title: [Occupational health issues at enterprises and utilization of road-building materials derived from the wastes of lead-containing enriched ore from the Aktovrak mines].
abstract: The article presents results of hygienic research assessing use of asbestos materials in road building. Asbestos materials used are waste products of asbestos ore enrichment at Aktovraksky layer (Tuva Republic). The main hazard was proved to be a highly dispersed asbestos-containing aerosol of complex composition, with low content of fiber particles (0.8-1.4%) and respirable fibers (0.25-6%) particularly. The calculated concentrations of asbestos fibers did not exceed the MAC adopted in most countries (1 fiber/ml). Airborne levels of asbestos in road building and exploitation are within the national standard.
