  • Ethylene oxide – useful but dangerous?

    We’re proud of the fact that Analox Sensor Technology can help you monitor a wide range of gases, from carbon dioxide and carbon monoxide, to oxygen and helium. One of the more unusual gases we offer monitoring solutions for is ethylene oxide, or C2H4O as it is often known. Many people do not know what ethylene oxide is, and we have seen a lot of Google searches where people ...

  • Monitoring Ethylene (C2H4) and Carbon Dioxide (CO2) in Ripening Rooms

    As fruit and vegetables ripen, they release ethylene, a naturally occurring growth hormone. To be profitable and meet demands, commercial fresh produce companies need to speed up the ripening process in a uniform and predictable way, which is achieved by adding more ethylene in a controlled environment. Typically the fresh produce is placed in air-tight ripening rooms and ethylene is introduced ...

  • Greenhouse gas reporting in the ethylene manufacturing sector

    Abstract The Greenhouse Gas (GHG) Mandatory Reporting Rule (MRR), codified in Part 98 of Title 40 of the Code of Federal Regulations, requires numerous manufacturing sectors including ethylene manufacturing plants in the U.S. to report actual GHG emissions from applicable facilities starting with reporting year 2010. This paper describes the types of GHG emission sources at ethylene ...

  • Chemical Industry: Compliance problems solved by Ethylene Oxide Scrubber at Specialty Gas Plant Chemical Industry The ethylene glycol produced in the ethylene oxide scrubbing operation acts as an antifreeze to allow year-round operation

    Problem: A specialty gas producer was confronted with an EPA compliance problem in dealing with ethylene oxide (EtO). The chemical had been added to the toxicity lists of the U.S. EPA and the Occupational Safety and Health Administration (OSHA). Effective August 21, 1984, the OSHA standard for EtO limited exposure to a 1 ppm, eight-hour time weighted average. Ethylene ...

  • Monitoring organophosphorus pesticides and their degradation products formed by Fenton's reagent using solid-phase extraction–gas chromatography–mass spectrometry

    Styrene-divinylbenzene co-polymer (PLRP-S) has been found to be a suitable sorbent for the extraction of organophosphorus pesticides (OPPs) and their decomposition products formed by reaction with the Fenton reagent. The preconcentrated analytes have been eluted with ethyl acetate and analysed by GC-MS. A linear calibration graph was obtained for 0.5–40 µg L-1 of OPPs using 60 ml of sample ...

  • Analysis of gene expression profiles in largemouth bass exposed to 17-beta-estradiol and to anthropogenic contaminants that behave as estrogens.

    Novel molecular based methods are being developed to study changes in gene expression in wildlife exposed to anthropogenic chemicals. Gene arrays, in particular, are useful tools that can be used to simultaneously monitor hundreds to thousands of genes within a single experiment, giving an investigator the ability to determine how exposure affects multiple metabolic pathways. These methods are ...
