| 520 | |a"The Bay of Quinte, Lake Ontario, has been identified by the International Joint Commission (IJC) as an Area of Concern. The many municipal, industrial and recreational uses have been severely impaired for many years. Cultural eutrophication since the early 1800s has been severe. Here, chronologically-dated sections of sediment core collected from the Bay of Quinte describe the decline in water quality from the oligotrophy of precolonial times to the hypereutrophy of today. Increased inputs of phosphorus and sulfur have combined to generate sulfide ion in the anoxic sediments, the action of which is to mobilize phosphorus. Most of the available phosphorus is contained within the top 6 cm of the sediment column; depletion of this pool of available P will take at least 10 years even if no more phosphorus enters the Bay"--Management Perspective. |
