Research and Evaluation of Organic Hazardous Air Pollutant Source Emission Test Methods

Abstract

Title III of the Clean Air Act Amendments of 1990 has increased the need for well defined and tested stationary source emission sampling and analysis methods. The Methods Branch of the Air Measurements Research Division of U.S. EPA' s Office of Research and Development is responsible for a major methods development and evaluation program intended to help fill that need. This paper summarizes recent developments from several of the component projects of that program. Primary emphasis is placed on status and references for methods for organic hazardous air pollutants, such as phosgene, methanol, chloroform, acetonitrile, isocyanates, aldehydes, halogenated organics, non-halogenated organics, and volatile organic material

Environmentally Sustainable Achiral and Chiral Chromatographic Analysis of Amino Acids in Food Supplements

“…Owing to its low viscosity, complete miscibility with water and low UV absorption, ACN is still the most widespread organic modifier for RP-HPLC applications, also when used in combination with IP reagents. However, in spite of all these favorable characteristics, its well-recognized acute toxicity (both dermal and oral), flammability, and volatility, besides its inclusion in the list of hazardous air pollutants [22], has stimulated many researchers worldwide to find valuable alternatives in compliance with the main paradigms of sustainable development. This tendency was further fueled by the global shortage of ACN in 2009 [23].…”
