The bioavailability and toxicity of copper (Cu) in Shelter Island Yacht Basin (SIYB), San Diego, CA, USA, was assessed with simultaneous toxicological, chemical, and modeling approaches. Toxicological measurements included laboratory toxicity testing with Mytilus galloprovincialis (Mediterranean mussel) embryos added to both site water (ambient) and site water spiked with multiple Cu concentrat...

Cochran, H.D., Cummings, P.T. and Karaborni, S., 1992. Solvation in supercritical water. Fluid Phase Equilibria, 71: 1-16. The aim of this work is to determine the solvation structure in supercritical water compared with that in ambient water and in simple supercritical solvents. Molecular dynamics studies have been undertaken of systems that model ionic sodium and chloride, atomic argon, and m...

Lead, arsenic, cadmium, and methyl mercury are nonessential and potentially highly toxic metals. They may be found in minute and variable but measurable amounts in food, drinking water, and/or ambient air. Because each of the metals has been identified as a serious environmental contaminant in various parts of the world, much research effort has been devoted to them, especially during the past ...

In this study, fertilized mirror carp eggs were allowed to develop in fresh water with various magnesium concentrations (0.05, 0.2 and 2 mg l). The percentage of dead (eggs+prelarvae) and deformed prelarvae increased sharply to 94% at an ambient magnesium concentration of 0.05 mg l compared with 22 and 10% at ambient magnesium concentrations of 0.2 mg l and 2.0 mg l, respectively. Mirror carp r...

We tested the hypothesis that birds can rapidly change the conductance of water vapor at the skin surface in response to a changing need for evaporative heat loss. Mourning doves (Zenaida macroura) were placed in a two-compartment chamber separating the head from the rest of the body. The rate of cutaneous evaporation was measured in response to dry ventilatory inflow at three ambient temperatu...

A conventional Ohmeda Intensive Care Incubator was instrumented with an ambient and five wall temperature probes and an ambient humidi ty meter. The infant being monitored was f i t ted with heel and abdominal skin temperature probes and an esophageal probe. An Apple lie microcomputer sampled analog output voltages from these sensors, and components of the metabolic energy balance were calculat...
