17. Toxic effects of cadmium on the microalgae Lingulodinium polyedrum using high performance liquid chromatography coupled to mass spectrometry (LC-MS/MS) / Análise dos efeitos tóxicos de cádmio sobre a microalga Lingulodinium polyedrum utilizando cromatografia líquida de alta eficiência acoplada à espectrometria de massas (LC-MS/MS)
Given the increase of environmentally harmful human activities, in particular the ones injurious to the aquatic environment, it is important to elucidate the defense mechanisms utilized by organisms exposed to damaging agents. Those species can later be suggested to be used as pollution bioindicators or bioremediatiors. Algae are of particular importance bec

19. A exposição aguda ao chumbo induz danos no DNA de vários tecidos do peixe Prochilodus lineatus
Currently there are many works describing the presence of metal pollution in water bodies. Among these metals, lead (Pb) is considered a chemical of great environmental impact due to its high toxicity to live organisms and its wide use in the industrial process of many products. Considering its toxicity and the lack of knowledge concerning lead effects to ne

20. Efeitos na saude de trabalhadores expostos a longo prazo a agrotoxicos atendidos no ambulatorio de toxicologia do Hospital de Clinicas da Unicamp nos anos de 2006 e 2007 / Effects in workers health that stayed exposed to pesticides for long time, and the ones those were attended on the Clinical Hospital of Toxicology of Unicamp during the years of 2006 and 2007
The utilization of pesticides has determined serious impacts under environmental point of view and mainly public health, with reports of contamination of several means (air, water and soil), and cases of severe intoxication and death, but with few real reports of chronic effects of exposition to these substances for long time. The goal of this study is to ev

21. Toxicidade subcrônica de lambaris Astyanax aff. bimaculatus expostos ao zinco / Subchronic toxicity in Astyanax aff. bimaculatus exposed to zinc.
Many metals occur naturally in aquatic environments and are classified as pollutants only when added by men in sufficient amounts to produce deleterious effects on organisms. Among these metals already existent on the aquatic environment it can be mentioned zinc (Zn) which is an essential element for living beings. In high concentrations, zinc can become tox

22. AnÃlise ecotoxicolÃgica do efluente da indÃstria de beneficiamento da castanha de caju antes e apÃs tratamento em reator aerÃbio inoculado com fungos / Ecotoxicological analysis of the effluent from industry to benefit from the cashew nuts before and after treatment in the aerobic reactor inoculated with fungi
The cashew nut improvement is a very important and well-developed activity in almost all states of northeast Brazil, especially CearÃ. However, there are few studies regarding the contribution of the cashew nut industry to environmental pollution in CearÃ. This industryâs wastewater contains traces of cashew nut shell liquid (CNSL), in which phenols and o

23. Análise da expressão da metalotioneína em duas espécies de peixes, Oreochromis niloticus e Prochilodus lineatus
Metallothioneins (MT) are non enzymatic proteins with with metal-binding ability. It has been used as a biomarker for environmental pollution by the analysis of its expression in several fish species. The tilapia is a commonly used model in studies of animal toxicology and some of these species have a well characterized MT sequence. Here, the Oreochromis nil
