Great Lakes development

The quality and abundance of Great Lakes basin resources have been the foundation of the region s development since earliest European settlement. Indeed, in a little over a century, the Great Lakes Basin has evolved from a backwoods subsistence economy to a highly geared industrialized society. By way of current example ... 

This paper discusses some of the impacts of development on the Great Lakes. Efforts that have been made to resolve individual problems are also discussed including the unique Canada/U.S. institutional framework for addressing these issues. Emphasis is placed on eutrophication and toxic substances, issues which have been the major focus of concern over the last three decades. 

The nature of human impacts on the Great Lakes relates closely to historical development and land use in the basin which, in turn, relate closely to the geology and physiography of the watershed. The southern part of the basin consists largely of Palaeozoic sedimentary rocks. Land use consists primarily of intense...

Shreier et al. [77] developed an HPLC method for the determination of Bayluscide residues in muscle fillet tissues of fish exposed to Bayluscide and 3-(trifluoro-methyl)-4-nitrophenol during sea lamprey control treatments in the Great Lakes (USA). 

Cheam et al. [128] have developed a Great Lakes reference sediment for selenium. 

Soils very low in available sulfur are common in a number of regions of the world. In the United States, low-sulfur soils are frequently found in the Pacific Northwest and in some parts of the Great Lakes states. For many years, sulfur in the form of calcium sulfate was an accessory part of most commercial phosphate fertilizers, and this probably helped to prevent development of widespread sulfur deficiency in crops grown... 

The test kit is based on immunoassay techniques and the method takes about 10 minutes to provide an analysis. A unique tag, permanently attached to the polymer, changes the color of special test strips exposed to ppm levels of polymer. The strips indicate the amount of tagged polymer that is present, without interference from other additives and contaminants. This technology is not currently available for continuous inhibitor detection, but given the importance of AH Organic Programs, there is little doubt that further developments will take place. The Water Additives Division of Great Lakes Chemical Corp. have also recently introduced a similar simple and accurate immunoassay test for the detection of Belclene 200 antiscalent.
