Curated mode-of-action data and effect concentrations for chemicals relevant for the aquatic environment

Area of Science:

• Environmental Toxicology
• Ecotoxicology
• Chemical Risk Assessment

Background:

• Aquatic ecosystems face threats from harmful environmental chemicals.
• Understanding chemical effects and interactions is crucial for accurate risk assessment.
• Identifying toxic compounds requires knowledge of their biological mechanisms.

Purpose of the Study:

• To develop a pipeline for extracting and summarizing ecotoxicity data.
• To compile a comprehensive collection of chemical modes of action.
• To create a curated dataset for environmental chemical risk assessment.

Main Methods:

• Harvesting and summarizing effect concentrations from the US ECOTOX database for algae, crustaceans, and fish.
• Researching modes of action for over 3,300 environmentally relevant chemicals using literature and databases.
• Developing criteria for data curation and categorization.

Main Results:

• A curated dataset of effect concentrations for key aquatic species.
• The first comprehensive collection and categorization of modes of action for environmental chemicals.
• A robust pipeline for data acquisition and summarization.

Conclusions:

• The developed dataset and categorized modes of action are valuable for chemical risk assessment.
• This resource supports chemical grouping and the development of alternative testing strategies (in vitro, in silico).
• Authorities, regulators, and scientists can utilize this data for improved environmental protection.
