Thats some funny stuff. I have worked around, been splashed with and inhailed JP-8 for the last 17 years, and I don't have an extra arm growing out of my head, or had anything negitive come back on a blood test. So just use your head folks, don't go to the coast if you're weak.

so while you are putting him down now you all betrayed your own level of understanding
the other epa chart was in PPM
here you go
you may wish to convert concentrations in micrograms per cubic meter (µg/m3) to concentrations in parts per million (ppm) or parts per billion (ppb).
This conversion can be achieved using the following equations:
Cppb = Cµg/m3 x 24.45/MW
Cppm = Cµg/m3 x 0.02445/MW
where
C = Concentration of the contaminant
MW = Molecular weight of contaminant
24.45 = Constant representing the volume, in liters, of one mole of a gas at standard temperature (25°C) and pressure (1 atmosphere).
For example:
100 µg/m3 of SO2, which has a molecular weight of 64, converted to ppm:
Cppm = 100 x 0.02445/64
totally different
williams stuff is all out there for free if you look
so to make sense of the EPAs figures you have to not be comparing apples amd oranges
here
you might need this to read the EPA chart
www.environment-agency.gov.uk...
has been set at 5 parts per billion (ppb) or 16.25 microgrammes per cubic metre (ug / m3). Benzene

Health Effects of Hydrogen Sulfide
H2S is classed as a chemical asphyxiant, similar to carbon monoxide and cyanide gases. It inhibits cellular respiration and uptake of oxygen, causing biochemical suffocation. Typical exposure symptoms include:
LOW
0 - 10 ppm Irritation of the eyes, nose and throat
MOD
10 - 50 ppm Headache
Dizziness
Nausea and vomiting
Coughing and breathing difficulty
High
50 - 200 ppm Severe respratory tract irritation
Eye irritation / acute conjunctivitis
Shock
Convulsions
Coma
Death in severe cases

1000 ppb = 1 ppm
100 ppb = 0.1 ppm
10 ppb = 0.01 ppm
1 ppb = 0.001 ppm
5ppm=5000 ppB
should I say say DuH here?
