Methodology: The water samples will be collected utilizing sterile plastic water bottles from Lake Tarpon. The location the samples will be collected from is Anderson Park, by the boat docks, located at 39669 U.S. 19, Tarpon Springs, FL 34689. The water samples will be brought to Tarpon Springs High School to be tested, located at 1411 Gulf Rd, Tarpon Springs, FL 34689. The phosphate, nitrate, and dissolved oxygen levels will be tested utilizing various LaMotte water testing kits,

This experiment was centered on metabolic and biochemical testing procedures. The rationale of performing these tests was to distinguish six different microbes from one another and to compare how their metabolic and biochemical processes differ from species to species to determine the unknown sample.

The purpose of this experiment was to indirectly study the effects of environmental stress on cell membranes. Watercourses have been with discarding of domestic and manufacturing, for centuries. Alarms have only escalated about the ecological alterations in the recent years of what would be the consequences. Scientists have developed a thorough investigation in search of various man harmful waste that is damaging the environment of watercourses.

A conceptual framework was developed that incorporated characteristics of chemicals, agricultural landscapes, and aquatic ecosystems that interact to influence exposure. From this framework, the workgroups designed a tiered system for the risk assessment process in which the assessment progresses from a deterministic assessment to probabilistic assessments of increasing complexity. Each tier includes several experimental and analytical options that reduce uncertainty and provide more complete descriptions of the aquatic environment (Environmental Proection Agency, 2012).

Fresh cell homogenate of G. semen collected from Lake Jelino (“FH” treatments) with chl-a range: 894 – 3576 mg m-3, caused distinct negative effect on Daphnia survival (Fig. 2.). It increased with the increasing biomass of alga and time of exposure. At lower chl-a concentrations (894 and 1778 mg m-3) the survival rate averaged 40% – 70 % after 24 h and 20 % – 30 % after 48 and 72 h of exposure. However, the addition of the most concentrated and fresh G.semen homogenized biomass (chl-a: 3576 mg m-3) caused 100% Daphnia mortality already after

Bioassays, Daphnia magna, were used to monitor water for the presence of toxic compounds in various water samples, including samples 1 mile upstream from the Fletcher’s Paint dump site and one mile downstream. A bioassay is a living organism that serves as a detector for toxins. It is hypothesized that if the Daphnia mortality rate when exposed to water samples from various locations is higher in greater solutions, then their deaths' indicate that the water contains toxic compounds due to the harmful toxins that originated from human pollution. This is the same hypothesis for the Fletcher’s Paint experiment.

Artemia salina are used as environmental indicator species. They are used to test changes in their environment. A. salina is sensitive to toxins, temperature, and drugs. For the experiment, cysts were put into different amounts of ethanol alcohol and their viability was measured. The hypothesis used was if there is more ethanol alcohol, then the viability of the brine shrimp is unfavorable. The brine shrimp were put into sixteen Petri dishes with the same amount of brine solution. Different amounts of ethanol alcohol were added to each Petri dish. After 168 hours, the brine shrimp were

The purpose of this study is to identify four unknown organisms. The unknown organisms have been assigned randomly to six-research groups by Professor Hoffman. Each research group was provided two eukaryotes and two prokaryotes. The unknown organisms will fall into the following classifications: bacteria, algae, fungi, or protozoans. All living organisms are organized into one of three domains of life, Bacteria, Archaea, and Eukarya.
