Fascinating post Oliver and I think you are right that we should be a bit more skeptical about ammonia than methane. Next weeks COSPAR meeting may say something though I am told it will not be completely up to date. It would be very good to see some hard data. What next? Benzene? Formaldehyde has been rumoured.

Hi David,

it would be very interessting to know what (if anything) exactly Mr. Formisano said about ammonia on Mars. There's a statement by ESA PR that there's no search for ammonia going on via the PFS. Thanks.

Please go to http://www.cosis.net/abstracts/COSPAR04/01554/COSPAR04-A-01554.pdf to read V. Formisano's 35 COSPAR July,2004 Paris Conference abstract on Mars Ammonia.

Thank you, Rick, for this info. Seems that we'll hear some interessting news from Paris in the next days...

Regarding Mars ammonia, JPL planetary atmospheres researcher Mark Allen stated in Oct.,2001, "At present there are no known abiotic processes that would result in ammonia being present in the atmosphere without the existence of life."

Thanks for sharing Brian and putnitg together this blog. Its also important to note that there are other things that can trigger the need to submit a corrected/revised RMP to the USEPA. A revised RMP must be submitted within the following time period for the following reasons1. Within 6 months of a change that alters the Program level of a process2. Within 6 months of a change that requires a revised offsite consequence analysis3. Within 6 months of a change that requires a revised PHA4. No later than the date on which a regulated substance is first present above a threshold quantity in a new process5. No later than the date on which a new regulated substance is first present in an already covered process above a threshold quantity6. No later than 3 years after a newly regulated substance is first listed by the USEPA7. Within 6 months of new accident history data becoming available8. Within 1 month of a change in emergency contact informationI've found that #8 is especially important to keep in mind because people change jobs often and it is not always the first thing on the mind of the new emergency contact to update the RMP.


yes, yes yes! I'm so happy you asked!I found all of my cleaning repecis on care2.com. I have asthma too.I gave you the link, but it's under Healthy Home and Non-Toxic Cleaning. Just use the search box to type in windows or floors or whatever you're seeking. It's a great site!Also, I own this book (2nd link) from Seventh Generation called The Green Guide, and made a lot o great cleaning repecis from it too. Try and see if you could buy it or take it out from your library.For my good friend's wedding I made her a beautiful book of all natural cleaning solutions, recipe style, from these sources. She loved it and now has a non-toxic home to raise her baby in. Also you can spend a lot more and go to Whole Foods/a natural store and buy scent free all natural products.Many good wishes
