What Are the Health Effects of Chronic Low-Level Hydrogen Sulfide?

There are substantial health effects from chronic exposure to low doses of hydrogen sulfide. In general, chronic exposure to this chemical is common in certain industrial enterprises, and, after a time, some have little awareness of the rather pungent smell of this chemical. In fact, reports are common of even small doses of the gas going unnoticed over time. This is a health effect in itself called olfactory fatigue or even paralysis. It is also found in sewers and occasionally known as "sewer gas" since it can be created by the rotting of waste products. In general, chronic exposure to this gas causes health problems, but none of lasting debilitating effect.

  1. Irritation

    • Likely, the most common effect of chronic exposure to this gas is regular irritation of the mucous membranes and the eyes. In many cases, even very low doses, taken chronically, of the gas can cause serious cases of conjunctivitis, or what some call "pink eye." This is the swelling of irritated eyelids leading to blurred vision and eye pain. In addition, the respiratory system can become irritated, and if untreated, can lead to bronchitis and headaches.

    Pharyngitis

    • Pharyngitis is potentially serious, but often passes of its own. This ailment is the swelling of the larynx in the back of the throat. If left untreated, it can, under certain circumstances, cause infection or even the blockage of the throat itself, but this is rare. In general, this condition leads to joint pain, fever and rashes. It can also lead to chronic wheezing if left untreated.

    Asthemia

    • This disease can be caused by low levels of hydrogen sulfide exposure over time. It is a general weakness of the body and limbs. In general this is a problem marked by weakness, lack of concentration and general ennui. It is a common side effect of the gas taken over time. It is advisable that those who show these symptoms while working for long periods of time in the petroleum, rubber or mining industries get checked out quickly.
