Abstract(summary):

Dimethylformamide (DMF) is a broad solvent used in the production of synthetic leather. Decades of year's research have been focused on workers in leather factories suffering from the release of DMF. However, little attention was paid on general population. Here, we examined the relationship between consistent DMF exposure and annual hospitalizations of local residents in Longwan, China, in 2008. We found a positive correlation with a relative risk (RR) increase of 1.110 for total hospitalizations. When the data were stratified by sex, we observed a higher correlation for female hospitalizations than for male hospitalizations, with RR values of 1.55 and 1.084, respectively. This might be attributed to the differences in genotypes of oxidant enzyme between gender. The significance of the correlations did not disappear after we excluded the extreme value of DMF or adjusted for SO2, NO2, and PM10. Population living near the leather factory has experienced almost constant DMF exposure, and real concern should be raised regarding such exposure. Governments should take responsibility for the protection of not only occupational workers but also residents, especially women.
