The report is based on a study of the scientific literature on Multiple Chemical Sensitivity, MCS, in Denmark called odour and chemical hypersensitivity.

MCS differs from the common scientific understanding of illness because the condition is always manifested by multiple non-specific symptoms from different organs at the same time and because these symptoms may occur after exposure to chemicals at very low concentrations.Læs publikation
