Resumen
[ES] En el presente trabajo fin de máster se ha realizado una revisión bibliográfica sistemática y se han llevado a cabo dos ensayos agudos de toxicidad exponiendo a neonatos del organismo Daphnia magna a dosis crecientes de paracetamol durante 24 horas. Tras realizar la revisión bibliográfica sistemática se ha concluido que existen efectos adversos derivados de la exposición a paracetamol e ibuprofeno, tanto a niveles ambientalmente realistas como a concentraciones altas, de organismos modelo, como D. magna. Con relación a los ensayos de toxicidad aguda, se concluyó que los datos obtenidos no fueron estadísticamente significativos, por tanto, se propone como línea de investigación realizar estudios con mayor número de muestras, mayor duración y un rango más amplio de concentraciones,
[EN] In the present master's degree work a systematic bibliographic review has been carried out and two acute toxicity tests were conducted exposing Daphnia magna neonates to increasing doses of paracetamol for 24 hours. After conduct the systematic bibliographic review it has been concluded that there are adverse effects derived from exposure to paracetamol and ibuprofen, both from environmentally realistic levels and at high concentrations, in model organisms, such as D. magna. Regarding the acute toxicity test, it has been concluded that the results obtained were not statistically significant, therefore, it is proposed as a future research line to carry out studies with a greater number of samples, longer duration and with a wider range of concentrations, so that different sublethal effects can be studied and the effects (mortality) can also be observed.
