You don't need a MSDS for seawater skippy, simply a MSDS for NaCl and a percentage of NaCl in seawater. Certainly a person with your supposed credentials understands this.

There are two separate parts here: 1) Chemical NPK is no more harmful than table salt and 2) Do people swim in the ocean

You said that GD was wrong and that a couple of MSDS would reveal that he was wrong.

I pulled the MSDS and showed that GD was right that chemical ferts are less harmful than table salt. I assume that people swim in the ocean, but I haven't checked today.
You used LD50 values for urea alone. I wasn't aware urea comprises all N-P-K fertilizers available on the market. Odd, but since you insist let's pull some MSDS's of a very common compounds and fertilizers used.

Ammonium Sulfate

http://avogadro.chem.iastate.edu/MSD...H4%292SO4.html
CAS# 7783-20-2:
Oral, mouse: LD50 = 640 mg/kg;
Oral, mouse: LD50 = 4280 mg/kg;
Oral, rat: LD50 = 2840 mg/kg;
Oral, rat: LD50 = 4540 mg/kg;
Or how about an actual fertilizer, Urea Ammonium Sulfate.

Ammonium Thiosulfate Solution TFI Product Testing Program Results:
Acute oral toxicity, LD50: 1,950-2,890 mg/kg (rat, mouse)
Hmmm, looks like that is more toxic than NaCl.

How about Best Iron Supreme?

http://msds.simplot.com/datasheets/74368.pdf
Monoammonium Phosphate: > 2,000 mg/kg
Ammonium Sulfate: 640-4,250 mg/kg
Potassium Chloride: 1,500-2,600 mg/kg
Urea: 14,300 mg/kg
Again, odd. Three of the four listed ingredients are more toxic than NaCl.

How about Best NitreX

http://msds.simplot.com/datasheets/765512.pdf
Ammonium Nitrate: 2217 mg/kg
Monoammonium Phosphate: > 2,000 mg/kg
Ammonium Sulfate: 640-4,250 mg/kg
Potassium Sulfate: 6,600 mg/kg
Manganese Oxysulfate: 2150 mg/kg
Wow, even more odd. Four of the five ingredients are more toxic that NaCl.

Isn't that just damned inconvenient, heh skip? Shall we continue?

I never said I had a MSDS for seawater, did I skip? Perhaps you would care to show me where I did say that.
