In this research experiment Ethylene Vinyl Acetate (EVA) is used to analyze organic pollutants in the environment. EVA is an effective polymer for analyzing pollutants due to its high affinity towards organic compounds and its ability to be spread to sub-micron film thickness on various materials. Various indoor and outdoor environments were studied using EVA on glass substrates and silicon wafers substrates. After the EVA samples were exposed to environmental pollutants for several weeks. Gas Chromatography Mass Spectrometry (GC-MS) was used to analyze the EVA on glass substrates by first extracting the chemical pollutants with methanol and then direct injection into the GC-MS. The surface characterization of the silicon wafers were studied using Atomic Force Microscopy (AFM).
