With regard to acrolein (uh-KRO-lee-in) and John B's e-mail below: 1) This laboratory webpage http://www.speclab.com/compound/c107028.htm lists five EPA methods for detecting acrolein, one being http://www.speclab.com/compound/m603.htm 2) This CDC webpage clearly describes another method: http://www.atsdr.cdc.gov/toxprofiles/tp124-c6.pdf An exerpt: 6.2 ENVIRONMENTAL SAMPLES Acrolein can be determined in air samples using NIOSH method 2501 (NIOSH 1984). In this method, a known volume of air is pumped through a tube containing a support coated with the derivatizing agent 2-(hydroxymethyl)piperidine. The derivative is eluted from the tube with toluene, and analyzed by GC using a nitrogen specific detector (NSD). Variations of this procedure have also been reported. Rietz (1985) used DNP as a derivatizing agent on the adsorbent tube, and made a final analysis using HPLC coupled to a UV detector. Acrolein has also been trapped for analysis by bubbling air through an aliquot of ethanol, adding methoxylamine hydrochloride to form a derivative, and then brominating the resulting adduct to allow increased detector sensitivity. Quantitation is achieved by GC using an electron capture detector (ECD) (Nishikawa et al. 1986). A summary of these techniques, along with methods for other environmental samples, are presented in Table 6-l. Interferences due to coincidental elution of derivatives of the compounds is a potential problem of these techniques.... 3) OSHA describes their Method 52 at http://www.osha.gov/dts/sltc/methods/organic/org052/org052.html There are pages upon pages of "acrolein detection" Google hits and you don't need to be an environmental scientist or industrial engineer to realize there are nasty compounds being emitted down here and that there are techniques available to detect them. While I can understand that there may be reasons why the "MPCA asked that these companies try to develop methods to improve detection limits for a chemical called acrolein," I can't understand why they haven't applied the methods already at their disposal. Meanwhile, we are left to ingest a "slimicide" and "military poison gas" while they dilly-dally. If there is difficulty collecting a sample at the point source, then they should pull their heads out of their stacks and collect some from the sidewalk - I can assure you there is plenty there to be collected. The same goes for the other compounds being emitted. There is absolutely no excuse for the inaction of the MPCA and other agencies. Thanks, Carlos, for your effort - a resounding "Boo!" to the 80 who care more about the Almighty Dollar than the health of my family and friends. Well, that was well worth $35. The check is in the mail. As for the Planetarium, I suggest they merge with the SMM and add $10 to my membership dues.

Which allows me once again to update the timeline for GSE on the website, and add a recent document from the MPCA. http://209.98.144.66/GSE/ I also have to add a comment on the document released by the MPCA along with an Office memorandum which is pretty lame to say the least. Apparently the MPCA feels that if they send us enough information (like the emissions report that is take from the MDH report) and say things they will fool us into thinking they are actually doing something. But you have to wonder when you read: "To fill in the data gaps and get a more complete picture of emissions, MPCA staff met with testing companies who have performed emission testing at ethanol production facilities including GSE. The MPCA asked that these companies TRY to develop methods to improve detection limit for a chemical called Acrolein. Acrolein is a pollutant that has proven difficult to quantify in ethanol stacks due to the high moisture content. Based on the response from the testing companies, additional emission tests will be planned." Well isn't that just pleasant, they are gonna plan for more emission tests. Despite the fact that they are already known to emit: Acetaldehyde, Acetic Acid, Acetone, Acrolein, BENSENE, Carbonyl Sulfide, Dimethyl Sulfide, Ethanol, Ethylbensene, Formaldehyde, Furfuraldehyde, Lactic Acid, MEK/butyrals, Methanol, Styrene, Tolualdehyde, Toluene. But they don't tell us how much they are emitting. Do some google searches and find out what these chemicals are. I think you will want to move right on down here and get in on the TOXIC environment. -- Sincerely, John Birrenbach W 7th Neighborhood, St Paul MN Political & Business Consulting ===Focusing on Internet Technologies=== http://www.birrenbach.com/ ===Web Hosting for Candidates and Issues=== http://209.98.144.66/ ===Harmony Cedar Quality Amish Products=== http://www.harmonycedar.com ====================================== "Six years on the council has trained me to feign interest for long periods of time" Chris Coleman Jan 21, 2004 _____________________________________________ NEW ADDRESS FOR LIST: [EMAIL PROTECTED] To subscribe, modify subscription, or get your password - visit: http://www.mnforum.org/mailman/listinfo/stpaul Archive Address: http://www.mnforum.org/mailman/private/stpaul/ _____________________________________________ NEW ADDRESS FOR LIST: [EMAIL PROTECTED] To subscribe, modify subscription, or get your password - visit: http://www.mnforum.org/mailman/listinfo/stpaul Archive Address: http://www.mnforum.org/mailman/private/stpaul/
