(Citing separate studies...) "This neutralizing property of ClO2, combined with its ability to completely disinfect, makes DIOXIDERM and DIOXIGUARD ideal wound medications. Unlike iodine compounds, healing is not impeded. Veterinarians have been treating deep wounds and abscesses on tigers and elephants as well as dogs and cats with outstanding success. DIOXIDERM GEL had similar striking results on human (otherwise non-healing) diabetic ulcers." "Rats and honeybees were fed ClO2 in high doses over a two year period. No ill effects were noted" " With prolonged feeding toxicity is produced mainly in the red blood cell. Rats fed up to 1000 mg/l chronically for 6 months showed no significant hematological changes. After 9 months, however, red blood cell counts, hematacrit and hemoglobin were decreased in all treatment groups. " "At high ClO2 ppm, the method of rapid bacterial and viral kill appears to be the softening and
destroying of the cell wall or viral envelope.53 Human cells do not have cell walls and are
apparently unaffected. Our skin and bodies are likely protected from the general oxidative
effects of ClO2 by the many reducing agents in our cells and blood such as catalase, glutathione,
superoxide dismutase, vitamins E, C, A, B complex, uric acid, zinc and selenium. " "100 ppm 70,71,72, about the concentration of Frontier's DioxiDerm gel for topical us"

The kinetics of chlorite and chlorate in rats - PubMed
Chlorine dioxide (ClO2) is under consideration as an alternative to chlorination as a disinfectant for public water supplies. The primary products resulting from ClO2 disinfection of surface waters are chlorite (ClO2-) and chlorates (ClO3-). The kinetics of 36ClO2- and 36ClO3- was studied in rats. R …

Toxicity of Chlorine Dioxide in Drinking Water - M. S. Abdel-Rahman, D. Couri, R. J. Bull, 1984
Studies were conducted to determine the toxicity of CIO2 (0, 1, 10, 100, 1000 mg/L) and its metabolites, CIO-2 and CIO-3 (10, 100 mg/L) in drinking water in rats. After 9 months treatment the osmotic fragility of the red blood cells was decreased in all treatment groups, while a decreased blood glutathione was only observed in the metabolite groups. At 2, 4, and 6 months no significant hematologic changes were noted in treated rats compared to control. However, after 9 months RBC counts, hematocrit, and hemoglobin were decreased in all treatment groups. CIO2, CIO-2, and CIO-3 administered chronically in drinking water for 3 months inhibited the incorporation of 3H-thymidine into nuclei of rat testes. This inhibition was observed in the liver of CIO-2 groups and in the kidney of 100 mg/L CIO2 treatment. The incorporation in small intestinal nuclei was increased in both 10 and 100 mg/L CIO2 and in 10 mg/L CIO-2. The treatment with CI compounds decreased rat body weight in all groups after 10 and 11 months treatment.

Sodium chlorite increases production of reactive oxygen species that impair the antioxidant system and cause morphological changes in human erythrocytes - Ali - 2017 - Environmental Toxicology - Wiley Online Library
"NaClO2 induces oxidative stress in human erythrocytes, damages the membrane, and impairs the cellular antioxidant defence system. This oxidative damage can shorten the life span of erythrocytes in blood resulting in red cell senescence."
Oxidative damage to the erythrocyte induced by sodium chlorite, in vivo - PubMed
"Sodium chlorite in drinking water was found to produce a slight but compensated anemia in rats after exposure to up to 500 ppm for 90 days. Decreases in hemoglobin, red cell count, and packed cell volume seen after 30 days exposure had substantially recovered by 90 days of treatment. Signs of adaptation remained in that 2,3-diphosphoglyceric acid concentrations in the red cell remained elevated after 90 days exposure to 50 and 100 ppm CIO2-. However, dose-related decreases in erythrocyte glutathione levels, detected at chlorite levels as low as 50 ppm, remained decreased after 90 days exposure. While no other signs of overt toxicity were observed, the fact that hemolytic anemia was involved was confirmed by an increased turnover of red cells in cats exposed to CIO2-. Chlorite-induced decreases in glutathione in vivo were demonstrated to enhance formation of hydrogen peroxide when treated further with chlorite in vitro."
[Bleaching agent poisoning with sodium chlorite. The toxicology and clinical course] - PubMed
"Preparation of the bleaching solutions was associated with a sharp pungent smell, coughing, pharyngeal irritation and headache. Seven hours later increasing cough and dyspnoea led to hospitalisation. Clinical findings were tachypnoea, tachycardia, and rales of auscultation; clinical chemistry revealed marked leucocytosis. Chest X-ray did not yield any abnormal findings. Initially the vital capacity and forced expiratory volume in 1 s markedly reduced and the resistance correspondingly enhanced. Blood gas analysis showed hypoxaemia despite alveolar hyperventilation. Administration of corticosteroids resulted in significant alleviation of complaints and in improved lung function with stabilisation in a highly normal range, as confirmed by follow-up examination two years later."
"The chlorine dioxide intoxication had been due to pH level reduction resulting from an incorrect proportioning and handling of the individual bleaching agent components when preparing the solution."

Evasive Behavior of the Red Flour Beetle, Tribolium castaneum, against Chlorine Dioxide and Its Suppression by Heat Treatment | Korea Science
"Chlorine dioxide treatment even at 400 ppm for 6 h did not kill any T. castaneum. However, the combined treatment of chlorine dioxide with the heat treatment for 6 h resulted in 95% mortality. These results indicated that heat treatment suppressed the evasive behavior of T. castaneum and synergized the control efficacy of the chlorine dioxide fumigant. "

ISOPROPYL ALCOHOL -Exposure Limits for Airborne Contaminants
[Old - 1984?] Isopropyl alcohol is manufactured in the United States by an indirect hydration technique in which a fraction containing 40-60% propylene that is isolated from refinery exhaust gases reacts with sulfuric acid (Lowenheim and Moran, 1975). In an older (strong-acid) process, 88-93% sulfuric acid reacted with propylene gas at 25-60°C for a long time. In a newer (weak-acid) process, which has replaced the strong-acid process, propylene gas is absorbed in 60% sulfuric acid at 85°C for a short reaction time (NIOSH, 1976). Estimated annual production capacity for 1981 was 2.8 million pounds (SRI, I...
