Four New Peer-Reviewed Studies

Four New Peer-Reviewed Studies

4 published, 4 yet to come

4 published, 4 yet to come

 
 
 

Dear members and friends,

 

We are very pleased to share an important milestone in ASEQ-EHAQ’s research program: four new peer-reviewed studies on Multiple Chemical Sensitivity (MCS) have now been published in the International Journal of Environmental Research and Public Health.


Together, these publications contribute evidence across several interconnected areas: chemical exposures associated with the onset and symptom provocation of MCS; disability recognition, accommodation and socioeconomic challenges; lived experiences of fragrance-free policies;
and the existing evidence on how fragrance-free policies are defined and implemented.

 

We are also thrilled to announce that we have four more studies to come, so stay tuned for further updates as those articles become available.

 

You can read each of the open-access articles at IJERPH through the links below.

Self-Reported Chemical Exposures at Onset and Symptom Provocation in Adults with Multiple Chemical Sensitivity: A Descriptive Cross-Sectional Survey
This study examines the chemical exposures that adults with MCS reported around the onset of their condition, as well as exposures associated with subsequent symptom provocation. It contributes to a better understanding of the everyday chemical exposures reported by people living with MCS and their relationship to the experience of the condition.

When Disability Recognition Fails: Accommodation Refusals and Socioeconomic Challenges Among Canadians with Multiple Chemical Sensitivity
This study examines the experiences of Canadians with MCS when disability recognition and accommodation fail, drawing attention to the broader socioeconomic challenges associated with barriers to inclusion and accommodation.

Fragrance-Free Policies in Practice: Identifying Perceived Implementation Gaps Through Lived Experience in a Qualitative-Dominant Mixed-Methods Study
Fragrance-free policies are increasingly important tools for creating accessible environments, but having a policy does not necessarily mean that it works effectively in practice. This study examines lived experiences of fragrance-free policies and identifies perceived gaps in their implementation.
Roy, S., Diallo, N. A., Molot, J., Lattanzio, R., Bray, R., Armstrong, J., & Peris, R. (2026). International Journal of Environmental Research and Public Health, 23(8), 1077.

Fragrance-Free Policies: A Scoping Review of Definitions, Implementation, and Gaps
This scoping review examines the existing literature on fragrance-free policies, including how these policies are defined and implemented and where gaps remain. It provides an evidence base for understanding the current policy landscape and areas requiring further development.
Roy, S., Molot, J., Lattanzio, R., Armstrong, J., Bray, R., Trifunovski, A., & Peris, R. (2026). International Journal of Environmental Research and Public Health, 23(8), 1089.

Building the Evidence
While each publication addresses a different research question, together they contribute to a larger picture: understanding chemical exposures and MCS, documenting the consequences when disability and accommodation needs are not adequately recognized, and examining how fragrance-free policies can contribute to more accessible environments.


And there is more to come.

 

These four publications are part of a larger body of research currently progressing through peer review and publication. Four studies have now been published, with four more underway.


We look forward to sharing the next publications with you as they become available.


All four studies are open access and available to everyone.

 

Sincerely,
