Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Epidemiological data
Administrative data
- Endpoint:
- epidemiological data
- Type of information:
- migrated information: read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- other information
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Absence of control group, incomplete description of exposure and possibility for healthy worker effect severely restrict extrapolation

Results and discussion
Any other information on results incl. tables
RS-Freetext:
General medical screening, lung function tests, blood
pressure, skin condition, gastro-intestinal functioning,
serum sodium, calcium, potassium chloride and sulfate
content were all within normal ranges ( i.e presumably as
found in the general population).
Mean urinary excretion of inorganic sulfate exceeded 2.2
gr/liter in all workers and thirty percent of the workers
excreted more than 3 gr of inorganic sulfate per day,
indicating massive uptake from recent exposure. The only
subjective symptom indicated by the workers was nasal
irritation and runny noses on exposure to dust.
Internal sub-cohort study:
Short exposure duration subcohort:
subjects: More than 10 years of exposure (n=77)
age 28.0 +-10,
exposure duration 3.1 + 2.8 years
Long exposure duration subcohort:
Subjects: more than 10 years exposure (n=42)
age 454.5 + 8.8,
exposure duration 19.9 + 3.6 years
Results:
No differences other than explained by age difference.
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
