Biological monitoring as a valid tool to assess occupational exposure to mixtures of 2,4-:2,6-toluene diisocyanate.

Med. Lav. 103(5) , 361-71, (2012)

Despite its advantages over environmental monitoring, biological monitoring of exposure to 2,4-:2,6-toluene diisocyanate (TDI) mixtures is still underused. The present study was designed in order to e...

Magnetic field dependent electro-conductivity of the graphite doped magnetorheological plastomers.

Soft Matter 11 , 6893-902, (2015)

In this work we reported a novel graphite doped conductive magnetorheological plastomer (GMRP) with magnetic field dependent electro-conductivity. The conductivity of the GMRPs increased by increasing...

LC-MS determination of urinary toluenediamine in workers exposed to toluenediisocyanate.

Toxicol. Lett. 134(1-3) , 259-64, (2002)

To improve the biological monitoring method for 2,6- and 2,4-toluenediisocyanate (TDI) exposure, we developed a simple and rapid method for analysis of the corresponding urinary metabolites, 2,6- and ...
