Normal and Toxic Levels of Aluminum in Blood Serum

Some variations of the chemtrail theory suggest that aluminum is part of what is being sprayed. The suggestions as to why this is so range from weather control, to geoengineering, to gaining control of the food supply with aluminum resistent crops. Some people have had thier blood tested for aluminum, and suggest that the presence of aluminum, sometimes at elevated levels, is evidence of the chemtrail theory.

The most obvious problems with this is that there's no way of knowing where the aluminum is coming from, and the wide variations in levels found indicate it's not comping from spraying, which would create a more even elevation in levels (if at all, seeing as it would take millions of tons to outweigh the environmental aluminum).

But those objections aside, what is the a "normal" level of aluminum? What would be considered toxic? Well it turns out it depends on how you measure it, and who you ask. More recent sources tend to use lower values. But it seems like below about 10 mcg/L is fairly normal, and above 50 mcg/L is generally now considered a toxic level.

(Note on units, 1 mcg/L = 1 µg/L = 1 ng/mL = 0.001 mg/L = 27 umol/L, I'll convert everything to mcg/L, micrograms per liter)
Reference Range: 0-6 mcg/L
Dialysis patients: <60 mcg/L

The reference range of Al in the blood of healthy individuals is generally considered to be below 10 mcg/L
Earlier, 100 mcg/L of considered to be a reasonable "limit" below which Aluminum neurotoxicity was not likely to occur. However since the late 1980's [health problems have been found] down to 50 mcg/L

Reference Interval: 0-15 mcg/L
Serum aluminum greater than 50 µg/L is consistent with overload and may correlate with toxicity.*

Reference Values:
0-6 mcg/L (all ages)
<60 mcg/L (dialysis patients-all ages)
Patients who had serum aluminum >60 mcg/L and <100 mcg/L were identified as candidates for later onset of aluminum overload disease that required aggressive efforts to reduce their daily aluminum exposure.

For laboratories using the atomic absorption spectrometry method, aluminum reference ranges varied from <5.41 μg/L to <20 μg/L (serum), <7.00 μg/L to 0 to 10 μg/L (plasma) and 5 to 30 μg/L (urine). For those using the inductively coupled plasma mass spectroscopy methodology, ranges varied from 0 to 6 μg/L to <42 μg/L (serum), 0 to 10 μg/L to 0 to 15 μg/L (plasma), and 0 to 7 μg/L to 5 to 30 μg/L (urine). None of the reference ranges are known to be derived from studies of healthy children, but relied instead on small studies of adult populations, adult dialysis patients, workers, or sick children on aluminum-containing parenteral therapy.

Serum levels in healthy individuals range from 1 to 3 mcg/L.

Aluminum is such a common element that contamination is very easy:

Failure to pay attention to proper specimen collection procedures can
cause abnormal results due to specimen contamination, which can lead
to misinterpretation and misdiagnosis:
● Special evacuated blood collection tubes are required for aluminum
testing. These tubes are readily available (Mayo Supply T184) and
should always be used.
● Most common evacuated blood collection devices used have
stoppers that are comprised of aluminum-silicate. Simple puncture of
the rubber stopper for blood collection is sufficient to contaminate the
specimen with aluminum. Typically, blood drawn in standard evacuated
blood tubes will be contaminated by 20 to 60 ng/mL aluminum.
● The use of wooden applicator sticks or pipette tips during specimen
aliquoting can cause abnormal results due to contamination.

Also diet can play quite a large factor, particularly the consumption of antacids, and the combination of antacids with citrus has a magnifying effect:

The first two columns above are interesting as they are the "control" of healthy individuals before the diet of antacids and citrus. They show a normal range of 2 to 11 mcg/L. But what's also interesting is the huger differences from week 1 to week 2 with no additions to the diet. Some levels stayed the same, some went from 11 to 2, one went from 3 to 11. This shows that aluminum levels in blood are highly variable, probably due to ordinary variations in diet and environmental exposure.
