Description	Lead wastes are melted in the complex of Kovohutě Příbram nástupnická, a.s., mostly from discarded (broken) lead starter accumulators. Burning of coke in a charge inside a blast furnace causes melting of lead and its reduction. The melting is continually discharged into a siphon and subsequently tapped into moulds. Measurements of distribution of nano- and micro-particle were performed during the described operations. Meanwhile, the particles were collected on filters to analyse their shapes and chemical compositions; we also measured efficiency of regular respirators. Spherical, cubic, cuboid, cylinder and amorphous particles were found, with the prevailing composition of Pb and PbS alloys. However, the atmosphere in the furnace proximity contained also particles of other heavy metals that are considered high-risk elements from the viewpoint of toxicity. The work also includes a discussion about toxicity and how it is affected by composition and shape of the particles.
