Paperwork Research Plan Effects of Marine Engine Exhaust Water on Algae By Science E Genius This project in its present form is the result of bioas-say experimentation on the effects of two-cycle ma-rine engine exhaust water on certain green algae The initial idea was to determine the toxicity of out-board engine lubricant Some success with lubricants eventually led to the formulation of ldquosyntheticrdquo ex-haust water which in turn led to the use of actual two-cycle engine exhaust water as the test sub-stance Toxicity was determined by means of the standard bottle or ldquobatchrdquo bioassay technique Scenedesmus quadricauda and Ankistrodesmus sp were used as the test organisms Toxicity was measured in terms of a decrease in the maximum standing crop The effective concentration - 50 (EC50) for Scenedes-mus quadricauda was found to be 375 exhaust water for Ankistrodesmus sp 31 exhaust water using the bottle technique Anomalies in growth curves raised the suspicion that evaporation was affecting the results therefore a flow-through system was improvised utilizing the characteristics of a device called a Biomonitor Use of a Biomonitor lessened the infl uence of evapora-tion and the EC 50 was found to be 14 exhaust water using Ankistrodesmus sp As the test organ-ism Mixed populations of various algae gave an EC 50 of 128 exhaust water The contributions of this project are twofold First the toxicity of two-cycle marine engine exhaust was found to be considerably greater than reported in the literature (14 vs 42) Secondly the benefits of a flow-through were shown
All projects require the following forms to compete in the Duplin Coun-ty Schools Science Fair Form 1 (Checklist for Adult Spon-
sor) Form 1A (Student Checklist) Form 1B (Approval Form) Research Plan Abstract Elementary and Middle School pro-jects also require the NCSEF Re-search Plan Approval Form
