Any other information on results incl. tables

The authors reported the results of a 2.5 year study on the
health of workers exposed at a 1,2-dichloro-4-nitrobenzene
processing plant in the former USSR. The workers were
exposed essentially to 1,2-dichloro-4-nitrobenzene,
3,4-dichloroaniline and 3,4-dichloropropionic acid anilide.
The skin was affected (chloracne) and also alterations of
peripheral blood including instable methaemoglobinaemia
appearance of Heinz bodies, a tendency towards
reticulolymphocytosis and thrombocytosis, bilirubinaemia and
dysproteinaemia. The exposure risk was suspected via dermal
absorption due to the low vapour pressure and the working
conditions. Measurements for uncovered skin gave exposures
to 0.002 - 0.2 mg/dm2 1,2-dichloro-4-nitrobenzene and
3,4-dichloroaniline and for covered skin (clothes) 0.0013 -
0.02 mg/dm2.
For 1,2-dichloro-4-nitrobenzene and 3,4-dichloroaniline the
mean individual dermal exposure per shift was given with
2.535 mg, while after cleaning of the skin the mean
individual burden was still 1.066 mg.
Due to the mixed exposure an association of the findings
with exposure to 1,2-dichloro-4-nitrobenzene is uncertain.
