Occupational asthma due to zinc.
We describe a subject who developed asthma symptoms 2 yrs after being employed at a plant where metals were galvanized in heated zinc.
The subject was not atopic.
Baseline spirometry was normal three months after he left work but there was mild bronchial hyperresponsiveness to methacholine.
Monitoring of forced expiratory volume in one second (FEV1) during a day at work showed a maximum fall in FEV1 of 24% at the end of the day and an increase in bronchial responsiveness on the following day.
Environmental monitoring revealed that zinc and iron were present in the working environment at concentrations that were lower than the « threshold limit value - short term exposure level » (TLV-STEL) standards.
