Trace metals transported by the Amazon (and Yukon rivers were analytically partitioned among the transport phases: in solutions, ion exchange, organic materials, metallic coatings, and crystalline solids. The distribution for both rivers is similarly proportioned, with copper and chromium transported mainly in the crystalline solids, manganese in coatings,(More)
Samples of Townsville Harbor bottom mud were acid leached (0.3 m HCl) to measure bioavailability of Cd, Co, Cu, Fe, Mn, Ni, Pb, Sn and Zn. Three of seven samples showed enrichment factors relative to average soil of 25-30 for Cd, 5-71 for Cu, 21-81 for Pb, and 13-37 for Zn. The other four samples were only high in Cd, Pb, and Zn by an enrichment factor of(More)
Seven bottom samples extending from the ocean up through Belize Harbor and City were acid leached (EPA method 200.7) and analyzed using inductively coupled plasma spectrometry to measure the bioavailability of Cd, Cr, Cu, Pb and Zn. Soil and environmental chemists would compare data to world averages of unpolluted soils, these samples were higher than this(More)
In the darkness of space, a territorial war ensues. This comical battle is futile. Two species compete to plant the first flag, and the competition escalates to a contest to place the greatest number of flags on a planet and claim it for their home world.
