Chemical Indoor Air Pollution Now Considered as Harmful as Tobacco Smoke

The World Health Organization now ranks air pollution among the top five major risk factors for chronic, non-communicable diseases, such as cardiovascular, respiratory, and neurodegenerative disorders, alongside tobacco use, harmful alcohol consumption, unhealthy diets, and physical inactivity.

Given that most people spend 90% of their time indoors, where the concentration of chemical pollutants can be higher than outdoors, the impact of indoor air quality on health is significant.

What is Multiple Chemical Sensitivity

Multiple Chemical Sensitivity (MCS) is a condition where low-dose exposures to various substances, which are often tolerated by the general population, cause adverse reactions.

These reactions occur on a cellular level, where receptors designed to detect foreign substances are stimulated, leading to a cellular response for detoxification.

However, a recent report by the National Institute of Public Health Qu├ębec (INSPQ) controversially concluded that MCS is caused by anxiety, overlooking a substantial body of scientific evidence indicating that MCS is a biological condition due to receptor sensitization to chemicals.

This report has been criticized for its methodology and for ignoring the role of these receptors in MCS.

The refusal to acknowledge the significance of omitted peer-reviewed literature or to engage in transparent scientific discussions undermines the credibility of the report.

The INSPQ’s approach also neglects established research protocols that emphasize the importance of patient partnership in research. The exclusion of patient and expert input, despite assurances of inclusion, further biases their conclusions.

Meanwhile, individuals with severe MCS, struggling to find suitable housing, are left with dire options, including medically assisted death. This extreme measure highlights the urgency of addressing MCS with proper understanding and support.

The denialism evident in the INSPQ report, similar to tactics used by the tobacco and oil industries, selectively accepts evidence that supports pre-existing beliefs while disregarding new research.

This approach not only misrepresents the science but also potentially harms the over one million Canadians diagnosed with MCS.

The Key Takeaway

It is essential for those in positions of authority, who maintain influential opinions based on flawed research, to acknowledge and correct their errors. The scientific community must prioritize evidence-based conclusions over biased opinions to provide the necessary support and understanding to individuals suffering from MCS.
