| Polychlorinated dibenzo-p-dioxins (dioxin) are a category of toxic halogentated aromatic hydrocarbons inadvertently introduced into the environment. Dioxins are typically formed by the incineration of coal, waste, wood and other fuel sources as well as the burning of polyvinyl chloride (PVC) piping. These toxins are emitted into the atmosphere as exhaust particles that deposit onto our soil and grass. From here, dioxins are eventually introduced into our beef supply from grazing cattle and it accumulated in the fatty tissues of these animals. The intent of this research is to deposit minute quantities of dioxin, in the laboratory, into store purchased meat (s) via the combustion of PVC piping and identify it using a state-of-the-art 400 MHz NMR spectrometer. Dioxin was extracted from the meat using cyclohexane. 1H NMR spectra of the extracts were acquired to determine whether dioxin(s) has been absorbed in the meat. Resonance peaks in the region from 7.00 to 7.4 ppm's verify the presence of dioxin in the meat product. The dioxin 2, 3, 7, 8-tetrachlorodibenzo-p-dioxin (2, 3, 7, 8-TCDD) serves as a reference material in this work. |
