Powdering floor polish and mucous membrane irritation in secondary school pupils.
OBJECTIVE
Acrylate-styrene copolymer polish has been used to protect the surface of linoleum flooring since the 1960s. Problems with powdering of floor polish were observed at an early stage. In a secondary school in Linköping, Sweden, this phenomenon occurred in the winter of 1994-1995 and the pupils frequently reported irritative symptoms from the eyes and airways. This study was undertaken to assess the potential effect of powdering floor polish on the mucous membranes of the eyes and respiratory tract.


METHODS
Repeated questionnaire-based surveys were conducted with identical questions in the spring of 1995 (during the powdering period) and in the autumn of 1995 (after the polish was removed). The questions dealt with irritative symptoms from the nose, eye, throat and lower respiratory tract.


RESULTS
A preventive effect related to the removal of polish was found for irritative symptoms in all locations mentioned above, but was particularly clear for the lower respiratory tract (prevalence rate ratio = 0.37, 95% CI = 0.23-0.59).


CONCLUSIONS
The results of this study indicate that the powdering of floor polish may cause irritative symptoms from the eyes and airways in school children.
