Ecotoxico-Omic and Multitrophic Assessment of the Environmental Risk Associated to Metallic Residues of Technological Products

PROYECT CODE: PID2022-133907OB-100

2024 - 2026

Electrical and Electronic Products Are Part of Our Daily Lives

Interaction with them occurs on a continuous basis.

Significant Growth Over the Past Two Decades

With an increasingly digitized society, and this trend is expected to continue upward in the years to come.

2021

The waste production reached
52 Mt

2030

The waste production estimate
74 Mt

As a result, the generation of waste from technological products, represents a global environmental problem of great concern

Many of these products contain metallic elements that are potentially toxic and can pose a health problem for ecosystems and ultimately for humans.

Specific Objectives to Contribute to Improving Ecosystem Management and Biodiversity

  • WP 1
    To design and apply different assays to evaluate the effect, individually and as mixtures, of associated metallic elements (Li, Hg, Cd, Ni, Co, Al, Mn, and rare earths (REEs)) on aquatic organisms belonging to different trophic levels.
  • WP 2
    Analyze the effect of individual elements and of their mixtures on marine, pelagic and benthic microalgae, and to understand the mechanisms involved in their toxicity and detoxification.
  • WP 3
    Analyze the impact of different elements, individually and as mixtures, on the environmental microbiome by applying different omic approaches (metagenomics and metaproteomics), in waters and sediments, and in the microbiome of the clam Scrobicularia plana, used as a relevant bioindicator organism.
  • WP 4
    Implement the application of new technologies (MALDI-Imaging) to assess the impact of the individual elements and their mixtures at the molecular level (proteomic/lipidomic) on the different tissues of the biomonitoring species Scrobicularia plana.
  • WP 5
    Examine the effect of individual elements and their mixtures on the behavioral responses, to move away and recolonize, of the crustacean Palaemon varians.
  • WP 6
    Model and prioritize the toxicity of individual elements and their mixtures considering metal speciation.
  • WP 7
    Analyze the risks associated to the toxicity of these elements and to propose a comprehensive methodology for their evaluation.
