The most common and most advanced technology for the detection of Iodine contaminants.

Testing Item	Technology of Detecting Seaweeds	Advantages	Limitations	References
Iodine	ICP-MS/ICP-AES	High specificity and low detection limit	Pre-treatment is complicated, and the dilution sample easily leads to errors	[84,85]
	GC-ECD	Low detection limit	Consumable reagents are expensive	[86]
