A study of 132 unoccupied and 60 occupied caravans was conducted to determine levels of formaldehyde and factors which may affect these levels. Repeat monitoring was carried out 6 months later in 50 of the occupied caravans. A questionnaire was also used to assess potential factors associated with the recorded levels. Mean formaldehyde levels of 100 ppb in unoccupied caravans and 29 ppb in occupied caravans were recorded. A negative correlation was found between formaldehyde levels and the age of caravans. There were significant seasonal differences in formaldehyde levels measured, with higher levels recorded in winter.
