Table 1 shows the hydrocarbon quantities given as the mean nanograms per fly of each compound or mixture from the two peaks of interest.
Serotonin values are expressed in units of nanograms per milliliter.
This value is in picograms per milliliter; all others are in nanograms per milliliter.
To convert from micrograms to nanograms of endotoxin per gram fresh weight, each value was multiplied by the dilution factor (r100 or, occasionally, r500) and subsequently divided by 1000.
He says that the dioxin release is extremely low—he gives the figure in nanograms, which most of us would not understand.
These can be converted into nanograms per cubic metre by multiplying by 1000.
The maximum tolerable concentration of dioxins in milk is 0·7 nanograms per kilogram of milk.
This could seriously endanger the health of small children, as even a thousandth of a nanogram can cause symptoms, such as influenza, in adults if it enters the bloodstream.
