Just an interesting tid bit of information.....This (stinky smell) is most likely low concentrations of H2S gas. Hydrogen Sulfied is a deadly gas (smells like rotten eggs to me) cause by the decomposition of organic matter in a low oxygen environment.
This information excerpted from the American National Standards Institute standard: Z37.2-1972 Acceptable Concentrations of Hydrogen Sulfide.

"Hydrogen Sulfide is an extremely toxic and irritating gas. Free hydrogen sulfide in the blood reduces its oxygen-carrying capacity, thereby depressing the nervous system. Hydrogen sulfide is oxidized quite rapidly to sulfates in the body, therefore no permanent aftereffects occur in cases of recovery from acute exposures unless oxygen deprivation of the nervous system is prolonged. There is no evidence that repeated exposures to hydrogen sulfide result in accumulative or systemic poisoning. Effects such as eye irritation, respiratory tract irritation, slow pulse rate, lassitude, digestive disturbances, and cold sweats may occur but these symptoms disappear in a relatively short time after removal from the exposure."

Odors become detectable in concentrations as low as .008 parts per million (ppm)
(California studies) but the sense of smell is lost after 2-15 minutes at 100 ppm.
After you lose your sense of smell it is too late and as we are found of saying here in the oild fiel of the Texas/ Louisianna gulf coast, "you are gone pecan" as in you die.
I can see the headlines "DEATH BY BONSAI" lol
