As others have stated... this is in nanograms. That is an incomprehensibly small amount - like a paperclip compared to a damned mountain.
On to the issue of whether or not sucralose is a "poison:"
www.elmhurst.edu...
Discovered in 1976, sucralose is 600 times sweeter than sugar and does not metabolize to produce energy, thus it does not contain calories. It is
the only low calorie sweetener that is made from sugar, which has been changed so passes through the body unchanged and unmetabolized. Substituting
for three alcohol groups on the sugar molecule with three chlorine atoms creates sucralose.

Results from over 100 animal and clinical studies included in this FDA approval process unanimously indicated a lack of risk associated with
sucralose intake. Acceptable human intakes across all populations have been pinpointed, as noted by Baird, Shephard, Merritt, and Hildick-Smith
(2000). The estimated daily intake (EDI) for humans is 1.1mg/kg/day. The intakes acceptable daily intake (ADI) is 16 mg/kg/day. The highest no adverse
effects limit (HNEL) is 1500 mg/kg/day (Baird et al., 2000).
Sucralose administration to Sprague-Dawley and COBS CD (SD) BR rats, mice, beagle dogs, monkeys, and eventually humans showed no signs of
toxicity, carcinogenicity, or other side effects. Studies ranged from single dose administration to eating trials of over two years. Common methods of
administration included oral, gavage, and IV intakes. No adverse reactions were observed at intakes up to 16,000 mg/kg/day in mice or 10,000 mg/kg/day
in rats—a dosage equivalent to 1,000 pounds of sucrose administered in a single day to a 165-pound adult (Goldsmith, 2000).
16 grams per kilogram of body weight. Most people are over 50 kilograms - closer to 70 and 80. That's -at least- a DAILY consumption of 800 -grams-
(about two pounds) to 1.28 kilograms (about three pounds). For two years.
All that said - I avoid artificial sweeteners. I am not afraid they are poisonous - but I am a supertaster (
science.howstuffworks.com... ) - artificial sweeteners have a very dry or side-sour taste to them that
is simply undesirable.
Sure - it has its advantages. I am excellent at reverse-engineering sauces... but I have a very narrow selection of alcoholic beverages I can
tolerate with friends (usually, I just stick to soda, tea, or whatever - I don't get too much crap for it, as I am usually the DD and thus enable
continued festivities.
Anyway - I avoid the stuff because it just doesn't taste like sugar. Sugar has a much more soft and 'calcified' (limey?) taste to it when eaten
raw. I will admit that splenda is pretty close to sugar... but it just has that off flavor (I suspect the chlorine substitution triggers additional
taste receptors that register it as having a 'sour' side-flavor and also trigger the 'dry' sensation - which feels similar, to me, to the 'dry'
flavor heavily chlorinated water has).
I agree - I don't see how people can drink it... but I am not concerned about it being a poison of some kind.
