Vermiculite is a mineral, similar to mica, which, after being mined, is milled into ore of various sizes and grades. The ore is then expanded by being heated and popped to produce a lightweight product that is used in industries such as construction, agriculture, horticulture, and wherever insulation is needed. The vermiculite product has the shape of small pleated pellets and is usually a golden brown metallic color. Vermiculite ores often contain a range of other minerals including, in some cases, asbestos. Vermiculite became a health concern after significant levels of asbestos were found to be in some of the same soils in which vermiculite occurs. Of particular concern was vermiculite produced by the Libby mine in Colorado. Asbestos is not a major contaminant, and only a few ore deposits have been found to contain more than trace amounts of asbestos minerals. However, exposure to airborne asbestos particles has been linked to respiratory ailments, specifically mesothelioma, and EPA is concerned about the increased risk to consumers and workers from use of asbestos-contaminated vermiculite products.
