Quantitative analyses of results of the sea urchin toxicity tests based on

Maria Valéria Souza Barbosa, João Inácio Silva Filho, Augusto Cesar


The toxicity tests are an important tool to control and environmental monitoring and its results provide direct evidence of the effects of marine pollution. The sea urchin has been widely used in toxicity tests to assess and characterize a variety of samples, whether municipal or industrial effluents, such as chemicals and environmental samples. Usually, the readings of the data relating to the results of toxicity tests require experience and technical acumen of responsible, therefore, can infer certain subjectivity, the fact that in many cases, generate conflicting results. This work aims to investigate new forms of treatment of data resulting from such toxicity tests using algorithms based on non-classical logics. Based on the data collected are used algorithms Annotated Paraconsistent Logic, aiming to find monitoring procedures that can add to the reliability analysis through computer programs.
