Description

technical field

[0001] The invention relates to a test strip and a method for detecting dicofol, in particular to a colloidal gold test strip for detecting dicofol, which is particularly suitable for detecting dicofol residues in fruits. Background technique

[0002] Dicofol (dicofol) is an organochlorine acaricide, which can prevent and control mites on crops such as cotton, fruit trees, and vegetables. It has strong contact and stomach poisoning effects on adults, nymphs, and eggs. long term. Studies have shown that the drug has certain toxicity to humans and animals. The main symptoms of poisoning are headache, dizziness, sweating, chest tightness, mydriasis, blurred vision, nausea, vomiting, and diarrhea. Local exposure can cause contact dermatitis. Dicofol has been banned in my country, and the national standard GB2763-2019 "National Food Safety Standard Maximum Residue Limits of Pesticides in Food" also stipulates that the residue limit of dicofol in fruits is 1mg / kg....
