| Words: 250 | Submitted: 24-Jan-2010 DescriptionTitration of an Eggshell (back titration)During the 1960’s and 70’s the United States extensively used a pesticide called DDT. Unfortunately, this pesticide found its way into rivers and lakes and eventually into wildlife birds of prey such as the Bald Eagle. Wildlife biologists noticed that the eagle eggs were so thin that they would break when the birds were hatching the eggs. As a result, the Bald Eagle population plummeted in the 1970’s to the point that there were estimated to be only 400 mating pairs of eagles in all of the lower 48 states. This was thought to be due to the widespread use of DDT. DDT was then banned for use and the Bald Eagle is no longer on the endangered species list.
