenol) and two organophosphate insecticides (terbufos and trichlorfon) to juvenile grass shrimp (Palaemonetes spp.) and sheepshead minnows (Cyprinodon vanegatus) were determined by static, 96-h toxicity tests in a factorial design with 12 combinations of salinity and temperature (15, 20, 25, 30ppt x 17, 22, 27°C)

Quantifying precision of in situ length and weight measurements of fish Quantifying precision of in situ length and weight measurements of fish
We estimated and compared errors in field-made (in situ) measurements of lengths and weights of fish. We made three measurements of length and weight on each of 33 common carp Cyprinus carpio, and on each of a total of 34 bluegills Lepomis macrochirus and black crappies Pomoxis nigromaculatus. Maximum total lengths of all fish were measured to the nearest 1 mm on a conventional measuring...

Synopsis of discussion session on physicochemical factors affecting toxicity Synopsis of discussion session on physicochemical factors affecting toxicity
The paper documents the workshop discussion regarding the role of these factors in altering toxicity. For each factor, the nature, magnitude, and uncertainty of its empirical relation to the toxicity of various chemicals or chemical classes is discussed. Limitations in the empirical database regarding the variety of species and endpoints tested were addressed. Possible mechanisms...

Liquid-chromatographic determination of sarafloxacin residues in channel catfish muscle-tissue Liquid-chromatographic determination of sarafloxacin residues in channel catfish muscle-tissue
A liquid chromatographic method is described for the determination of sarafloxacin hydrochloride residues in channel catfish (Ictalurus punctatus) fillets. Sarafloxacin was extracted from fillet tissue with acetonitrile–water (1+1). The extract was centrifuged and the supernatant was partitioned with hexane. The aqueous fraction was filtered through a 0.45 μm filter and evaporated to...

Environmental contaminants in redheads wintering in coastal Louisiana and Texas Environmental contaminants in redheads wintering in coastal Louisiana and Texas
Whole body and liver analyses indicated that wintering redheads (Aythya americana; n = 70) in coastal Louisiana (one site) and Texas (two sites) were relatively free of contamination with common trace elements, organochlorines, and hydrocarbons. Most trace elements, including As, Cr, Hg, Mg, Mn, Ni, Pb, Se, Sr, and Zn, were within background concentrations in livers; levels of B, Cd, Cu...

Water resources of the Menominee Indian Reservation of Wisconsin Water resources of the Menominee Indian Reservation of Wisconsin
Water resources of the Menominee Indian Reservation, Wisconsin, were investigated during the period October 1981 through September 1987. The report presents baseline data and some interpretation of ground- and surface-water hydrology and quality of the Reservation. The area stratigraphy consists of basal Precambrian crystalline bedrock and overlying till and sand and gravel deposits. In...

Growth and mortality of larval sunfish in backwaters of the upper Mississippi River Growth and mortality of larval sunfish in backwaters of the upper Mississippi River
We estimated the growth and mortality of larval sunfish Lepomis spp. in backwater habitats of the upper Mississippi River with an otolith‐based method and a length‐based method. Fish were sampled with plankton nets at one station in Navigation Pools 8 and 14 in 1989 and at two stations in Pool 8 in 1990. For both methods, growth was modeled with an exponential equation, and instantaneous...

Biomonitoring environmental contamination with pipping black-crowned night heron embryos: Induction of cytochrome P450 Biomonitoring environmental contamination with pipping black-crowned night heron embryos: Induction of cytochrome P450
Cytochrome P450-associated monooxygenase activities and cytochrome P450 proteins were measured in pipping black-crowned night heron (Nycticorax nycticorax) embryos collected from a reference site (next to the Chincoteague National Wildlife Refuge, VA) and three polluted sites (Cat Island, Green Bay, Lake Michigan, WI; Bair Island, San Francisco Bay, CA; West Marin Island, San Francisco...
