Specification
Arsenic acid, lead salt (CAS NO.7645-25-2) is a kind of pesticide. It is high toxic. It will emission toxic compounds of arsenic and lead in smoke when heating. So the storage environment should be ventilate, low-temperature and dry. Keep Arsenic acid, lead salt (CAS NO.7645-25-2) separate from raw materials of food.
