Non-invasive break-up time (NIBUT) and self-reported break-up time (SBUT) measured in seconds among men and women (18-67 years) in three exposure groups related to an explosion causing environmental pollution

*UI = Unexposed inhabitants far from the explosion area
*EI = Exposed inhabitants near the explosion area
*EW = Exposed workers at the explosion area
† Significant differences between workers and inhabitants near pollution and also between workers and inhabitants far from pollution, Wilcoxon-Mann-Whitney-test, with exact p-values; p = 0.001 for both comparisons.
