Title Incidence of chromium-induced lesions among electroplating workers in Brazil.
Bibliographic information Dec. 1972, Vol.41, No.12, p.21-25. 15 ref.
Abstract A survey was carried out among workers in Sao Paulo, exposed to chromic acid in its hot and cold states. Within a group of 303 electroplaters in the State of Sao Paulo, 86.8% showed lesions due to chromic acid either in solution or vapour form. The threshold limit value of 0.10 mg of CrO3/m3 was exceeded in the majority of undertakings using hot chrome baths. Collective protective equipment when installed and individual protective equipment when provided were not used routinely because of lack of sanitary education not only of the workers, but also of the industrialists.
