Ecological risk assessment of Piper aduncum essential oil in non-target organisms

Uma possivel alternativa ao uso de farmacos veterinarios no tratamento e prevencao de doencas na piscicultura e o uso do oleo essencial de Piper aduncum. No entanto, sao necessarios dados ecotoxicologicos para garantir seu uso apropriado sem causar efeitos adversos a organismos nao alvo. Esta informacao e relevante, pois esse oleo essencial e descrito como tendo atividades inseticidas, moluscicidas e citotoxicas, possivelmente associadas a sua composicao quimica. Assim, o objetivo deste estudo foi avaliar a ecotoxicidade do oleo essencial de P. aduncum para cinco organismos-teste, usando o metodo estatistico da Distribuicao da Sensibilidade das Especies (SSD). One possible alternative to chemotherapeutic agents in the treatment and prevention of diseases in fish farms is the use of Piper aduncum essential oil. However, ecotoxicological data are required to ensure its proper use and to prevent adverse effects on non-target organisms. These data are relevant since this essential oil is described as having insecticidal, molluscicidal and cytotoxic activitiy that may be associated with its chemical composition. Thus, the aim of this study was to evaluate the ecotoxicity of P. aduncum essential oil to five test organisms using the species sensitivity distribution (SSD) statistical approach.
