Key facts - 1
1. The society is a dynamic and very complex chemical entity.
2. All human activity influences the chemical balance.
3. The impact may be local, regional and global, but almost always complex.
4. Significant rectifying measures are necessary and require APP.

Behind the surface
• Millions of different chemical compounds are
present;
• Numerous chemical reactions occur all the
time;
• Extremely toxic materials, with unknown
effects, are formed all the time;
• The ultimate effects of even small amounts of
anthropogenic chemicals are hard to predict.

1. The society is a dynamic and very complex chemical entity.
2. All human activity influences the natural chemical balance.
3. The impact may be local, regional and global, but almost always complex.
4. Significant rectifying measures are necessary and require APP- Awareness, Planning, Practise.

Application of APP
• Better collaboration between researchers from different disciplines;
• Base planning of research projects on the precautionary principle;
• Follow existing ethical guidelines when all research is carried out;
• Engage in outreach activities to make the public more knowledgeable and aware of the importance of chemistry in our lives.
![Page 28: Leiv K. Sydnes - UiO · Leiv K. Sydnes University of Bergen, Norway & Chair, ICSU Committee on Freedom and Responsibility in the Conduct of Science CFRS ICCE2017 Oslo, Norway; June](https://reader036.vdocument.in/reader036/viewer/2022071514/6135dbcb0ad5d2067647a52a/html5/thumbnails/28.jpg)
Some chemical knowledge among the
general public is nowadays a must
• Chemicals are and have to be everywhere!
• In consumer products - Natural ingredients - Additives – natural, synthetic • In the environment - Natural substances - Anthropogenic chemicals
![Page 29: Leiv K. Sydnes - UiO · Leiv K. Sydnes University of Bergen, Norway & Chair, ICSU Committee on Freedom and Responsibility in the Conduct of Science CFRS ICCE2017 Oslo, Norway; June](https://reader036.vdocument.in/reader036/viewer/2022071514/6135dbcb0ad5d2067647a52a/html5/thumbnails/29.jpg)
Key concepts to know something about
• Concentration of chemicals
• Solubility
• Exposure to chemicals (dose and risk)
• The form in which the chemicals are
present (speciation)
• Bioavailability
• Limitation of natural resources
![Page 30: Leiv K. Sydnes - UiO · Leiv K. Sydnes University of Bergen, Norway & Chair, ICSU Committee on Freedom and Responsibility in the Conduct of Science CFRS ICCE2017 Oslo, Norway; June](https://reader036.vdocument.in/reader036/viewer/2022071514/6135dbcb0ad5d2067647a52a/html5/thumbnails/30.jpg)
General ethical guidelines
• Ethics guiding scientific experimentation, data collection, and collaborations (Singapore statement; Montreal statement);
• Ethics guiding scientific publishing (Vancouver Convention);
• Ethics guiding scientific assessment (San Francisco Declaration):
• Ethical guidelines for outreach (ICSU Principle of Universality of Science)

Societal Considerations
Researchers as well as research institutions should recognize that they have an ethical obligation to weigh societal benefits against risks inherent in their work.

Montreal Statement on Research Integrity in Cross-Boundary Research Collaborations
1. Integrity: All partners should take responsibility for the trustworthiness of collaborative research.
2. Trust: All partners shall behave trustworthy.
3. Purpose: Collaborative research should be advance knowledge to the benefit of humankind.
7. Compliance with Laws, Policies and Regulations
9. Transparency
17. Data, Intellectual Property and Research Records

Guidelines and responsibilities for science communicators (1)
• Scientists are accountable for their public communications and should be aware of their potential impact on both science and society;
• Regardless of the audience, communications should be accurate and considered, reflecting the status of scientific evidence and uncertainty;
• Estimates of future implications and impact of scientific results should be realistic;
![Page 34: Leiv K. Sydnes - UiO · Leiv K. Sydnes University of Bergen, Norway & Chair, ICSU Committee on Freedom and Responsibility in the Conduct of Science CFRS ICCE2017 Oslo, Norway; June](https://reader036.vdocument.in/reader036/viewer/2022071514/6135dbcb0ad5d2067647a52a/html5/thumbnails/34.jpg)
• Public communication of new scientific findings should follow acceptance by peer review;
• Scientists have a special duty to communicate findings that have implications for human survival or well being, including threats to the environment;
• Scientists responding to public emergencies should be aware of the potential ramifications of their messages.

Code-of-Conduct
The challenges outlined above call for more
focus on ethical norms and standards in the
chemical community.
IUPAC has argued for and proposed
introducing a personal, living code with a
number of elements to consider.
See Graham S. Pearson, Edwin J. Becker, Leiv K. Sydnes,
Chemistry International 2011, 33 (6), 9.
![Page 36: Leiv K. Sydnes - UiO · Leiv K. Sydnes University of Bergen, Norway & Chair, ICSU Committee on Freedom and Responsibility in the Conduct of Science CFRS ICCE2017 Oslo, Norway; June](https://reader036.vdocument.in/reader036/viewer/2022071514/6135dbcb0ad5d2067647a52a/html5/thumbnails/36.jpg)
36
Draft elements for a living code
• Ensure that chemicals, equipment and
facilities under their care are not used for
illegal or harmful.
• Work in compliance with national laws and
international conventions;
• Report misuse of chemicals and facilities
to relevant authority;
• Update knowledge on risks of chemicals.
![Page 37: Leiv K. Sydnes - UiO · Leiv K. Sydnes University of Bergen, Norway & Chair, ICSU Committee on Freedom and Responsibility in the Conduct of Science CFRS ICCE2017 Oslo, Norway; June](https://reader036.vdocument.in/reader036/viewer/2022071514/6135dbcb0ad5d2067647a52a/html5/thumbnails/37.jpg)
Specific norms due to dual use
Throughout history the dual or rather multiple use of chemicals has been of utmost importance, and examples of beneficial use, misuse, or even abuse are countless.
To communicate this fact is necessary, but a challenge and a risk because without ethical standards even little knowledge in chemistry can turn into a disaster.

Fact to acknowledge
The world is chemical, and we have
to manage ourselves, our local
communities, our countries, our
regions, and the global society in
accordance with this fact.
![Page 40: Leiv K. Sydnes - UiO · Leiv K. Sydnes University of Bergen, Norway & Chair, ICSU Committee on Freedom and Responsibility in the Conduct of Science CFRS ICCE2017 Oslo, Norway; June](https://reader036.vdocument.in/reader036/viewer/2022071514/6135dbcb0ad5d2067647a52a/html5/thumbnails/40.jpg)
Science and society interplay
• The public trust in science and technology has to remain a pillar in society.
• The strength of this pillar depends critically on the collective reputation of research and researchers.
Thus:
The research community has to act in a way that is regarded as ethical by people.
