Method Has anyone looked into NPK fertilizers?

[_Gollum_]

I saw these blue packets of NPK fertilizer at the plant store today and it occurred to me that they looked an awful lot like SN. Upon further research it seems like they can indeed kill in high enough doses through the same mechanism as SN (methaemoglobinaemia) and there are some case studies of intentional poisoning with them (example). The symptoms don't sound too unbearable either:

• < 10% - None (patients with underlying diseases may have more symptoms at lower level)
• 10-20% - Slight discoloration (eg, pale, gray, blue) of the skin
• 20-30% - Anxiety, headache, tachycardia, lightheadedness
• 30-50% - Dyspnea, weakness, confusion, chest pain
• 50-70% - Arrhythmias; altered mental status, delirium, seizures, coma; profound acidosis
• > 70% - Usually, death

Has anyone done a more thorough deep-dive into this? My biggest concern would be about dosage and administration.

I'm not sure about fertilizer. Farmers are known for using pesticides to ctb and just ctb'ing in general. If you have a local university library or even a public library you would have access to a lot more studies. It's a huge global problem so the "doing research" excuse would probably work very well.
