The study aimed to evaluate the accumulation of metals in specific aquatic macrophytes to assess their potential as bioindicators or biomonitors of metal pollution. Sampling was conducted throughout the year 2021, spanning from January to December, in three distinct water bodies located in the Jaipur district of central India: Jal Mahal Lake, Amer Lake, and Nevta Lake. Both macrophyte specimens and water samples were collected from each of the three selected water bodies. The collected macrophytes were subjected to hot digestion, a common method for sample preparation in metal analysis, to extract the metals present within them. Similarly, water samples were also analyzed after appropriate preparation. The metal concentrations in both macrophyte tissues and water samples were quantified using Atomic Absorption Spectrometry (AAS-200), a widely used analytical technique known for its accuracy and sensitivity in detecting metal ions. The investigation focused on the analysis of five metals: Zinc (Zn), Lead (Pb), Nickel (Ni), Copper (Cu), and Cadmium (Cd). These metals were chosen due to their known prevalence in aquatic ecosystems and their potential toxicity to aquatic organisms, including macrophytes. Upon analysis, the accumulation levels of the selected metals in the macrophytes were determined. Based on the findings, the metals were arranged in the order of their abundance within the macrophyte tissues: Zn > Pb > Cd > Ni > Cu. This order of accumulation provides valuable insights into the relative distribution and bioavailability of metals in the aquatic environment. Such information is crucial for understanding the sources and pathways of metal pollution, as well as for assessing the potential ecological risks posed by metal contamination in aquatic ecosystems.

摘要

The study aimed to evaluate the accumulation of metals in specific aquatic macrophytes to assess their potential as bioindicators or biomonitors of metal pollution. Sampling was conducted throughout the year 2021, spanning from January to December, in three distinct water bodies located in the Jaipur district of central India: Jal Mahal Lake, Amer Lake, and Nevta Lake. Both macrophyte specimens and water samples were collected from each of the three selected water bodies. The collected macrophytes were subjected to hot digestion, a common method for sample preparation in metal analysis, to extract the metals present within them. Similarly, water samples were also analyzed after appropriate preparation. The metal concentrations in both macrophyte tissues and water samples were quantified using Atomic Absorption Spectrometry (AAS-200), a widely used analytical technique known for its accuracy and sensitivity in detecting metal ions. The investigation focused on the analysis of five metals: Zinc (Zn), Lead (Pb), Nickel (Ni), Copper (Cu), and Cadmium (Cd). These metals were chosen due to their known prevalence in aquatic ecosystems and their potential toxicity to aquatic organisms, including macrophytes. Upon analysis, the accumulation levels of the selected metals in the macrophytes were determined. Based on the findings, the metals were arranged in the order of their abundance within the macrophyte tissues: Zn > Pb > Cd > Ni > Cu. This order of accumulation provides valuable insights into the relative distribution and bioavailability of metals in the aquatic environment. Such information is crucial for understanding the sources and pathways of metal pollution, as well as for assessing the potential ecological risks posed by metal contamination in aquatic ecosystems.
