1. Investigação e avaliação da toxicidade aguda dos agrotóxicos mais utilizados no cinturão verde da Grande Natal (RN, Brasil) para o peixe-zebra (Danio rerio Hamilton Buchanan, 1822, Teleostei, Cyprinidae / Investigation and Evaluation of the acute toxicity of the agricultural chemicals most used in the green belt of Natal (RN, Brasil) on the Zebrafish (Danio rerio Hamilton Buchanan-1822, Teleostei, Cyprinidae)
The objectives of this research were to investigate the agrotoxic most used in the Gramorezinho region in the green belt of Natal, and to evaluate the acute toxicity of these, based on the LC50-48h values estimated in tests for Danio rerio, internationally used as test organism. The acute toxicity tests were performed under laboratory conditions, according t

2. Formação de aldeídos e trialometanos da desinfecção por ozonização, cloração e ozonização/cloração de efluente de tratamento anaeróbio de esgoto sanitário / Aldehydes and trihalomethanes formation from desinfection in ozonization, chloration and, ozonation/chloration in anaerobic effluent from sanitary wastewater
The present work was mostly carried out in Brazil. However, aiming to enhance the research, a six-month data collection was performed at the Wageningen University - the Netherlands. The step carried out in Brazil proposed: to study the formation of by-products (aldehydes and trihalomethanes) from the disinfection of an anaerobic treatment wastewater effluent

3. Avaliação da toxicidade de fluidos de usinagem através da ecotoxicologia aquática / Evaluation of the toxicity of fluids employed in the metallic tool industrial machining using aquatic ecotoxicology
Ecotoxicological analyses have being used to monitor environmental samples, industrial effluents and complex substances. With the objective to analyze the toxicity of cutting fluids used in the machinery industry, acute toxicity test with species of three different throphic levels: Vibrio fischeri, Daphnia similis, Daphnia laevis e Danio rerio, were performi
