• Abstract

  The project will assess the ecotoxicological effects of PET microplastics (¿75 µm, 330 particles·L¿¹) associated with the yellow dye tartrazine (50 mg·L¿¹, commercial grade) in adult Danio rerio through histological biomarkers. (AU)

  Ecotoxicological studies of isolated and mixed organic pollutants using histological biomarkers in Danio rerio, AP.R

• Abstract

  Microplastics (PMs) have been considered emerging pollutants, defined as any synthetic solid particle or polymeric matrix, regular or irregular in shape and with sizes ranging from 1 ¼m to 5 mm. Once introduced into freshwater environments, ecotoxicological studies that allow estimating the biological effects of microplastics are essential to understand the problem and establish acceptabl…

• Abstract

  The growing shortage of water sources ultimately demands alternatives to the treatment of pollutants. Among the many economic sectors that generate effluents, we highlight textiles with the potential to trigger ecotoxicity. Alternatives for the degradation of these effluents and pure dyes, widely used in said activity, are desirable in the environmental problem generated due to the strong…

• Abstract

  The project will evaluate the ecotoxicological effects of PET microplastic (¿75 µm, 330 particles) associated with the yellow dye tartrazine (50 mg commercial standard) in adult Danio rerio.Histological alterations in gills and liver will be analyzed, aiming to identify morphological and functional impacts resulting from co-exposure. The results will contribute to knowledge about the toxi…

  Ecotoxicological studies of isolated organic pollutants in mixtures using histological biomarkers of Danio rerio, BP.IC

• Abstract

  Aquatic contamination by microplastics is a growing concern due to their widespread dissemination, persistence and potential ecological impact. MPs are characterized by being polymers with sizes ranging from 1¿m to 5¿m and have different types, shapes and granulometries that influence their potential toxicity. It is necessary to study the toxicity of MPs isolated in different granulometri…

  "Influence of particle size on the toxicity of secondary PET microplastics isolated and in binary combinations with Chloroquine diphosphate: emphasis on histological and biochemical biomarkers of Danio rerio", BP.MS

• Abstract

  Aquatic pollution caused by microplastics (MPs) and chemical contaminants, such as heavy metals and pharmaceuticals, represents a growing environmental concern. MPs (1 µm to 5 mm) persist in the environment and can act as vectors for toxic substances, potentially enhancing or inhibiting their effects on biota. This study aims to investigate the ecotoxicological impacts of chronic exposure…

  Ecotoxicological aspects of polyethylene terephthalate fragments isolated and mixed with a metal pollutant and a pharmaceutical: emphasis on histological biomarkers of Danio rerio, BP.IC

• Abstract

  Pollution of aquatic environments by inorganic and organic chemicals is one of the main factors that is shown to be a serious threat to the survival of the biota present in said system. Due to the growth of industrial production in the last decades the manufacture and use of synthetic chemical compounds has been intensively increased. In this context, we highlight the textile and food ind…

  Ecotoxicological aspects of Tartrazine dye on the Danio rerio species before and after the use of different classes of treatments, BP.IC

• Abstract

  The reservoir Itupararanga is inserted into an area of around multiple uses, especially human activities related to agricultural cultivation, urban expansion areas and areas of environmental protection. Among the waste generated by the occupations described above, we highlight the possible pesticides used to combat pests of crops, fertilizers and sewage dumps. Through the sources of point…

  Limnological and ecotoxicological aspects of water samples from the reservoir Itupararanga (Ibiuna-SP): emphasis on cyanotoxins potential, BP.IC

• Abstract

  Chemicals with potential to deregulate the endocrine systems of vertebrates and invertebrates have been detected in aquatic environments worldwide in concentrations on the order of ppb (part per billion). Among them we highlight the natural and artificial hormones, present in wastewater that are discharged into the environment without treatment or water treatment ineffective for their rem…
