Resources and Support for Multiple Chemical Sensitivities, Environmental Illness, and Chemical Injuries in Canada


Sincere thanks and gratitude go to Brenda, from MCS-CanadianSources, who originally compiled this list of MCS-specific research. The list is far from complete in terms of ongoing MCS research, but will be updated as regularly as possible.

Case-control study of genotypes in multiple chemical sensitivity: CYP2D6, NAT1, NAT2, PON1, PON2, and MTHFR.  Canadian content site  McKeown-Eyssen, G, C Baines, DEC Cole, N Riley, RF Tyndale, L Marshall, V Jazmaji. 2004. "This groundbreaking study by McKeown-Eyssen et al. is the first to show genetic differences in enzymes important to detoxification of contaminants comparing people with MCS to those who don¬ít have the condition. It thus provides significant genetic evidence for the existence of MCS as a physically-based phenomenon, not something existing 'only in the mind of the patient,' as skeptics of the condition have asserted."

A cross-section study of self-reported chemical-related sensitivity is associated with gene variants of drug-metabolizing enzymes

Symptom Profile of Multiple Chemical Sensitivity in Actual Life Saito M, Kumano H, Yoshiuchi K, Kokubo N, Ohashi K, Yamamoto Y, Shinohara N, Yanagisawa Y, Sakabe K, Miyata M, Ishikawa S, Kuboki T. 2005. "Objective: This study was conducted to confirm the definition of multiple chemical sensitivity (MCS) in actual life: that multiple symptoms are provoked in multiple organs by exposure to, and ameliorated by avoidance of, multiple chemicals at low levels. We used the Ecological Momentary Assessment to monitor everyday symptoms and the active sampling and passive sampling methods to measure environmental chemical exposure ... Conclusions: MCS patients do not have either somatic or psychologic symptoms under chemical-free conditions, and symptoms may be provoked only when exposed to chemicals."
