occupational illnesses are grossly underfunded and understaffed. This investigation illustrates not solely that occupational well being problems exist in Taiwan, but they can usually be remedied with minimal price to business. The key to bettering occupational well being among workers in Taiwan and elsewhere is to ascertain higher procedures for licensing and inspecting factories and to coach physicians and industrial hygienists to conduct correct well being hazard evaluations and implement environmental control measures. During September-November, 1985, 4 workers of a manufacturing facility in Taipei County were seen in an outpatient clinic of the National Taiwan University Hospital complaining of cough, shortness of breath, chest tightness, and wheezing. The signs tended to be worse at night time and improved after long holidays. All 4 workers labored in the identical space in the manufacturing unit the place an adhesive was applied to the velcro-like tape through the manufacturing process. A review of all of the processes found that the adhesive resin contained toluene diisocyanate , a widely known cause of occupational bronchial asthma [NIOSH, 1978; Chan-Yeung and Lam, 1986; NIOSH, 1977b]. Because TDI-induced occupational asthma has by no means, to our data, been documented in Taiwan, this research was performed to determine the etiology and prevalence fee of this outbreak of staff’ bronchial asthma. Biological exposure indices are reference values established by ACGIH which are supposed as tips for evaluating potential publicity hazards in the workplace. The BEI for the urinary metabolite of toluene is 5 g/g creatinine; the pattern is collected on the end of the work shift. Hippuric acid can be a metabolite of different aromatic solvents and certain endogenous agents; therefore, it isn’t specific to toluene. The BEI for toluene in venous blood, collected on the finish of the work shift, is 0 mg/L; whereas the toluene index in end-exhaled air , measured during the work shift, is 20 ppm. These biologic standards are helpful as confirmatory tests for the effectiveness of office industrial hygiene practices but not for comparability in instances of acute exposure. There is not any specific scientific remedy for patients who’ve been chronically uncovered to toluene. Sources of publicity should be recognized and minimized. Intentional unstable-solvent abusers should be referred to applicable treatment packages to encourage abstinence. If a big ingestion of toluene is suspected or if respiratory distress develops after acute inhalation exposure, hospital admission, chest radiography, spirometry, willpower of arterial blood gases, and monitoring of important signs are beneficial. Acutely uncovered sufferers who’re asymptomatic and have a adverse chest X ray don’t require further hospital remark. Toluene has been implicated in adverse developmental effects that have occurred in offspring of chronic toluene abusers.
