The observations showed that lead-containing surma consists of fine particles of galena (ore of lead sulfide) in a respirable dust range (less than 10 μm), and relative in vitro bioavailability of lead in the surma was determined as 5.2%. Thus, lead-containing surma consists of inhalable and bioavailable particles, and it contributes to an ...
