1. Isocyanates - assessment of human exposure
Abstract : Isocyanates are used mainly for manufacturing of polyurethane (PUR) foams, lacquers, elastomers and glues. The production of PUR exceeds 2 million tonnes per year and is increasing. Occupational exposure to isocyanates are associated with respiratory disorders. READ MORE

2. Biomarkers of aromatic isocyanates in exposed workers
Abstract : The aromatic isocyanates, toluene diisocyanate (TDI) and methylenediphenyl diisocyanate (MDI), are used in the production of polyurethane (PUR) foams, paints, elastomers and glues. The use of isocyanates is increasing, and exposure to isocyanates is the most common cause of occupational asthma. READ MORE

3. Development and Evaluation of a Denuder-Filter System Designed for Sampling Diisocyanate Aerosols
Abstract : There are many occupational environments in which isocyanates or PUR-products are used, produced or processed. During these operations there is always a risk of isocyanate exposure, which may lead to severe health problems. Isocyanates principally affect the respiratory system and they are the main cause of occupational asthma. READ MORE

4. Experimental and Clinical Studies on Contact Allergy to Diphenylmethane-4,4′-diisocyanate and Related Substances
Abstract : The exposure to isocyanates is more of an occupational problem than a consumer problem. The main route of exposure is assumed to be through inhalation. Isocyanates that have high vapor pressure, such as TDI, can be airborne at room temperature. Other isocyanates such as MDI are volatile only when heated. READ MORE

5. Chemical and Clinical Studies of Isocyanate Contact Allergy with focus on diphenylmethane diisocyanate
Abstract : Isocyanates are highly reactive compounds used in the production of polyurethane. Exposure to isocyanates is mainly associated with respiratory disorders, but may also result in allergic contact dermatitis. Reports describing contact allergy to isocyanates are few in number and it has been considered a rare phenomenon. READ MORE
