Toxicity of Abate to green frog tadpoles Toxicity of Abate to green frog tadpoles
Green frog tadpoles were exposed to a 96hr toxicity test using Abate4E, the formulation for temephos used in mosquito control. Concentrations ranged from 0 (control) to 10 uL/L. Concentrations as low as 2.60 uL/L reduced activity for several hours after exposure but had negligible effects after 24 hr, presumably because the temephos had degraded during that time. The LC50 for Abate was 4...

Toxicity of alkalinity to Hyalella azteca Toxicity of alkalinity to Hyalella azteca
Toxicity testing and chemical analyses of sediment pore water have been suggested for use in sediment quality assessments and sediment toxicity identification evaluations. However, caution should be exercised in interpreting pore-water chemistry and toxicity due to inherent chemical characteristics and confounding relationships. High concentrations of alkalinity, which are typical of...

Reinterpretation of the peninsular Florida Oligocene: An integrated stratigraphic approach Reinterpretation of the peninsular Florida Oligocene: An integrated stratigraphic approach
A very thick (> 300 m) nearly continuous Oligocene section exists in southern peninsular Florida, as revealed by lithostratigraphic, biostratigraphic (mollusks and dinocysts), chronostratigraphic (Sr isotopes) and petrographic analyses of twelve cores and two quarries. The Oligocene deposits in the subsurface of southern Florida are the thickest documented in the southeastern U.S., and...

Continuous monitoring of dissolved oxygen and total dissolved gas pressure based on head-space partial pressures Continuous monitoring of dissolved oxygen and total dissolved gas pressure based on head-space partial pressures
We describe an instrument prototype that measures total dissolved gas pressure (TGP) and dissolved oxygen (DO) without need for standard wetted probe membranes or gas permeable tubing. Measurements were based instead on gas-phase partial pressures that develop within the head-space of a pressure vessel, and on Henry's Law. Performance trials established that differences between standard

Infectious pancreatic necrosis virus in the environment: Relationship to effluent from aquaculture facilities Infectious pancreatic necrosis virus in the environment: Relationship to effluent from aquaculture facilities
Effluents from three fish hatcheries were monitored for the discharge and subsequent downstream distribution of infectious pancreatic necrosis virus (IPNV). Samples of springwater and surface water, and tissues from salmonid and non-salmonid fish were assayed for IPNV. Water samples were processed to recover virus by adsorption to an electropositive, microporous filter matrix. No IPNV...
