INTRODUCTION AND AIM
In the textile industry, great quantities of water containing dyes are released into the aquatic ecosystem and can pose risks to humans and biota Research on natural resources has increased and biocolourants have been investigated as an alternative source of colour for textiles to synthetic dyes. In this work, we used two highly purified anthraquinone dyes 98 selected by BioColour project, dermorubin and dermocybin extracted from the fungus Cortinarius sanguineus and evaluated their aquatic toxicity.
MATERIAL AND METHODS
-
Acute toxicity was evaluated with freshwater microcrustacean Daphnia similis the marine crustacean, Parhyale hawaiensis and the freshwater fish Danio rerio in an embryotoxicity (FET) test .
-
Chronic toxicity tests were evaluated with the green microalgae Raphidocelis subcapitata and the freshwater crustacean Ceriodaphnia dubia.
RESULTS
-
Mutagenicity assay (Ames test) were previously performed and provided negative results for both dyes;
-
Dermorubin was not toxic to any of the organisms;
-
Dermocybin was toxic to D similis C dubia and zebrafish embryos.
