Male and female ICR mice were given 0, 1875, 7500 or 30,000 ppm of chlorpropham (CIPC) in the diet for 13 weeks. Methemoglobin levels of male and female mice in the 7500 and 30,000 ppm groups were significantly elevated. Hemoglobin concentration, packed cell volume, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration and white blood cell count of male and female mice in the 30,000 ppm group were significantly increased. Dose-dependent splenomegaly was observed in male and female mice in the 7500 and 30,000 ppm group. Congestion, increased hemosiderin deposition and increased extramedullary hematopoiesis in the spleen, hematopoietic cell hyperplasia and hemosiderin deposition in bone marrow was observed dose dependently in male and female mice in the 7500 or 30,000 ppm group. Eosinophilic granular cytoplasm of hepatocytes, sinusoidal dilatation, hemosiderin deposition, extramedullary hematopoiesis and necrosis of hepatocytes were observed in the liver of male and female mice in the 30,000 ppm group. Hemosiderin deposition was increased in the kidney of male and female mice in the 30,000 ppm group. Administration of CIPC in diet for 13 weeks caused methemoglobinemia and splenomegaly in ICR mice.

Male F344 rats were given 0 or 3% chlorpropham in the diet and at 2, 4, 6, 8 or 13 weeks of administration, five rats in each group were examined for hematology, plasma clinical chemistry and pathology. Marked splenomegaly and hepatomegaly were observed in treated rats at 2-13 weeks of administration. Red blood cell counts, hemoglobin concentration, packed cell volume and platelet counts were significantly decreased and methemoglobin level, mean corpuscular volume and white blood cell counts were significantly increased in treated rats at 2-13 weeks of administration. The covalent binding of m-chloraniline m-CA, (the hydrolytic metabolite of chlorpropham) was observed in hemoglobin or splenic protein of treated rats, but only small amounts of free m-CA were present in blood or spleen. Congestion, hemosiderin deposits, extramedullary hemopoiesis and lymphoid atrophy in spleen and hyperplasia of hemopoietic cells in bone marrow were observed in treated rats at 2-13 weeks and fibrosis in splenic capsule were observed in treated rats at 4-13 weeks. The pathological changes in spleen rather than hematological changes progressed during administration, suggesting splenotoxicity of CIPC in rats.
