“Pennsylvania has opened up its doors to fracking in ways that many other states in the U.S. have not,” said David Dausey, Ph.D., chair of the Mercyhurst University Public Health Department. “We don’t know enough about the environmental and human health effects of fracking and, as a result, Pennsylvania has become the home of experimental fracking.”

This Application Note will demonstrate the extraction of 1,4-Dioxane from an aqueous matrix using Option 1 of EPA Method 522 for 500 mL initial volume sample. It will make use of the SmartPrep Cartridge Extraction System to produce a valid Initial Demonstration of Precision (IDP) and Initial Demonstration of Accuracy (IDA).

Choosing an in vitro model system that faithfully represents the natural physiology of the cell being studied is fundamental to understanding its in vivo function. Cultures of primary cell isolates retain their physiology and karyotype after isolation, but cultures may be difficult to prepare and are susceptible to contamination.
