The main smell after organophosphorus pesticide poisoning is garlic, because after organophosphorus pesticides enter the body, these substances, in addition to combining with acetylcholinesterase inside the tissue, so that cholinesterase inactivation, but also into the blood circulation caused by an abnormal increase in the composition of the blood inside. If the process of entering the liver, through the metabolism and decomposition of the liver, so that organophosphorus pesticides gradually produced another toxic substance, which is the final metabolite. The metabolic substances are filtered through the blood circulation kidneys thus excreted from the urine, the taste is similar to the taste of garlic, but if a large amount of garlic is consumed for a long time, it will also be this taste. The two need to identify each other to see whether it is caused by poisoning or other causes, which can be determined by testing the organophosphorus composition inside the blood and conducting toxicological analysis.
