P Carbonnelle et al.
The Analyst, 121(5), 663-669 (1996-05-01)
In recent years, epidemiological evidence that exposure to toluene diisocyanate (TDI) is associated with adverse health effects has led to the development of useful analytical methods for the biological monitoring of TDI. In this paper, an HPLC method is presented
G Sesana et al.
American Industrial Hygiene Association journal, 52(5), 183-186 (1991-05-01)
A new sampling system is presented that uses solid sorbent media contained in a tube for the determination of airborne isocyanates (2.4-2.6 toluene diisocyanate, hexamethylene diisocyanate, and 4.4' diaminodiphenylmethane diisocyanate). The method is compared with the National Institute for Occupational
P Maestrelli et al.
Clinical and experimental allergy : journal of the British Society for Allergy and Clinical Immunology, 24(1), 29-34 (1994-01-01)
To assess the nature and the time-course of the cellular component of airway inflammation induced by isocyanates, we examined nine subjects with occupational asthma induced by toluene- or methylene diphenyl-diisocyanate (TDI, MDI) and four control subjects never exposed to isocyanates.
Sébastien Gagné et al.
The Analyst, 128(12), 1447-1451 (2004-01-23)
Isocyanates can cause occupational asthma. By using available HPLC-UVF methods, isocyanates can be quantified only at levels above 1% of the Permissible Exposure Limits (PEL). Once sensitized, workers can react to concentrations below these limits of detection (LOD) making these
B W Day et al.
Chemical research in toxicology, 9(3), 568-573 (1996-04-01)
Guinea pig hemoglobin (Hb) adducts of 2,4- and 2,6-toluene diisocyanate (2,4- and 2,6-TDI) were individually prepared, each at a Hb tetramer to diisocyanate ratio of 1:1, and compared with adducts of Hb from animals exposed to 1 ppm 2,4-TDI vapor.
