Aims and Tasks

Aims

  1. To identify the most likely ECs occurring in the water column of the selected estuarine and coastal zones . 
  2. To estimate the exposure of target organisms  to ECs  and to assess the most likely effects .
  3. To estimate the fraction of the most likely emerging contaminant that is available in the food chain and to end consumers (bioaccesibility and bioavailability) .

Aims

Tasks

disruptive chemicals

  • To carry out non-target analysis in coastal water and biota samples to identify hot-spots and priorize ECs.
  • To validate target methods in water and biota and to monitor EC levels in mussels.
  • To calibrate the  different passive samplers (according to the polarity of the target contaminants) and apply in the hot-spots.
  • To estimate the body burden of ECs and transformation products in fishes and mussels.
  • To assess exposure biomarkers to diagnose the type of effect (endocrine disruption, intersex, ....).
  • To build the metabolomic profiles in lab exposed organisms to distinguish exposure levels and eventually to identify some mechanisms of toxicity.
  • To develop PBET assays through the development of validated batchwise oral bioaccessibility and miniaturized dynamic flow-through methods in seafood and fish
  • To automatize  the gastrointestinal extraction process.
  • To develop 3D dispersion models of ECs in Galician Rias for backtracking the contaminants detected in the molluscs and fishes to potential contamination sources
