Molecular Weight of AgentLMW
Agent CategoryOther Chemicals
Specific AgentSulfur dioxide
Occupation Apricot sulfurization workers
Outcome/DiagnosisAsthma-like syndrome
Activity Intervention Pre-treatment with ipratroprium
Participation Rate21 of 21 subjects (Participation rate:100%)
Intervention EffectivenessBaseline lung function tests for all 21 employees were within normal limits. After exposure to sulfur dioxide, without pre-treatment, the mean decrease in forced expiratory volume in one second was .12L. Pre-treatment with ipratropium bromide resulted in a minimized sulfur dioxide-induced response (mean decrease =.04L).
