The consumer product safety commission and nanotechnology
During the fall of 2007, many Americans faced a hazard in their products that had been banned for 30 years—lead. As millions of children’s toys were recalled, it became clear that government oversight had failed, and that the agency primarily responsible for the oversight of these toys— the US Consumer Product Safety Commission (CPSC)—was stretched too thin from years of neglect, underfunding and the challenges posed by an increasingly global manufacturing system. It is against this background that ... |

Air emissions of ammonia and methane from livestock operations: Valuation and policy options
The animal husbandry industry is a major emitter of ammonia (NH3), which is a precursor of fine particulate matter (PM2.5) —arguably, the number-one environment-related public health threat facing the nation. The industry is also a major emitter of methane (CH4), which is an important greenhouse gas (GHG). We present an integrated process model of the engineering economics of technologies to reduce NH3 and CH4 emissions at dairy operations in California. Three policy options are explored: PM offset ... |

Complete Solutions for Pesticide Residue Analysis in Foods -
From sample preps to HPLC and GC analysis with MS/MS detection
Pesticides are widely used in many areas of modern agriculture as they are considered economically important for high yield production. In today’s world of extensive importing and exporting of food goods, the analysis and monitoring of pesticides is essential, although challenging. The determination of an effective, standardized approach for extracting pesticides from food sources and subsequent identification of compounds can be considerably problematic. To overcome these challenges, Varian offers a complete support solution for the extraction, isolation, identification and quantitation of pesticide residues, from sample preparation to reporting of results.
