Isocyanates (metabolites: 2,4-TDA and 2,6-TDA), urine

Modification and extension test results

Test code: 3429

Effective update from 11/05/16




PREVIOUS

NEW
Isocyanates (metabolites: 2,4-TDA and 2,6-TDA), urine      

  
People exposed to TDI (toluene diisocyanate)
Indicative way, at the end of the day labor
       
2,4-TDA (toluene 2,4-diamine): 2.8 - 9.6 mg/g creatinine
2,6-TDA (toluene diamine-2,6): 5.6 - 16.6 mg/g creatinine
       
The relationship between urinary concentration of TDA and health effects is not established, so these values are useful only as indicators of level of exposure
     
     
     
     
     

Isocyanates (metabolites: HDA, 2,4-TDA, 2,6-TDA and MDA), urine        
         
People exposed to HDI (hexamethylene diisocyanate 1,6)
Indicative biological limit value at the end of the workday

HDA (1,6-hexamethylene diamine): 17.5 to 52.6 mcg/g creatinine

People exposed to TDI (toluene diisocyanate)
Indicative biological limit value at the end of the workday

2,4-TDA (toluene diamine-2,4): 2.8 to 9.6 mcg/L
2,6-TDA (toluene diamine-2,6): 5.6 to 16.6 mcg/L

People exposed to MDI (4,4-methylene diphenylisocyanate)
biological limit value (BLW-DFG) at the end of the workday

MDA (4,4-methylene dianiline): 10.0 mcg/L

Amines are analyzed metabolites appear in the urine of people exposed to the corresponding diisocyanate (HDI, TDI, MDI).

The relationship between urinary concentration of HDA and TDA and health effects is not established, so these values are only useful as indicators of level of exposure.
