The goal of this study was to develop a robust method capable of quantifying taste and odor compounds (i.e., geosmin and 2-methylisoborneol) at very low aqueous concentrations in the presence of wastewater and algal derived contaminants. A polydimethylsiloxane/divinylbenzene (PDMS/DVB) fiber was used to perform headspace-solid phase microextraction (HS-SPME) to extract and analyze taste and odor c ...

- ... This work demonstrates the ability of an acetylcholinesterase-inspired biomimetic sensor to accurately predict the toxicity of acetylcholinesterase (AChE) inhibitors. In surface waters used for municipal drinking water supplies, numerous pesticides and other anthropogenic chemicals have been found that inhibit AChE; however, there is currently no portable toxicity assay capable of determining the ...
