Chronic pulmonary function loss from exposure to toluene diisocyanate 1

In 1972 a total of 112 workers exposed to toluene diisocyanate (TDI) were examined for acute pulmonary function changes during a work shift on the first day of the working week. A dose-response relationship was demonstrated for the acute effects of TDI in this population. The cohort was restudied in 1974 to determine whether there was excessive loss of pulmonary function, and if so, whether the...

[Cohort studies of effects of long-term toluene diisocyanate (TDI) exposure on pulmonary function].

Toluene diisocyanates (C6H3CH3 (NCO)2, TDIs) are synthetic low molecular-weight organic chemicals with two highly reactive isocyanate groups (-NCO). Exposure to TDI can cause irritation of the eyes, nose, and upper and lower respiratory tract, asthma-like responses, sensitive pneumonitis, and obstructive pulmonary function loss. In this paper, the exposure-effect relationships between long-term...

Reference exposure levels for toluene diisocyanate

The Office of Environmental Health Hazard Assessment (OEHHA) is required to develop guidelines for conducting health risk assessments under the Air Toxics Hot Spots Program (Health and Safety Code Section 44360 (b) (2)). OEHHA developed a Technical Support Document (TSD) in response to this statutory requirement that describes acute, 8 hour and chronic RELs and was adopted in December 2008. The...

Pulmonary effects of short-term exposure to low levels of toluene diisocyanate in asymptomatic subjects.

Isocyanates may be involved in the development of chronic obstructive airway disease among exposed workers. A short-term exposure to toluene diisocyanate (TDI) at concentrations near the permissible levels was investigated to examine whether there was an association with changes in pulmonary function tests and in potential markers of airway injury and inflammation in bronchial lavage (BL) and b...
