Nanoparticles: An occupational hygiene review
Nanotechnology is a broad interdisciplinary area of research, development and industrial activity which has been growing rapidly for the past decade. Nanoparticles are the end products of a wide variety of physical, chemical and biological processes. This article reviews the following aspects of nanoparticles: potential routes for human exposure; industrial sources of occupational exposure; level of exposure; means of, and effectiveness of control measures; potential numbers exposed; ease with which gaps in knowledge could be filled; trends in the potential use of nanotechnology; views as to the likely impact of the transition from research to full-scale industrial use.

Determining the physical and chemical nature of ultrafine aerosols, their formation in various manufacturing processes and their behaviour in the human respiratory tract
Aufklärung der physikalischen und chemischen Natur von Feinstaerosolen, ihre Entstehung bei verschiedenen Fertigungsprozessen und ihr Verhalten im Atemtrakt [in German]
This study deals only with particles of a diameter < 0.1µm which cannot be determined by conventional optical and mechanical methods and which, consequently, have not previously been the subject of occupational health studies. Methods and apparatus, in-plant measurements (in particular in plants using high-temperature production processes), analysis of filtered aerosols. A major part of the study is devoted to the evaluation of results obtained in various workshops: steelworks and foundries using electric furnaces and cupola furnaces, LD converter steelworks, fettling and grinding of castings, sulfuric acid pickling of steal sections, electric arc welding, galvanising. The results confirmed the higher incidence of finaly dispersed condensation aerosols, the particles of which initially remain discrete (1-2h) before they become attached to larger particles. The fine particles are therefore deposited in the lower respiratory tract, independentyl of the larger particles.
