Hemoglobin adducts in workers exposed to nitrotoluenes.
Nitrotoluenes are important intermediates in the chemical industry. 2,6-Dinitrotoluene (26DNT), 2,4-dinitrotoluene (24DNT) and 2-nitrotoluene are carcinogenic in animals and possibly carcinogenic in humans. It is therefore important to develop methods to biomonitor workers exposed to such chemicals. Hemoglobin (Hb) adducts of nitroarenes are established markers of the biological effective dose....
متن کاملHemoglobin adducts in workers exposed to benzidine and azo dyes.
Benzidine (Bz) is a known human carcinogen. Several azo dyes have been synthesized with Bz. Bz can be metabolically released from azo dyes. In a group of Indian workers producing Bz and azo dyes the presence of hemoglobin (Hb) adducts was investigated. The following Hb adducts were identified and quantified by GC-MS: Bz, N-acetylbenzidine (AcBz), 4-aminobiphenyl (4ABP), aniline. 4ABP and anilin...
متن کاملDetermination of albumin and hemoglobin adducts in workers exposed to styrene and styrene oxide.
Hemoglobin and albumin adducts of the carcinogen styrene-7,8-oxide (SO) were measured in 48 workers exposed to both styrene and SO in a boat manufacturing plant. Personal exposures to both substances were measured repeatedly over the course of 1 year (styrene:0.9-235 mg/m3 with a mean of 64.3 mg/m3 for 48 subjects; S0: 13.4-525 mu g/m3 with a mean of 159 mu g/m3 for 20 subjects). Cysteine and c...
متن کاملHemoglobin and albumin adducts of benzene oxide among workers exposed to high levels of benzene.
Benzene oxide (BO) reacts with cysteinyl residues in hemoglobin (Hb) and albumin (Alb) to form protein adducts (BO-Hb and BO-Alb), which are presumed to be specific biomarkers of exposure to benzene. We analyzed BO-Hb in 43 exposed workers and 42 unexposed controls, and BO-Alb in a subsample consisting of 19 workers and 19 controls from Shanghai, China, as part of a larger cross-sectional study...
متن کاملCharacterization and comparative analysis of 2,4-toluene diisocyanate and 1,6-hexamethylene diisocyanate haptenated human serum albumin and hemoglobin.
Diisocyanates (dNCOs) are low molecular weight chemical sensitizers that react with autologous proteins to produce neoantigens. dNCO-haptenated proteins have been used as immunogens for generation of dNCO-specific antibodies and as antigens to screen for dNCO-specific antibodies in exposed individuals. Detection of dNCO-specific antibodies in exposed individuals for diagnosis of dNCO asthma has...
