Título Polyvivnyl chloride processing technology and lead contamination of the working environment
Título original Tecnologia di trasformazione del cloruro di polivinile e relativo inquinamento da piombo nell'ambiente di lavoro [en italiano]
Información bibliográfica July-Aug. 1981, Vol.48, No.4, p.379-388.
Resumen The chemical reaction of PVC polymerisation is described and a review is given of the various additives used to modify the characteristics of the final polymer: stabilisers, plasticisers, lubricants and pigments. Stabilisers and pigments may contain lead, and the mixing of the dry-blend of PVC granules and these additives may give rise to high atmospheric lead contamination. The mixing process is described and a report is given on studies to monitor atmospheric lead concentrations at various parts of a PVC plant over the years 1971 to 1979. The highest concentrations were encountered in the dry blending process; these concentrations have been reduced by industrial hygiene measures, in particular local exhaust ventilation.
