Dissolved organic carbon (DOC) was collected in six rivers that transect the coastal plain of Georgia in July 1999 and February 2000. DOC concentrations ranged from 4.9 to 40.7 g m-3 and from 7.1 to 40.5 g m-3, respectively. The absorption coefficien

The strategy to screen compounds solely for pharmacological potency and selectivity in the early stages of drug discovery brought the pharmaceutical industry to face the stark reality of disproportionate attrition later in the development stage due t

A transect of the St Marys River estuary from above the point of maximum salt wedge penetration to coastal salinities was conducted in July 1999. None of the parameters examined—dissolved organic carbon (DOC) content, UV light absorbance at 254 nm,

Natural organic matter (NOM) was isolated by reverse osmosis from two surface waters of differing climatic regimes and organic source material, in Norway and Georgia, USA. The NOM was separated into methodologically defined size fractions by ultrafil

We examined the utility of five measures of salt marsh function, focusing on angiosperms and microbes, as potential indicators of salt marsh health. We studied twelve salt marsh creeks around Charleston Harbor, South Carolina, USA, six of which were

The reduction in light emission of the marine bacterium Vibrio fischeri used in the standard Microtox® bioassay was measured for the metals copper and mercury. The concentration at which the light emission was reduced by 50% (EC50) was determined to
