As scientific understanding of toxicology and environmental science evolves, emission limits are likely to become more stringent. The development of new technologies and methods for detecting and assessing pollutants will enhance the ability to set more accurate and protective standards. Additionally, global cooperation and harmonization of regulations will be essential to address transboundary pollution issues and ensure a sustainable future.
In conclusion, emission limits are a vital component of environmental and public health protection. They are informed by toxicological research and are enforced through a combination of regulatory oversight and technological innovation. As the world continues to grapple with the challenges of pollution and climate change, the role of emission limits in safeguarding health and the environment will remain indispensable.
