Like it says. The homes around have maybe have an attic fan or no ventilation. There is over 20ppm of Hydrogen Sulfide in the air and it keeps coming. How do I know? Because of the symptoms. I'm going to have to evacuate soon. I do not wish to contact all the viruses they are sending up along with the potential cancer causing agents.

What should I do to save my health, the pets health and clean the home air? (IMG:style_emoticons/default/ar15.gif)

By the way there are a lot of yougn children and babies who are home during this time besides the elderly.

The City just set me off. (IMG:style_emoticons/default/ar15.gif) (IMG:style_emoticons/default/ar15.gif)

How in the hell are they sending H2S into the homes? The only way I know of is through the sewer system and "P" traps should prevent that.

As I remember from my waste treatment days .. over 20 ppm is lethal.

We used to carry pennies in our pockets and if they discolored, we bailed.

In an enclosed space it would be lethal, but in the open the worst I got was the H2S sweats from over exposure.

Found it:

Hydrogen sulfide is regulated by OSHA and has a permissible exposure
limit of 20 parts per million (ppm) ceiling concentration and a peak exposure limit
of 50 (ppm) for no more than 10 minutes if no other measurable exposure
occurs.

Hydrogen sulfide can affect the body if it is inhaled or it comes in contact
with the eyes, skin, nose or throat. It can also affect the body if it is swallowed.
Inhalation of low concentrations may cause headache, dizziness and upset
stomach. At higher concentrations hydrogen sulfide may cause loss of
consciousness and death. Hydrogen sulfide has a strong odor of rotten eggs at
low concentrations and a sweetish odor at higher locations. Odor should not be
used as a warning of exposure since at concentrations of (20-30 parts per
million) hydrogen sulfide may deaden the sense of smell by paralyzing the
respiratory center of the brain and olfactory nerve.
There are two types of respiratory protection acceptable for protection
from hydrogen sulfide gas, SCBA or Supplied airline respirator. Respiratory
protection should only be used if engineering controls are not feasible to control
exposure to hydrogen sulfide gas.
There are may incidents of on the job fatalities caused by hydrogen sulfide
gas but with proper training, and monitoring equipment and safety and health
procedures for entering confined spaces, employees can work safely without
incident when encountering hydrogen sulfide gas at reservoirs and dams a
