    Chronic Effects on Humans
    Excreted in maternal milk in human.
    Special Remarks on other        Acute Potential Health Effects:    
    Toxic Effects on Humans        Skin: May cause skin irritation. It may be absorbed through the skin.    
    Eyes: Dust may cause eye irritation.
    Inhalation: Dust may cause respiratory tract irritation.
    Ingestion: May cause gastrointestinal tract irritation. May also affect behavior (toxic psychosis), metabolism
    (anorexia), and urinary system. This material is readily absorbed from the gastrointestinal tract. Ingestion of a
    massive single dose is unlikely to cause adverse effects.
