Summary
This study reviews the history and current state of hygienic standards, comparing methods used in the USA and USSR. It highlights international efforts to standardize Maximum Allowable Concentrations (MAC) and carcinogen classifications.
Area of Science:
- Environmental Health Sciences
- Occupational Health
- Toxicology
Background:
- Hygienic standards setting is crucial for public and occupational health.
- Historical approaches to setting exposure limits have varied significantly across nations.
- International collaboration aims to harmonize these standards.
Purpose of the Study:
- To present the historical evolution and current status of hygienic standards setting globally.
- To compare methodological approaches to setting exposure limits in the USA and the former USSR.
- To examine the role of international organizations in standardizing definitions and approaches to Maximum Allowable Concentrations (MAC).
Main Methods:
- Comparative analysis of hygienic standards setting methodologies in the USA and USSR.
- Review of contributions by international organizations to MAC setting.
- Examination of MAC setting systems in the USA (ACGIH, NIOSH, OSHA), former USSR, Germany, Scandinavian countries, Hungary, and Poland.
- Analysis of substance and carcinogen classifications by the International Agency for Research on Cancer (IARC) and national bodies.
Main Results:
- Significant differences and similarities were identified in the historical and current approaches to hygienic standards setting between the USA and the former USSR.
- International organizations have played a key role in promoting a unified definition and approach to MAC setting.
- Various countries employ distinct systems for setting MACs and classifying carcinogens, with IARC classifications serving as a global reference.
Conclusions:
- Understanding diverse national approaches to hygienic standards is essential for effective risk management.
- Continued international cooperation is vital for advancing global occupational and environmental health protection.
- Harmonization of MAC setting and carcinogen classification remains an ongoing process with significant implications for public health policy.
