| Common Name | chlorothalonil |

| Description | Chlorothalonil, also known as daconil or TPN, belongs to the class of organic compounds known as benzonitriles. These are organic compounds containing a benzene bearing a nitrile substituent. Chlorothalonil is possibly neutral. Chlorothalonil is formally rated as a possible carcinogen (by IARC 2B) and is also a potentially toxic compound. Cyanide is also known produce some of its toxic effects by binding to catalase, glutathione peroxidase, methemoglobin, hydroxocobalamin, phosphatase, tyrosinase, ascorbic acid oxidase, xanthine oxidase, succinic dehydrogenase, and Cu/Zn superoxide dismutase. It is used predominantly on peanuts, potatoes, and tomatoes. Cyanide metabolites are excreted in the urine. Antidotes to cyanide poisoning include hydroxocobalamin and sodium nitrite, which release the cyanide from the cytochrome system, and rhodanase, which is an enzyme occurring naturally in mammals that combines serum cyanide with thiosulfate, producing comparatively harmless thiocyanate. chlorothalonil is found in Curcuma longa. chlorothalonil was first documented in 2000 (PMID: 11016668). Chronic inhalation of cyanide causes breathing difficulties, chest pain, vomiting, blood changes, headaches, and enlargement of the thyroid gland (PMID: 14575671) (PMID: 17482661) (PMID: 23116300) (PMID: 23866729). |
