Health hazards

powder mixture) May cause skin and eye irritation. May cause irritation of the upper respiratory tract (nose, mouth and/or throat), resulting in sneezing coughing and sore throat. Long-term respiratory exposure exceeding exposure limits may damage the lungs, leading to impairment of lung capacity. The acute and chronic health effect statements below are for the pure chemicals only, unless noted.

Potential Acute Health Effects

CARBON BLACK) May be irritating to the eye & cause conjunctivitis. Prolonged or repeated skin contact may cause irritation. (BARIUM SULFATE) Inhalation of dusts containing barium sulfate may be irritating to the respiratory tract. Contact with the eyes may also cause irritation. In 1994, US EPA deleted barium sulfate from the category "barium compounds" on the list of toxic chemicals for which reporting is required. The final rule is in 40 CFR Part 372.

Potential chronic health

CARBON BLACK) In 1978, NIOSH concluded that "carbon black may cause adverse pulmonar & heart changes" & "may pose a cancer risk" due to absorbed polycyclic hydro-carbons. Studies have not shown a significantly increased circulatory malignant or respiratory morbidity among carbon black workers in the U.S. Prop 65 "This chemical is known to the state of California to cause cancer" (BARIUM SULFATE) Prolonged exposure could cause benign pneumoconiosis called Baritosis.
