Question
I want to discuss the sulfuryl fluoride problem. We take rice samples from a rice storage warehouse that has never been fumigated, because the rice is sold quickly.
After laboratory testing, it turned out that the rice contained sulfuryl fluoride.
Where does the sulfuryl fluoride come from?
Does it come from fertilizer residues in the field? Or from the residue of rice sacks?
Please colleagues who have ideas?
