Additional Information
RTECS: TH4375000
Cough, Shortness of breath, Headache, Nausea, Vomiting, Pulmonary edema. Effects may
be delayed., Hydrogen sulfide is strongly bound to methemoglobin in a manner similar to
cyanide. Toxicologically, its reaction with enzymes in the blood stream inhibits cell
respiration resulting in pulmonary paralysis, sudden collapse, and death. It is recognized by
its characteristic odor of "rotten eggs". The detectable, minimum perceptible odor occurs at
0.13ppm, rapid olfactory fatigue can occur at high concentrations (>100 ppm). At
concentrations of 20ppm hydrogen sulfide begins acting as an irritant on the mucous
membranes of the eyes and respiratory tract and increases with concentration and
exposure time. Eye irritation is characterized by irritation of the conjunctiva with
photophobia to keratoconjunctivitis and vesiculation of the cornea epithelium. Prolonged
exposure to moderate concentrations (250ppm) may cause pulmonary edema. At
concentrations over 500ppm, drowsiness, dizziness, excitement, headache, unstable gait,
and other systemic symptoms occur within a few minutes. Sudden loss of consciousness
without premonition, anxiety, or sense of struggle are characteristic of acute exposure at
concentrations above 700ppm. At concentrations of 1000-2000ppm hydrogen sulfide is
rapidly absorbed through the lung into the blood. In this range a single inhalation may
cause coma and may be rapidly fatal. Initially hyperpnea occurs, followed by rapid collapse
and respiratory inhibition. At higher concentrations, hydrogen sulfide exerts an immediate
paralyzing effect on the respiratory centers. When concentration reaches 5000ppm,
imminent death almost always results.

Phosphorus Bohr ModelSee more Phosphorus products. Phosphorus (atomic symbol: P, atomic number: 15) is a Block P, Group 15, Period 3 element. The number of electrons in each of Phosphorus's shells is 2, 8, 5 and its electronic configuration is [Ne] 3s2 3p3. The phosphorus atom has a radius of and its Van der Waals radius is Phosphorus is a highly-reactive non-metallic element (sometimes considered a metalloid) with two primary allotropes, white phosphorus and red phosphorus its black flaky appearance is similar to graphitic carbon. Compound forms of phosphorus include phosphates and phosphides. Phosphorous was first recognized as an element by Hennig Brand in 1669 its name (phosphorus mirabilis, or "bearer of light") was inspired from the brilliant glow emitted by its distillation.


See more Sulfur products. Sulfur (or Sulphur) (atomic symbol: S, atomic number: 16) is a Block P, Group 16, Period 3 element with an atomic radius of 32.066. Sulfur Bohr ModelThe number of electrons in each of Sulfur's shells is 2, 8, 6 and its electron configuration is [Ne] 3s2 3p4. In its elemental form, sulfur has a light yellow appearance. The sulfur atom has a covalent radius of 105 pm and a Van der Waals radius of 180 pm. In nature, sulfur can be found in hot springs, meteorites, volcanoes, and as galena, gypsum, and epsom salts. Sulfur has been known since ancient times but was not accepted as an element until 1777, when Antoine Lavoisier helped to convince the scientific community that it was an element and not a compound.
