3. Study articles on

a) the t-butyl mercaptan release in Alabama (Behbod 2014)

b) a 1984 pulp worker study where the workers were exposed to both hydrogen sulfide and methyl mercaptan (Kangas 1984) at levels 2000 – 3000-times the levels potentially present at Porter Ranch, and the authors concluded “Regarding the results of the clinical survey, it seems that there are no glaring medical problems easily noted in an ordinary check-up”

c) a study of pets exposed to a propyl mercaptan release (Maciejewski 2008) where the authors stated “a systematic review of electronic medical records of dogs and cats exposed to release of propyl mercaptan showed no conclusive and consistent evidence of adverse health effects”.
