Hadley's other pet project is a system that breaks down hydrogen sulfide in sewer lines.
Hydrogen sulfide faces skepticism because of its mysterious nature and its potential for toxicity.
There are mini earthquakes, methane, benzene and hydrogen sulfide being released into the community.
In 2005 he put mice into hibernationlike states with small doses of the toxic gas hydrogen sulfide.
Roth is trying to figure out how hydrogen sulfide does what it does.
The highly toxic H2S (hydrogen sulfide) and CO2 (carbon dioxide) are removed along with excess water to get the gas below 7 ppm (parts per million).
He hit on hydrogen sulfide as a potential knockout after watching a television program in 2002 about spelunkers who had to wear respirators when exploring caves filled with the toxic gas.
It treats the wastewater more effectively, and doesn't have any of the environmental drawbacks of that technology, such as production of unwanted hydrogen sulfide or possible release of methane, a potent greenhouse gas.
When his staff gassed mice with hydrogen sulfide at a fraction of the lethal dose for humans, their body temperatures plunged, all movement stopped, and their breathing slowed to just a few breaths per minute.
When the Department of Environmental Protection noticed hydrogen sulfide in the city's water supply, Stephen Hollowell, general manager of Steinhatchee's chlorine-based water-treatment plant, and his board were willing to a take a chance on new technology.
In one Ikaria-funded study published in the Proceedings of the National Academy of Sciences, Albert Einstein College of Medicine's David Lefer found that low doses of hydrogen sulfide slashed heart damage by 72% in mice after heart attacks, even without inducing hibernation.
This liberates hydrogen ions for the acidity, turns insoluble sulfide into very soluble sulfate, and creates rust from reduced iron, a fascinating, if annoying, chemical process.
