1. Diagnóstico ecotoxicológico dos efluentes lançados no complexo estuarino do Jundiaí/Potengi, Natal/RN
Untreated effluents that reach surface water affect the aquatic life and humans. This study aimed to evaluate the wastewaters toxicity (municipal, industrial and shrimp pond effluents) released in the Estuarine Complex of Jundiaí- Potengi, Natal/RN, through chronic quantitative e qualitative toxicity tests using the test organism Mysidopsis Juniae, CRUSTACE

2. Study of electrochemical degradation, photochemical, and photocatalytic eletrofotocatalitica the hormone ethinylestradiol / Estudo da degradação eletroquímica, fotolítica, fotocatalítica e eletrofotocatalítica do hormônio etinilestradiol
In recent years, the environmental research has been facing serious problems in relation to some substances in the aquatic environment in small concentrations, such as the endocrine desruptores pharmaceuticals, natural and synthetic hormones, pesticides, tensosativas substances, polymers of low molar mass and different other organic contaminants present in m

3. Uso urbano não potável de efluentes de estações de tratamento de esgoto sanitário : estudo de caso : município de Campo Largo - PR
The use of effluents in situations where lower quality waters is accepted, in addition to mitigate the hidric pollution, it also provides this same quantity to the potable supply, increasing the offer and creates the optimisation of the hydric resources. Believing in a sustainable development as a goal to reach, this work describes the possibilities of utili

4. Estudo de modificadores quimicos e superficies modificadas para a determinação de estanho por espectrometria de absorção atomica com forno de grafite
Tin is an important element from an environmental viewpoint and is essential for humans at trace levels. However, the direct determination of tin by graphite furnace AAS has been fraught with problems such as volatilization loss, interaction with the graphite surface and sample matrix interference. In the present work, the use of the calcium, barium and stro

5. Nitrification in the intertidal zone: influence of effluent type and effect of tannin on nitrifiers.
Nitrification by intertidal sediments was measured by using a tide simulator that approximated the cycle of seawater on tidal flats. Sediments were chosen from sites affected by industrial and municipal effluents and pastoral seepage and runoff. The ability of sediments from different sites to nitrify endogenous nitrogen varied markedly. All sites exhibited
