Methylcyclohexane methanol (MCHM) is the chemical that leaked into the Elk River, in Charlestown, West Virginia on the 9th of January, 2014, causing state of emergency called for use of drinking water contaminated with the chemical. Methylcyclohexane methanol is an organic compound classified as a saturated higher alicyclic primary alcohol. It is commonly used in air fresheners and as frothing agent for coal processing and cleaning. The full toxicity of this chemical to humans was unknown at the time of spill and there is still lack of information on exact toxic effects of the crude MCHM. In a recent study …
Effect Of Silver Nanoparticles On Select Soil Enzyme Activities Involved In Nutrient Cycling, William Doggett, Frieda Eivazi, Zahra Afrasiabi, L. Jose

Soils are being continuously exposed to large amounts of engineered nanoparticles (ENPs), especially silver nanoparticles (AgNPs). These materials can interact with microbial enzyme activity, stability and/or specificity affecting their role in nutrient cycling. Specific enzyme activity measurements have potential to serve as bioindicator in identifying major changes in the soil environment. Present study investigated the effect of AgNPs on soil enzymes known to play a critical role in mineralization of C, N, P and S in the soil. Soil samples were collected from surface layer (0-10 cm) of a Wrengart silt loam series. The study used two sizes (10 and …
