CASSEN Testing Laboratories will be presenting the following 2 papers at the EnviroAnalysis 2013 Conference (September 13 – 15, 2013) in Toronto
1) Approaches to Investigating the Sources of Airborne Organic Compounds from Industrial Emissions
Industrial activities show a significant contribution to VOCs emissions which play an increasingly important role in affecting the air quality. It has been a rapidly evolving issue that has been receiving substantial attention in the past two decades. The VOC profiles have also changed over time as more new industrial compounds are being introduced which are outside the regulatory definition of VOCs. The most often asked questions in environmental monitoring are: what are these VOC contaminants; and where did they originate from. Accurate characterization of different air pollutants can be challenging, therefore understanding the industrial processes involved, expected release and discharge will be useful in understanding the sources of the emission, as well as distinguish the contaminants from naturally occurring to anthropogenic origin. In order to obtain a better understanding of industrial VOCs emissions, several major industries will be included in this presentation, which examines the potential airborne chemicals used in each industry as well as by-products generated.
2) An Efficient Technique for the Determination of Volatile Methylsiloxanes in Air
Volatile methyl siloxanes (VMS) including the linear and cyclic compounds have widespread use in commercial and personal care products and as a result are prevalent in the air of many different public environments including workplaces, schools and residential homes. The concentrations of certain linear and cyclic VMS in these settings can reach into the mid-ppb range. Currently there are no established threshold limits for VMS, as they are generally not deemed toxic substances, although there have been reports on various VMS adversely affecting human endocrine, immune and nervous systems. Therefore, an accurate and highly sensitive means to monitor VMS exposure may be warranted. Numerous methods such as canisters, midget impingers, SPME, etc., have been used to collect VMS in air but all are not without their inherent limitations, such as poor recovery, contamination and low sensitivity. This presentation discusses a simple, yet effective alternative method to collect and analyze VMS in air.
