|Did that Dr. ever study chemistry?|
What is in your stomach after you eat beans and have a glass of milk?

|This the lab report. The study was based on urine samples-so this is the result after digestive processing.|

|How do you know the people didn't eat beans and drink milk? There is glycine in beans and milk has phosphates.|
The research has got to be from a peer reviewed scientific journal, and even then I question it, unless I know the researchers.
My chemistry is a little faded but -when I look at the low concentrations which they found----I think you would find that in any one who ate beans and drank milk. They did not specify what the residues were? It strikes me it is not great research. What makes me think it is sketchy research
is that they say "by an accepted method". In North America they would give the exact method such as ASTM ----number such.
ASTM stands for American Standards for Testing Materials. A good legitimate scientific report states exactly what they were doing.
It identifies the "accepted method".

| These are the analytical procedures that they used. They did not have a dietary history for the urine samples. They did however say that this was an initial result, suggesting that further investigation was warranted. So it is initial not conclusive research.|
3. Analytical procedures
The human urine samples were analyzed by means of a validated GC-MSMS
method. In addition we determined creatinine to correct for diurese, if needed.
Brief descriptions and the relevant specifications are listed below.
Analytical Method for Glyphosate and AMPA
1) Evaporation and dissolution of the residue in methanol,
2) derivatization using trifluoroethanol and trifluoroactic acid anhydride
Measurement: GC-MSMS, NCI mode
Capillary Column: HP-Innowax
Precision: 8% each
Recovery: 95% each
Linearity: 0,2 - 20 µg/L each
Limit of Quantitation (LOQ): 0,15 µg/L each

|There could be several validated GC-MSMS methods?|
I would have to delve way into the chem books to check their methodology.
Gardening now and not going to do chemistry on a nice day!

|Enjoy those nice days while you may! Its 90 degrees F and rain nearly every day here in Alabama. There is hardly an opportunity to even get out at cut back the poison ivy!|
