DOI Assignment and Versioning Policy

All scholarly content published within the “Pollution and Diseases” publishing ecosystem is assigned a Digital Object Identifier (DOI) through Crossref under the prefix:

10.66659

This DOI policy ensures consistency, transparency, and long-term persistence of identifiers across all publication platforms, including the journal, repository, book publications, and conference outputs.

DOI Assignment Policy

The journal currently uses an automatic DOI registration system.
DOIs are assigned automatically during the publication process through the integrated journal management platform.

The differentiation between journal issues, repository materials, and conference proceedings is now managed through separate journal volumes and issues rather than through different DOI assignment schemes.

Each published article receives a unique DOI automatically after being scheduled and published within the corresponding issue or volume.

This system ensures:

• automatic DOI generation;
• consistent metadata registration;
• simplified publication workflow;
• clear separation of journal articles, repository publications, and conference materials by issue structure.

Authors and editors are no longer required to manually request or configure DOI identifiers.

Rights and Licensing

Journal articles are published under Creative Commons licensing (CC BY 4.0).

Book Series volumes are commercial publications and are distributed under “All rights reserved” unless otherwise specified.

Repository items indicate licensing conditions individually.

Each DOI record clearly displays its rights status.
