NOEL Chronic administration of chlorothalonil has been associated with renal hyperplasia and hyperkeratosis of the forestomach in the kidney and forestomach of rats and male mice. These pre-neoplastic lesions precede subsequent tumour development in the rodent kidney and forestomach. The mode of action has been demonstrated to be epigenetic with a NOEL of 1.8 in rats and 1.6 in mice. In dogs, the pattern of toxicity is different from that in rodents with no evidence of toxicity in the kidney or forestomach, and a NOEL of at least 3 mg/kg b.w. (JMPR 1994). ADI (JMPR) 0.03 mg/kg [1994]; (EPA) 0.02 mg/kg (RED 1998). Toxicity class WHO (a.i.)
