Special Issue Information

Dear Colleagues,

Exposure estimation and management is an integral part of workplace safety management systems. If excessive or significant exposure cannot be ruled out, for instance, by considering the number of chemicals used, or the concentration of dust-producing substances in machined matrixes, exposure needs to be estimated. Methods of estimating exposure include exposure modeling, biomonitoring, and airway or skin exposure measurements of harmful agents.

The present Special Issue deals with the estimation and management of occupational exposure. The emphasis is on agents that have the potential to cause permanent damage to exposed workers in industrial settings. This includes carcinogens and other mutagens, allergens, and sensitizers, as well as other substances causing potentially life-shortening occupational diseases. Ways of managing the exposure in question should be either established or, at least, discussed.

The aim of this Special Issue is to show that particularly harmful agents commonly present in many occupational settings can be managed with common exposure management methods, without hindering cost-efficient production methods. In fact, when considering all costs of excessive occupational exposure to particularly harmful agents, whether it be the manufacturers or society as a whole, exposure management is beneficial not just from a humane perspective but also from an economical perspective. Therefore, in this Special Issue, the economic realities of suggested exposure management protocols will be discussed with regard to total production costs. Papers presenting descriptions of methods developed to estimate exposure or analyze exposure agents will also be considered, as will reports of methods developed to manage exposure.

When possible, choosing materials with a low quartz content is the most effective and cost-efficient way to prevent the respirable quartz exposure of workers and other end users of powdery products. Therefore, methods are needed to analyze low amounts of quartz from powdery products, such as sand, gravel, plaster, cement, and concrete. To this end, we present a method to analyze respirable dust and quartz from powdered materials, such as construction products. The method includes separation of the respirable dust fraction by liquid sedimentation, followed by gravimetric analysis and determination of the crystalline silica content by X-ray diffractometry. While also aiding in the development of less harmful products, analysis of the quartz concentration of powdery products is statutory in Eu countries, excluding natural products not chemically modified. According to EU Regulation No. 1272/2008, products must be classified if they contain harmful substances in concentrations above 0.1 wt.%, and clauses pertaining to cancerous properties and harmfulness to lungs should be included. Also, mineral producers in the EU recommend that products containing respirable quartz should be labelled based on their quartz concentration, provided the concentration exceeds 1 wt.%. The present method meets these needs. The analysis can be performed in parallel from 50 to 1000 mg (dry weight) of powdery materials. The quantitative limit of determination was 10 µg per sample, corresponding to 0.01 wt.%, and the linear range 0.02–10 wt.% (10–5000 µg quartz per sample, Pearson correlation coefficient 0.99). The accuracy of the method was 82% and the repeatability 11%. Full article
