1	A Study of Certain Organic Compounds of the Bottom Sediments of the Dundas Marsh, Hamilton, Ontario Larner, Elizabeth Anne 09 1900 (has links) In the course of a little over a year, from January, 1950, to March, 1951, core samples of bottom sediments were collected at three different stations in the Dundas Marsh, Hamilton, Ontario. A number of the samples were analysed for total carbon content, bitumen, pectins, hemicelluloses, and cellulose and lignin content. This study is part of a larger investigated by the Department of Zoology to ascertain the relationships between the biological productivity in lakes and the rate of mineralization of the organic detritus in lake bottom sediments. / Thesis / Master of Science (MSc) Dundas Marsh Hamilton Ontario core samples lake bottom sediment total carbon content bitumen pectins hemicelluloses cellulose content lignin content rate of mineralization biological productivity
