@karlauerbach @compoundchem Public health and solid waste people use the word “putresible” in regulatory language. Food, dead animals, and other waste that are capable of putrefaction (putrescible) must be disposed of weekly or twice-weekly with whatever else is defined as “garbage” locally to avoid odor and fly breeding. I didn’t know that there was any specific smelly chemical associated with the term. Non-putrescible solid wastes may be disposed of less frequently and are covered by many terms that may differ by locale—the #USPHS used to use “garbage” for any mixture of waste that included putrescibles, “rubbish” for non-putrescible waste, “municipal solid waste” for either from residential & commercial sources, “debris” for various kinds of inert wastes, and “refuse” or solid wastes for all of it. Flood wastes are a special case, since no matter what it started out as, it’s been contaminated by a mix of putrescible and toxic wastes of largely unknown types and concentration. #Helene #Cleanup

"Today’s news has been dominated by the terrible explosion in Beirut, Lebanon. The blame for the explosion has been directed at 3,000 tons of ammonium nitrate that was being stored in a warehouse in Beirut’s port. What is ammonium nitrate, why can it explode, and what happens when it does? This graphic takes a look."
