Abstract:

Cyanobacterial blooms and their toxins are a major water quality and potential health risk around the world. This thesis developed an analytical method for microcystin congeners in sediments in order to examine their fate in lakes and establish the history of toxin-producing cyanobacteria in relation to environmental change using lake sediments. A novel method for both intra- and extracellular microcystins in lake sediments was developed, consisting of accelerated solvent extraction, hydrophilic-lipophilic balance solid phase extraction and multiple reaction monitoring-based HPLC-MS/MS quantit

Abstract:

This work explores the fragility of the Great Lakes and the environmental degradation we have caused. My main focus revolves around what the EPA considers to be the Great Lakes Areas of Concern (AOCs). This list contains 27 rivers that flow into the Great Lakes, most of which are or have been areas of industrial and chemical pollution. Through installations involving photography, ceramics, and video, I hope to reveal the issues facing the Great Lakes and explore how people can help.

Approximately 14,500 years ago, Pleistocene Lake Bonneville discharged 4750 km 3 of water over the divide between the closed Bonneville Basin and the watershed of the Snake River.

For the 1100 kilometers between Red Rock Pass and Lewiston, Idaho, the Bonneville Flood left a spectacular array of flood features that have allowed for geologic reconstruction and quantitative evaluation of many a

Aerobic methanotrophs (MOB) are a functional group of proteobacteria that use methane as their only energy and carbon source. Phylogenetically, such methanotrophs are affiliated with present alpha and gamma proteobacteria. Methanotrophic microorganisms play an essential role in the methane cycle, since they to a great extent reduce potential methane emissions to the atmosphere. In stratified lakes the aerobic methanotrophs are commonly present at the oxic-anoxic interfaces.

Research concerning the detection and distribution of the lakes are then discussed. Features of the lakes such as surface areas, chemical compositions and formations like shores are looked into.

Coastal and shallow lakes are often subjected to eutrophication due to nutrients from catchment farming activities. Lake Ellesmere (Te Waihora) is a hyper-eutrophic lake which has gained recent attention because of concerns over its ecological health and fishery status.

Eight littoral sites were sampled on a single occasion, and 20 benthic sites were sampled once per season for one year.

Lake restoration and management strategies focus on reducing the negative impacts of enriched or polluted inflows. These strategies become of paramount importance when lakes are used for recreational and/or drinking water purposes. Long term control of eutrophication and turbidity problems associated with large inflow loads is usually oriented to catchment management. Although it has been suggested that this is the correct long term approach, public concerns usually require a short term solution. In addition, due to political and economic costs related to changes in catchment management, in-la

One of the practices for dealing with water pollution from point and non point pollution sources is the use of on-line purification lakes. The Lea Marston lakes were built in the early 1980' s to reduce the pollution load transported by the River Tame to the River Trent. The lakes operate on the principle of particle bound contaminant sedimentation. The lakes were observed to be efficient at reducing suppressed (ATU) biochemical oxygen demand (BOD(ATU)), suspended solids (SS) and metals under dry weather flow and wet weather flow conditions.
