This is the organizing page for research related to hydrogen sulfide in Public Lab. (above: DIY colorimetric strips reacting to H2S by @megan) What is hydrogen sulfide, what are its effects, and where is it found?Hydrogen sulfide, with the chemical formula H2S, is a flammable gas that has a pungent odor at low concentrations and is odorless at higher concentrations. It can be a respiratory irritant and a neurotoxin. Read more about hydrogen sulfide health effects. Hydrogen sulfide is naturally formed in low-oxygen conditions with sulfate present, such as in organic-rich sediments and thus in petrochemical source rocks. Upon exposure to oxygen, hydrogen sulfide readily oxidizes to sulfur dioxide or sulfate, and generally reacts within hours to days. Read more about hydrogen sulfide sources and spatial and temporal variation How are hydrogen sulfide emissions and exposures regulated?In the United States, hydrogen sulfide emissions are only federally regulated to the extent that they contribute to sulfur dioxide formation, and thus acid rain. These emissions are regulated through the Prevention of Significant Deterioration of major stationary sources review and permitting. Exposure to hydrogen sulfide is mostly regulated in terms of occupational exposure, with very few states regulating ambient exposure to this toxin. Read more about hydrogen sulfide regulations How can hydrogen sulfide be measured?While there is no federal regulatory method for hydrogen sulfide in the US, labs, agencies, and oilfield workers often measure hydrogen sulfide gas through several different means:
Do-It-Yourself approaches to detectionThere are three prototype, low-cost hydrogen sulfide detection methods currently being explored by Public Lab community members. These include:
QuestionsWe can't make progress on these techniques and resources without addressing our unknowns. Please ask questions to help shape the direction of our work!

What is hydrogen sulfide, what are its effects, and where is it found?Hydrogen sulfide, with the chemical formula H2S, is a flammable gas that has a pungent odor at low concentrations and is odorless at higher concentrations. It can be a respiratory irritant and a neurotoxin. For more information about hydrogen sulfide health effects, please see: https://publiclab.org/wiki/hydrogen-sulfide-effects. Hydrogen sulfide is naturally formed in low-oxygen conditions with sulfate present, such as in organic-rich sediments and thus in petrochemical source rocks. Upon exposure to oxygen, hydrogen sulfide readily oxidizes to sulfur dioxide or sulfate, and generally reacts within hours to days. For information about hydrogen sulfide sources and spatial and temporal variation, please see: https://publiclab.org/wiki/hydrogen-sulfide-environment How are hydrogen sulfide emissions and exposures regulated?In the United States, hydrogen sulfide emissions are only federally regulated to the extent that they contribute to sulfur dioxide formation, and thus acid rain. These emissions are regulated through the Prevention of Significant Deterioration of major stationary sources review and permitting. Exposure to hydrogen sulfide is mostly regulated in terms of occupational exposure, with very few states regulating ambient exposure to this toxin. For detailed information of environmental and occupational hydrogen sulfide regulations, please see: https://publiclab.org/wiki/hydrogen-sulfide-regulations How can hydrogen sulfide be measured?Hydrogen sulfide can be measured through a variety of means. While there is no federal regulatory method for hydrogen sulfide, agencies often measure hydrogen sulfide emissions through continuous sampling of gaseous emissions, and measure hydrogen sulfide workplace exposure through air grab samples chemically processed and discerned through gas chromatography. For routine monitoring, there are several hydrogen sulfide passive samplers that utilize color-changing oxidation-reduction reactions. For more information about laboratory, commercially available, and DIY hydrogen sulfide measurement methods, please see: https://publiclab.org/wiki/hydrogen-sulfide-detection There are three low-cost hydrogen sulfide detection methods currently being explored by Public Lab community members. These include a silver halide photo paper method, a copper rod method, and an anodic stripping voltammetry method.

A draft page for collecting and organizing information, questions, and projects related to hydrogen sulfide, also known as H2S.
Table of contentsFraming the problemWe are transferring these questions to the Questions system -- please copy them into a question
Where is this an issue?Here I've ( @warren ) collected some of the notes folks have posted on PublicLab.org about where H2S has been a problem, under the tag #h2s-sites : [notes:h2s-sites] Post more on H2S sites - help build out this list by posting your own notes on H2S-affected sites Detecting H2SWikipedia's article, which is pretty well referenced, shows that:
This seems to be well below what's cited as a risk to health, but OSHA warns not to use smell as a means to detect it (OSHA.gov):
Most info I've ( @warren ) compiled here shows 10+ parts per million as when health effects are of concern, but one cites a TWA (time weighted average) of 1ppm -- over 8 hours. See below in the health effects section. QuestionsSome questions about detecting hydrogen sulfide are below. We are transferring these questions to the Questions system -- please copy them into a question

(Exposure information from OSHA.gov) Exposure limits from various sources, from an Airgas Materials Safety Data Sheet: Note that these show toxicity at levels close to the ability of the wearable electronic monitors (see above) can detect -- 10-15ppm; "STEL" means Short Term Exposure Limit, or an "acceptable average exposure over a short period of time."
