Transcriptomic resources for environmental risk assessment: a case study in the Venice lagoon

Area of Science:

• Environmental Science
• Marine Biology
• Ecotoxicology

Background:

• Evaluating environmental status is crucial for ocean and coastal management.
• Eco-toxicogenomics integration in marine health assessments is a growing initiative.
• Technical challenges hinder the regulatory use of genomics in ecotoxicology.

Purpose of the Study:

• To investigate the role of genomics in environmental monitoring.
• To identify reliable gene expression markers for chemical contamination.
• To assess environmental risks in the Venice lagoon from industrial activities.

Main Methods:

• Utilized transcriptomics to define gene expression markers.
• Focused on Manila clams as bioindicators.
• Applied markers to classify areas within the Venice lagoon based on contamination.

Main Results:

• Successfully defined gene expression markers associated with chemical contamination.
• Demonstrated the potential of these markers for classifying environmental areas.
• Provided insights into the application of genomics for risk assessment.

Conclusions:

• Genomics holds significant potential for future environmental monitoring.
• Reliable gene expression markers can aid in assessing marine ecosystem health.
• Further development is needed to integrate genomics into regulatory ecotoxicology.
