An extremely poisonous pesticide that should never have been made at all. TETS is short for tetramethylenedisulfotetramine,which has a peculiar "cage" chemical structure similar to some compounds found in camphor. TETS is odorless and tasteless and causes violent convulsions in all animals and humans. The pesticide is found in the People's Republic of China and has caused several cases of poisoning there, and sometimes finds its way here in the US, sold illegally by street vendors, where it has caused one fatal case of poisoning. One of the most insidious things about TETS is that it accumulates in the tissues of animals exposed to it and remains unchanged in the enviroment for years.
The Chinese authorities have reported several cases of poisoning from TETS.
