1. Multiresidue Determination of Endocrine Disrupting Compounds in Sewage Treatment Plants (SPE-HPLC-DAD)
This work focuses on the validation and application of solid phase extraction followed by high-performance liquid chromatography (SPE-HPLC) analysis of important endocrine disruptors compounds (EDC) from different classes in highly complex wastewater matrix. The endocrine disruptors investigated included three different categories: pharmaceuticals (sulfameth

2. A case of intersex occurrence in Steindachneridion parahybae (Steindachner, 1877) (Siluriformes: Pimelodidae) under captivity condition: a cytogenetic and morphological study
ABSTRACT Little is known about reproductive biology of endangered Steindachneridion parahybae , a gonochoristic teleost species inhabiting the Paraíba do Sul River Basin, and herein is the first description of intersex in S. parahybae juvenile. The normal appearance of ovaries and testes in juvenile from the same lot of breeding were also described for comp

3. Screening of By-Products of Esfenvalerate in Aqueous Medium Using SBSE Probe Desorption GC-IT-MS Technique
The pyrethroids, their metabolites and by-products have been recognized as toxic to environment and human health. Despite several studies about esfenvalerate toxicity and its detection in water and sediments, information about its degradation products is still scanty. In this work, esfenvalerate degradation products were obtained by chemical oxidation with h

4. Quantitative Analysis of Endocrine Disruptors by Comprehensive Two-Dimensional Gas Chromatography
Comprehensive two-dimensional gas chromatography has been successfully applied to the analysis of various organic contaminants; however, few studies report its use in the analysis of endocrine disrupting compounds. These compounds are suspected to cause dysfunction of the endocrine system in humans and animals. This work describes the development of a method

5. Vortex-assisted hollow-fiber liquid-phase microextraction coupled with high performance liquid chromatography for the determination of three synthetic endocrine disrupting compounds in milk
Neste estudo, uma microextração em fase líquida suportada em fibra oca e com agitação vórtex (VA-HF-LPME) acoplada à cromatografia líquida de alta performance (HPLC) foi desenvolvida para a determinação de três compostos endócrinos sintéticos desreguladores [EDCs, bisfenol-A (BPA), bisfenol-AF (BPAF) e tetrabromobisfenol-A (TBBPA)] em amostras d

6. DeterminaÃÃo de Micropoluentes Emergentes em Esgoto SanitÃrio, Hospitalar e Ãguas Superficiais / Determination of Emerging Micropollutants in Sewage, and Surface Water Hospital
No Brasil, estudos de avaliaÃÃo de micropoluentes emergentes em matrizes ambientais como esgotos sanitÃrios e hospitalares, e corpos de Ãgua, ainda sÃo bastante incipientes, assim como a remoÃÃo desses compostos em EstaÃÃes de Tratamento de Esgotos (ETEs) de baixo custo como lagoas de estabilizaÃÃo, assim como em sistemas de lodos ativados e siste

7. Triorganotin as a compound with potential reproductive toxicity in mammals
Organotin compounds are typical environmental contaminants and suspected endocrine-disrupting substances, which cause irreversible sexual abnormality in female mollusks, called "imposex". However, little is known about the capability of triorganotin compounds, such as tributyltin and triphenyltin, to cause disorders in the sexual development and reproductive

8. Remoção de desreguladores endócrinos por fotocatálise heterogênea e ozonização / Removal of endocrine disrupting compounds by photocatalysis and ozonation
Desreguladores endócrinos são compostos que podem alterar o sistema endócrino dos indivíduos, bem como sua fertilidade e por em risco a saúde dos mesmos. Muitas questões relacionadas a esses compostos ainda não foram elucidadas, apesar de serem muito estudados recentemente. Diversas pesquisas têm sido feitas investigando-se o emprego de processos oxi

9. Interferentes endócrinos no ambiente
Although the hypothesis that environmental chemicals may exhibit endocrine disrupting effects is not new, the issue has been a growing level of concern due to reports of increased incidences of endocrine-related disease in humans, including declining male fertility, and more significantly, to adverse physiological effects observed in wildlife where cause and

10. Degradation of dioxinas and furanos policlorados for ligninolíticos basidiomecetos fungos and its application in biorremediação process. / Degradação de dioxinas e furanos policlorados por fungos basidiomicetos ligninoliticos e sua aplicação em processo de biorremediação.
Polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) are compounds produced as by-products, unintentionally, in industrials processes and combustion processes. Municipal solid waste incineration is one major source these compounds. The isomers with chlorines substituted in the 2,3,7,8 positions are thought to cause risks to human hea

11. THE IMPORTANCE AND OCCURRENCE OF PHTHALATES IN POTABLE WATERS AND SAMPLES FROM THE GUANABARA BAY ECOSYSTEM / A IMPORTÂNCIA E OCORRÊNCIA DE FTALATOS EM ÁGUA POTÁVEL E NO ECOSSISTEMA DA BAÍA DE GUANABARA
Phthalates are the most used plasticizers in industrial products, worldwide distributed in environments. Their presence is often used to indicate a region industrialization degree. Although their reported toxicity is low, phthalates are indicated for possible endocrine disrupting effects, specially in male reproductive system. In Brazil, there are few studie

12. Eggshell and egg yolk proteins in fish: hepatic proteins for the next generation: oogenetic, population, and evolutionary implications of endocrine disruption
The oocyte is the starting point for a new generation. Most of the machinery for DNA and protein synthesis needed for the developing embryo is made autonomously by the fertilized oocyte. However, in fish and in many other oviparous vertebrates, the major constituents of the egg, i.e. yolk and eggshell proteins, are synthesized in the liver and transported to
