Resumo
O Irgarol 1051 é um dos biocidas presentes nas tintas de anti-incrustantes de terceira geração e pode ter o seu destino final os sistemas aquáticos como os rios, estuários e mares. A ERA (Ecological Risk Assessment) caracteriza o risco ambiental proveniente de uma substância a partir de ensaios ecotoxicológicos. No entanto, os ensaios mais utilizados são os de nível de organização individual que podem não expressar a concentração segura para os organismos aquáticos. Em contrapartida, os níveis mais baixos, como o subindividual que pode avaliar biomarcadores, podem não ser suficientes para prever danos nos níveis mais altos como comunidade. Portanto, a revisão sistemática se faz necessária para compreender a sensibilidade dos organismos-teste e níveis de organização biológica sob efeito do biocida Irgarol e gerar subsídios para as políticas públicas de enfrentamento do problema ambiental dos biocidas anti-incrustantes. O objetivo deste estudo é compreender quais são as concentrações de efeito do Irgarol para diferentes organismos-teste, os quais se enquadram em diferentes níveis de organização biológica e avaliar (i) frequência de utilização e (ii) sensibilidade de organismos-teste e níveis de organização biológica. A hipótese do presente estudo era de que a sensibilidade dos organismos-teste de diferentes níveis de organização biológicas apresentassem um gradiente de sensibilidade, no qual as menores concentrações de efeito estão situadas nos menores níveis (p.ex.: bioquímico) seguindo para os maiores níveis de organização biológica (p. ex.: população e comunidade) com as maiores concentrações de efeito. O estudo consistiu em compilar os dados provenientes de artigos científicos sobre os efeitos do Irgarol em diferentes níveis de organização biológica conduzidos em matriz de água doce/estuarina/marinha. Com o auxílio de um computador com acesso à internet, os dados foram pesquisados com palavras-chave pré-definidas e suas combinações nas plataformas Web of Science, Pan Pesticide Database, Pubmed, Scopus e USEPA Ecotox Database e sintetizados em uma tabela de acordo com componentes abióticos e bióticos e posteriormente dividido de acordo com a matriz. O organismo-teste alga e a matriz marinha foram os mais utilizados para avaliar os efeitos do biocida Irgarol. As algas apresentaram concentrações de Irgarol similares para subindividual/fisiologia e população/taxa de crescimento na matriz de água marinha e há dados insuficientes para as outras matrizes.
Irgarol 1051 is one of the biocides present in third generation antifouling paints and may have its final destination in aquatic systems such as rivers, estuaries and seas. ERA (Ecological Risk Assessment) characterizes the environmental risk from a substance based on ecotoxicological tests. However, the most used tests are those of individual organization level that may not express the safe concentration for aquatic organisms. In contrast, the lower levels, such as the subindividual that can assess biomarkers, may not be sufficient to predict damage at the highest levels as a community. Therefore, a systematic review is necessary to understand the sensitivity of the test organisms and levels of biological organization under the effect of the biocide Irgarol and to generate subsidies for public policies to face the environmental problem of anti-fouling biocides. The objective of this study is to understand what are the Irgarol effect concentrations for different test organisms, which fall under different levels of biological organization and to evaluate (i) frequency of use and (ii) sensitivity of test organisms and levels of biological organization. The hypothesis of the present study was that the sensitivity of test organisms of different levels of biological organization had a sensitivity gradient, in which the lowest concentrations of effect are located at the lowest levels (eg biochemical), moving towards the highest levels of biological organization (eg population and community) with the highest concentrations of effect. The study consisted of compiling data from scientific articles on the effects of Irgarol at different levels of biological organization conducted in a freshwater / estuarine / marine matrix. With the aid of a computer with internet access, the data were searched using predefined keywords and their combinations on the Web of Science, Pan Pesticide Database, Pubmed, Scopus and USEPA Ecotox Database platforms and synthesized in a table according to abiotic and biotic components and later divided according to the matrix. The test organism alga and the marine matrix were the most used to evaluate the effects of the biocide Irgarol. The algae showed similar concentrations of Irgarol for subindividual / physiology and population / growth rate in the marine water matrix and there are insufficient data for the other matrices.
