phytoremediation with salvinia minima (salvineaceae): identification of temporal biomarkers during cr(vi) removal |
| description |
Background and aims: Heavy metals pollution, particularly by hexavalent chromium, is a topic of global concern due to its high toxicity and environmental persistence. Phytoremediation emerges as a nature-based economic technology for the recovery of environments contaminated by metals. In the case of water bodies, aquatic macrophytes such as Salvinia minima Baker are excellent candidates as remedial species. To optimize its use, it is important the identification of efficient and reliable biomarkers. The objective of this work was to carry out a temporal analysis of different biochemical parameters to identify both biomarkers of exposure to Cr(VI) and the most appropriate time for their analysis in S. minima plants under laboratory conditions.
M&M: Specimens of S. minima were cultured in the presence or absence of hexavalent chromium for seven days under controlled light and temperature conditions. Tissue and culture solution samples were taken at 0, 2, 4 and 7 days. The levels of H2O2, malondialdehyde, soluble and insoluble phenols and sucrose were quantified in floating pinnae and submerged rachis. Remaining Cr(VI) was determined in the treatment solution. All determinations were performed spectrophotometrically.
Results: The results allowed us to identify, among the selected parameters, early (malondialdehyde), medium-term (sucrose and insoluble phenols) and late (hydrogen peroxide) biomarkers.
Conclusions: The physiological implications of the observed variations are analyzed and discussed. |

Introducción y objetivo: La contaminación por metales pesados, y en particular por cromo hexavalente, es un tema de preocupación mundial debido a la alta toxicidad y persistencia ambiental que exhibe este metal. La fitorremediación surge como una tecnología económica para la recuperación de ambientes contaminados por metales. Las macrófitas acuáticas, como Salvinia mínima, son excelentes candidatas como especies remediadoras de cuerpos de agua. Para optimizar su utilización es importante la identificación de biomarcadores eficientes y confiables. El objetivo del presente trabajo fue realizar un análisis temporal de distintos parámetros bioquímicos para identificar tanto biomarcadores a la exposición a Cr(VI) como el momento más apropiado para su análisis en plantas de S. minima bajo condiciones de laboratorio. M&M: Se cultivaron ejemplares de S. mínima en presencia y ausencia de cromo hexavalente, durante siete días, en condiciones controladas de luz y temperatura. Se tomaron muestras de tejidos y de la solución de cultivo a los 0, 2, 4 y 7 días. Se cuantificaron los niveles de H2O2, malondialdehído, fenoles solubles e insolubles y sacarosa, en pinnas flotantes y raquis sumergido. En la solución de tratamiento se determinó Cr(VI) remanente. Todas las determinaciones se realizaron espectrofotométricamente. Resultados: Los resultados permitieron identificar, entre los parámetros seleccionados, biomarcadores tempranos (malondialdehído), de mediano plazo (sacarosa y fenoles insolubles) y tardíos (peróxido de hidrógeno). Conclusiones: Se analizan y discuten las implicancias fisiológicas de las variaciones observadas.
