Newly Published Journal Article on Compounds Found in Crumb Rubber

NEW HAVEN, Conn., April 18, 2018 /PRNewswire/ -- Environment and Human Health Inc. (EHHI), an organization of physicians and public health professionals, announces the publication of a journal article on the compounds found in crumb rubber. The article is the result of the chemical analysis done at Yale University that was supported by a grant from the Forrest and Frances Lattner Foundation to Environment and Human Health Inc.

The newly published Journal article was researched and written by Gaboury Benoit, Ph.D., the Grinstein Professor of Environmental Chemistry at Yale's Environment School. The article is published in the Journal of "Water Air Soil Pollution" (2018) 229: 64.

Journal article
"Evaluation of Organic and Inorganic Compounds Extractable by Multiple Methods from Commercially Available Crumb Rubber Mulch"

Abstract
Recycled tires are often shredded for use in a variety of consumer-related products. The rubber so used may contain a number of compounds known to be deleterious to human and environmental health. We obtained nine samples of shredded tire material sold over the counter to the general public for home use, as well as six samples used for infill in synthetic turf athletic fields. After thorough cleaning and grinding, samples were extracted with either organic solvent (dichloromethane), strong acid, or simulated acid rain, or allowed to degas passively. Compounds released by these multiple methods were then identified, and in some cases quantified. Solvent extraction yielded 92 separate compounds, of which only about half have been tested for human health effects. Of these, nine are known carcinogens and another 20 are recognized irritants, including respiratory irritants that may complicate asthma. Strong acid extraction released measurable amounts of Pb and Cd and relatively large amounts of Zn. These three metals were specifically targeted for analysis, and others may be present as well, but were unmeasured. Simulated acid rain extracted only Zn in significant quantities. Passive volatilization yielded detectable amounts of 11 compounds. Results demonstrate that recycled tire materials contain and can release a wide variety of substances known to be toxic, and caution would argue against their use where human exposure is likely.
