EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion. Effects of short-term exposure The substance is severely irritating to the eyes, skin and respiratory tract. The substance may cause effects on the gastrointestinal tract and kidneys. This may result in tissue lesions and kidney damage. Medical observation is indicated.	Inhalation risk A harmful concentration of airborne particles can be reached quickly when dispersed. Effects of long-term or repeated exposure Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the kidneys, central nervous system and peripheral nervous system. This may result in ataxia, sensory and memory disturbances, tremors, muscle weakness and kidney impairment. The substance may have effects on male fertility. May cause heritable genetic damage to human germ cells. See Notes.

OCCUPATIONAL EXPOSURE LIMITS
TLV: (as Hg): 0.025 mg/m³, as TWA; (skin); A4 (not classifiable as a human carcinogen); BEI issued. EU-OEL: (as Hg): 0,02 mg/m³ as TWA. MAK: (as Hg, inhalable fraction): 0.02 mg/m³; peak limitation category: II(8); skin absorption (H); sensitization of skin (SH); carcinogen category: 3; pregnancy risk group: D

ENVIRONMENT
The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur in aquatic organisms. The substance may cause long-term effects in the aquatic environment. It is strongly advised not to let the chemical enter into the environment.

NOTES
Depending on the degree of exposure, periodic medical examination is suggested. Do NOT take working clothes home. Due to lack of specific data on this substance, the information included in this card was derived by analogy with other mercury(II) compounds.
