Advances, Norms, and Perspectives in Product Chemical Footprint Research

Area of Science:

• Environmental Science
• Chemical Engineering
• Risk Assessment

Background:

• Chemical footprints are crucial for assessing human toxicity and ecotoxic effects of pollutants.
• Evaluating chemical risks throughout a product's lifecycle is essential for environmental management.

Purpose of the Study:

• To review and unify research on chemical and product chemical footprints.
• To propose standardized methods for calculating product chemical footprints.
• To provide a normative reference for enterprises and research institutions.

Main Methods:

• Literature review of chemical footprint research progress.
• Identification and unification of key issues in footprint calculation (e.g., accounting boundaries, data, methods, evaluation).
• Development of proposed methods for product chemical footprint evaluation.

Main Results:

• A comprehensive review of the current state of chemical footprint research.
• Standardized approaches to key calculation elements: accounting boundaries, data lists, methods, and result evaluation.
• Proposed methodologies for evaluating product chemical footprints.

Conclusions:

• Standardized product chemical footprint evaluation is vital for chemical risk identification, assessment, and control.
• Future research should focus on chemical footprint labels, characterization factors, databases, and environmental management mechanisms.
