Cold-vapor atomic absorption analysis for mercury in the Greenland Sea

The effects of low metal levels on a clonal hydroid

“…Shaw (1954) and others found, using enzymes and a range of organisms from protozoa to fish, that the toxicity of metals always follows this sequence. Author Hosohara et al 1961Carr et al 1974Hosohara, 1961Fitzgerald et al 1974Carr et al 1972Smith et al 1971Fitzgerald & Lyons, 1973Chester et al 1973Leatherland et al 1973Chester et al 1973Chester et al 1973Chester et al 1973Gardner, 1975Gardner, 1975Gardner, 1975Gardner, 1975Gardner, 1975Gardner, 1975Leatherland et al 1971 Gardner & Jones, in his studies with Gasterosteus (1939) and Polycelis (1940) appears to have initiated the search for physicochemical characteristics of metals that correlate with their toxic effects upon aquatic organisms. He found that toxicity increased with the standard electrode potential ('solution pressure') of the metal.…”

Mercury. Short-term storage of natural waters

“…The plots show mercury in the acidified sample to be initially associated with the filterable solids but entering the solution phase as time proceeds. Purging of an aliquot at to + 96 hr, using the conditions previously developed for flameless atomic absorption (Carr et al, 1972), showed quantitative removal of the tracer and gave an faas value of 20 ± 3 ng/1. Whole bottle counting after eight days indicated 0.7% of the tracer had adhered to the container.…”

Improvement in cold vapor atomic absorption determination of mercury

“…Determination of residual mercury in natural water is a particular problem because mercury levels in natural water are often 0.03-0.06 ppb or lower and tedious preconcentration procedures are necessary (5)(6)(7)(8)(9). These facts indicate the need for a more sensitive instrument for the direct determination of mercury in natural waters.…”
