    About the Event

    Papers are invited for the Third ASTM Symposium on Silica and Associated Respirable Mineral Particles to be held October 29-30, 2020. Sponsored by ASTM Committee D22 on Air Quality, the symposium will be held at the Renaissance Orlando at SeaWorld in Orlando, FL, in conjunction with the October standards development meetings of the committee.


    Crystalline silica accounts for 12% by weight of the earth’s crust and is present in most rock and soils and many construction materials. Chronic and acute respiratory disease associated with occupational exposure to airborne respirable crystalline silica (RCS) has been observed through history and, currently, there is no effective treatment. Therefore, it is essential to understand the working environments where silica dust is present in order to take all necessary precautions for workers’ health.

    Improving and standardizing analytical methodologies across laboratories and countries and developing samplers that provide additional RCS mass for analysis is required to address this situation. Combining these two approaches will allow accurate evaluation of workplace concentrations of RCS and has the potential to allow shorter-term task-based sampling for better understanding of the determinants of exposure. This Symposium builds on the work presented at the first and second ASTM Silica Symposia held in 2004 and 2012 and provides an update on progress towards accurately assessing RCS exposures for compliance with limit values and beyond compliance for improved worker protection. It will be valuable to regulators and bodies which set guidance for RCS exposures, managers and technicians of laboratories engaged in RCS analysis, hygienists and others collecting samples for RCS, risk assessors and managers engaged in determining and managing the risks of products or processes that may result in emission of RCS, and representatives of workers exposed to these products and processes.

    Symposium paper topics of all aspects of sampling and analysis of airborne respirable dust generally or respirable crystalline silica specifically are invited and may include:

    • development, implementation, quality assurance and validation of existing or novel samplers
    • direct and indirect sample preparation procedures
    • analytical methods (gravimetric, colorimetric, infra-red absorption or x-ray diffraction)

    The language of the symposium will be English.

    Abstract Submittal

    To participate in the symposium, authors must submit a 300-word preliminary abstract using the online Abstract Submittal Form no later than February 28, 2020. The form can also be accessed by scrolling to the top of the page and clicking “Go to Abstract Submittal Form”. To ensure your abstract was received into the ASTM database, please email and let us know that you have submitted an abstract.

    The abstract must include a clear definition of the objective and approach of the work discussed, pointing out material that is new, and present details regarding results. The presentation and manuscript must not be of a commercial nature nor can it have been previously published. Because a limited number of abstracts will be accepted, be sure that the abstract is complete to allow for careful assessment of the paper's suitability for this symposium. Symposium Chairmen Martin Harper and Emanuele Cauda will notify you via postal mail by March 27, 2020 of your paper’s acceptability for presentation at the symposium. If the preliminary abstract is accepted, the presenter/author will be requested to submit a final camera-ready abstract several months before the symposium. The final abstracts will be distributed in an abstract booklet at the symposium.


    Symposium presenters are requested to submit their papers to the Selected Technical Papers (STP), an online and printed, peer-reviewed publication for the international scientific and engineering community. After the final selection of abstracts has been approved, the ASTM Editorial Office will send authors’ instructions via email only. Manuscripts to be peer reviewed for the STP are due online no later than October 16, 2020 at the ASTM Editorial Office. The corresponding author (the author who is the main contact with ASTM Headquarters) will receive a copy of his/her paper in portable document format (PDF). All published authors will have the opportunity to purchase reprints of their papers at a nominal cost. Only those papers submitted by the manuscript due date will be included in the STP.

    Please note that all submitted papers are subject to single blind peer review and will be submitted to the Library of Congress with an ISBN number and will be reviewed for inclusion in the Web of Science Conference Proceedings Citation Index" (CPCI) and Google Scholar.
