It is practically nontoxic   dermaly, with a dermal LD50 of 20,000 mg/kg in rabbits [6,15]. The 4-hour   inhalation LC50 for metribuzin in rats is greater than 0.65 mg/L, indicating   moderate toxicity via the inhalation route [15]. Metribuzin has been shown   not to irritate the skin or eyes of rats, rabbits, guinea pigs, or human   volunteers. Effects of high acute exposure in metribuzin poisoned rats included narcosis (stupor) and labored breathing. Deaths occurred within 24 hours, and survivors recovered slowly without permanent effects. Organ toxicity In single high dose studies, metribuzin appears to depress the central nervous   system. Other studies indicate that the target organs of metribuzin are the   thyroid gland and the liver.
