    In this short course, we cover topics pertaining to the molecular and toxicological properties of organic dyes.  Emphasis is placed on the structures and chemical and physical properties of dyes for each type of textile fiber (cotton, polyester, nylon, etc.).  The opening lecture covers the bases for the color of dyes and their coloration of textile fibers and the chemical and physical mechanisms associated with textile dyeing.  This is followed by a series of lectures providing an overview of the technical properties of the important classes of textile dyes, along with factors governing the selection of individual colorants for specific end uses.  The final group of lectures provide up to date perspectives on eco/genotoxicology and analytical chemistry of synthetic dyes.

  2. The use of zebrafish embryos in ecotoxicology
    Date: 15th July 2017
    Period: 08h-18h (8 hours)
    Number of participants: 50
    Registration fee: R$ 80,00 per participant.

    Worldwide, academy, research centres, industries and governmental agencies are performing fish embryos assays to evaluate the ecotoxicity of isolated chemicals or complex mixtures, such as environmental samples. Featuring a number of advantages, zebrafish embryos are gaining space with new standardized international protocols [1]. Noteworthy are also numerous advanced methodologies that allow the use of various types of experimental approaches ranging from phenotypic observations, functional gene tests, among others. Furthermore, in accordance with international standards of animal welfare, fish embryos provide a test system on a small scale, ethically acceptable to the complexity needed to replace an adult organism altogether. The short course “The use of zebrafish embryos in ecotoxicology” was held for the first time in 2012 during the XII Brazilian Congress of Ecotoxicology (ECOTOX 2012) with a second and a third editions during the ECOTOX 2014 and 2016, respectively. The main aim of the course is to promote zebrafish embryos as a potential alternative to ecotoxicological assays using adult animals [2]. For the 17th International Symposium on Toxicity Assessment (ISTA17) the course will focus on: the use of fish in ecotoxicology; ethical issues related to the use of animals and fish embryos in science; zebrafish maintenance, reproduction and nutrition; standardized protocols of Fish Embryo Test (FET); case-studies and applications of FET.
