Chemical sensitivity, asthma, and effects from fragranced consumer products: National Population Study in the United Kingdom

Abstract

Consumer products, such as those with a fragrance, can adversely affect air quality and health. This national study in the United Kingdom (UK) investigated the prevalence of chemical sensitivity, a condition associated with chemical pollutant exposures, and the medical diagnosis of multiple chemical sensitivities (MCS).
