Component Carcinogenicity

ZIRCONIUM SILICATE	10101-52-7
ACGIH:	A4 - Not Classifiable as a Human Carcinogen (related to Zirconium compounds)

Medical Conditions Aggravated by Exposure

respiratory disorders, skin disorders and allergies,

Inhalation - Acute Exposure

ZIRCONIUM SILICATE: May cause irritation The dusts of certain silicates can produce fibrotic changes in the lungs and have been implicated as experimental carcinogens.

Inhalation - Chronic Exposure

ZIRCONIUM SILICATE: Intensive exposure of rats to dust for 7.5 months produced radiographic lung shadows, but no cellular reaction as determined histologically Repeated or prolonged industrial exposure to zirconium compounds has revealed no respiratory or other pathological problems.

Skin Contact - Acute Exposure

ZIRCONIUM SILICATE: Direct contact may cause irritation Some zirconium compounds have caused sensitization and allergic granuloma formation in previously exposed persons The papules generally disappear spontaneously but slowly, persisting for months or years.

Skin Contact - Chronic Exposure

ZIRCONIUM SILICATE Repeated or prolonged contact with similar compounds has caused dermatitis, sensitization reactions, and allergic granuloma, characterized by red-brown papules.

Eye Contact - Acute Exposure

ZIRCONIUM SILICATE: No specific data available Mineral sands may cause irritation with discomfort, tearing or blurring of vision.

Eye Contact - Chronic Exposure

ZIRCONIUM SILICATE No data available.
