[A new method for determination of toluene-2,4-diamine and toluene-2,6-diamine in workplace air].
BACKGROUND Toluenediamines are harmful substances. Toluene-2,4-diamine has been assigned to Carcinogen 1B hazard class, pursuant to Regulation (European Community - EC) No. 1272/2008 of the European Parliament and of the Council, and toluene- 2,6-diamine to Mutagen 2 hazard class. The main routes of exposure to toluene-2,4-diamine and toluene-2,6-diamine are via the respiratory tract and the sk...
متن کاملTwo decades of p-phenylenediamine and toluene-2,5-diamine patch testing - Focus on co sensitizations in the European baseline series and cross reactions with chemically related substances.: PPD and TDA co sensitizations and cross reactions
Background. Cross-reactions and co-sensitizations are of great importance in understanding contact allergy and exposure sources. Objectives. To investigate common cross-reactions and co-sensitizations in p-phenylenediamine (PPD)-sensitized and toluene-2,5-diamine (TDA)-sensitized individuals. Methods. Fromour patch test population, 8036patients patch testedwith the European baseline series were...

متن کاملNew Thermally Stable Aromatic Polyimides Based on Aromatic Diamine 2,5-Bis(3-amino-4-methyl benzene)-1,3,4-oxadiazole (BAMO): Synthesis and Characterization
In current study, the synthesis and characterization of novel thermally stable polyimides (PIs) containing an 1,3,4-oxadiazole moiety based on a diamine, i.e. 2,5-bis(3-amino-4-methyl benzene)-1,3,4-oxadiazole (BAMO), have been reported. The polymers were characterized using FT-IR and elemental analysis (CHN). Thermal and mechanical behaviours of the prepared PIs were studied by thermo-gravimet...
متن کاملContact Allergy to Hair Dyes
Many strong and extreme sensitizing chemicals, such as para-phenylenediamine (PPD), toluene-2,5-diamine (TDA) and other aromatic amines or cross-reacting substances, are ingredients in hair dye products. The chemistry of hair dyeing and the immunological reactions to the potent sensitizing hair dye components are complex and have not been fully clarified up until now. Recently 2-methoxymethyl-p...
