Emerging contaminants in the environment: Risk-based analysis for better management

Area of Science:

• Environmental Science
• Toxicology
• Ecotoxicology

Background:

• Emerging contaminants (ECs) are chemicals with recently discovered origins and unestablished risks.
• ECs include pharmaceuticals, pesticides, nanomaterials, and personal care products, posing a global environmental challenge.
• Limited data exists on ECs' interactions, toxicological impacts, and environmental fate and transport.

Purpose of the Study:

• To provide an overview of current knowledge on emerging contaminants.
• To analyze the fate and transport of ECs in the environment.
• To present a risk-based analysis for EC management strategies.

Main Methods:

• Literature review of existing knowledge on ECs.
• Analysis of ECs' environmental fate and transport mechanisms.
• Risk-based assessment for EC management.

Main Results:

• ECs are widespread globally, with diverse sources and types.
• Significant knowledge gaps exist regarding ECs' environmental behavior and toxicological effects.
• Current analytical techniques and resources are insufficient for comprehensive EC assessment.

Conclusions:

• ECs represent a significant and growing global environmental and public health concern.
• Further research is crucial to understand ECs' interactions, impacts, and develop effective management strategies.
• A risk-based approach and complementary strategies are needed for ECs management.
