1.) is 47.8 ng/L = 0.0478ppb?
and if so
would that above concentration be above
10,000 ug/L (what would this be in ppb)
2.) is 6.77 ng/m^3 = 0.0066 ppb?
an if so, would that exceed
0.5-5g/Kg for a 70 kg person (which is a lethal concentration) (and what would this be in ppb)
and would that exceed
Lethal concentration (50 percent kill): 2,485 mg/m3/4 hour... this is for a rat
3.) and finally what is
78.4 ng/g in ppb
and is it more then
Lethal dose (50 percent kill): 4 gm/kg (and what would this be in ppb)
parts per million (ppm) - this is sort of a generic unit of measure in the sense that it can represent a lot different units of measure (e.g. mg/L, ug/ml, mg/Kg, lb/acre), therefore a ppm equals one part of something per million parts of something else. So if you have water quality data in mg/L, that data is equivalent to ppm (i.e. 50mg Calcium/L = 50 mg Calcium/1,000,000 mg water/L = 50 ppm Calcium). By the way, if you have soil test data in parts per ...
The unit conversions for concentrations are analyzed.
An analytical chemist determines that an estuarine water sample contains 1.5 g/L of sulfate ion.
