%PDF-1.6 %���� The combined effects of propiconazole and suspended sediment are dependent on concentrations of sediment and propiconazole. Liver adenomas have been observed in female mice. It is used to protect many crops, ornamentals, and turf; and as a preservative for wood and many other materials. It is a broad spectrum, non-systemic fungicide used very widely on peanuts and potatoes, as well as in many other applications. Do not contaminate water when disposing of equipment washwater. Triadimenol is triazole, and triadimefon is closely related chemically to triadimenol, with increasing toxicity for increasing isomer A ratios (isomer B is less toxic). Propiconazole has been reported to be stable in both aqueous and soil environments. In another example, Triclosan, which is used as in-can preservative (e.g., cosmetics), as a disinfectant, and in the treatment … Label elements: Pictogram: GHS07 exclam exclam Metalaxyl-M is a severe ocular irritant, but otherwise is toxicologically equivalent to metalaxyl. Mancozeb is a polymerized mixture of zinc and manganese salts of the organic molecule. Ce produit renferme un distillat de pétrole qui est de modérément à fortement toxique pour les organismes aquatiques. In this study, both individual and combined effects of propiconazole and runoff sediment on the aquatic model bryophyte Vesicularia dubyana are studied. The acute toxicity of prothioconazole is low, the oral LD50 being > 6200 mg/kg bw in rats. The rat oral LD50 of thiophanate-methyl is > 5000 mg/kg. The effects were investigated of the ergosterol-inhibiting fungicide, propiconazole, on mixed natural populations of bacterivorous and fungivorous flagellates in soil and on single species of bacterivorous flagellates in liquid culture. endstream endobj 258 0 obj <>stream Triadimenol is nonirritating, whereas technical-grade triadimefon is sensitizing. May cause sensitization by skin contact. Ne pas contaminer ces systèmes par application directe ou, encore, en … Propiconazole is not a mutagen, teratogen, or reproductive toxicant. Therefore, it reacts with fungal glutathione and disrupts numerous enzymatic cell processes. The compound causes reduction in BW, liver toxicity, and adverse changes in erythrocytes (rat) and the stomach (dog). H410: Very toxic to aquatic life with long lasting effects. propiconazole considered is, on the basis of information currently available, of toxicological or environmental concern. Propiconazole partitions from water to soil or sediment quickly, and is persistent under anaerobic conditions. Eco-chronic toxicity: N/A. Therefore, exposure of aquatic organisms to these low mobility pesticides, in many cases, will coincide with a high sediment concentration. ECOTOXICITY DATA: Data presented below is on the propiconazole technical product. When ETU was fed to rats for 2 years, it produced dose-related thyroid follicular hyperplasia at ≥ 50 ppm and malignant thyroid neoplasia at ≥ 250 ppm. 2.2 Short summary of the scientific justification for the CLH proposal Propiconazole is being evaluated as an existing active substance by Finland in both the AIR-3 . Triazoles (conazoles or imidazoles) include several excellent systemic fungicides, such as triadimefon (Bayleton), triadimenol (Baytan), bitertanol (Baycor), difenoconazole (Divident, Score), fenbuconazole or butrizol (Indar or Enable), propiconazole (Tilt, Orbic, Banner, Alamo), etaconazole or cyprodinil (Vangard), myclobutanil (Rally, Immunox, SpectracidePro, Nova, Eagle, Systhane), cyproconazole (Sentinel), and tebuconazole (Elite, Folicure, Raxil, Lynx). It’s less mobile in soil, and a relatively low toxicant to birds and bees. The potential of this fungicide to induce toxicity has not been fully explored. Developmental toxicity indicates increased ovary and testes weights, increased supernumerary lumbar ribs with triadimenol, and increased scapula malformations at maternal toxic doses in rabbits after triadimefon administration. H400: Very toxic to aquatic life. Chlorothalonil is the third highest production volume fungicide after sulfur and copper formulations. 2.2 Short summary of the scientific justification for the CLH proposal Propiconazole is being evaluated as an existing active substance by Finland in both the AIR-3 . Dermal contact with propiconazole can result in skin sensitization and irritation, though this effect has been observed in larger doses. At this dose, there were no deaths and clinical signs were limited to decreased motility and diarrhoea 1–6 h after dosing. The combined effects of propiconazole and suspended sediment are dependent on concentrations of sediment and propiconazole. proposal was withdrawn in 2011 as a result of receiving new data on aquatic toxicity. Propiconazole is a triazole fungicide that has been widely used in agriculture and has been detected in the aquatic environment. List of chemicals in the same family, including breakdown products, salts, esters, isomers, and other derivatives. Propiconazole partitions from water to soil or sediment quickly, where it is expected to be persistent under anaerobic conditions. Altered hepatocellular foci and hepatocellular tumors were increased in CD mice (but not in rats) fed the material for 2 years. Both are threshold effects that are judged by the US EPA to indicate a negligible cancer risk for humans. Occupational exposure to propiconazole may occur through dermal contact with this compound at workplaces where … Repeated high-dose exposure of rodents causes hepatocyte hypertrophy and necrosis. The other symptoms of toxicity include liver toxicity and CNS effects (general restlessness, alternating phases of increased and reduced motility, and aggressive behavior). The conazole class of fungicides includes cyproconazole, diniconazole, triadimefon, triadimenol, propiconazole, imazalil, etc. CONTACT : IUPAC HOME: AERU HOME: PPDB HOME: BPDB HOME: VSDB HOME: Top: Environmental Fate: Ecotoxicology: Human Health : Translations: Home: A to Z: Search: Support information: Purchasing and licensing: Propiconazole (Ref: CGA 64250) Last updated: 21/10/2020 … For example, permethrin used as insecticide and propiconazole used as wood preservative are very toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment, are harmful by inhalation, are harmful if swallowed, and may cause sensitization by skin contact. Thiophanate-methyl is a methyl-benzimidazole carbamate, a class of fungicides that disrupts fungal mitosis by interfering with β-tubulin assembly. Both are non-irritating and non-sensitizing for skin. Rats are especially sensitive to altered thyroid homeostasis with resultant formation of thyroid neoplasms due to their lack of thyroid-binding globulin (see Endocrine System, Chapter 58). It appears to phototransform slowly and is stable during hydrolysis. For example, permethrin used as insecticide and propiconazole used as wood preservative are very toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment, are harmful by inhalation, are harmful if swallowed, and may cause sensitization by skin contact. Chronic aquatic toxicity (Category 1) Classification according to EU Directives 67/548/EEC or 1999/45/EC Harmful if swallowed. ETU can be generated when produce treated with EBDC is stored or cooked, although at minute levels well below the US EPA’s level of concern. Acute aquatic toxicity (Category 1) Chronic aquatic toxicity (Category 1) Classification according to EU Directives 67/548/EEC or 1999/45/EC Harmful if swallowed. Fish Toxicity: Rainbow trout: 96-hour LC 50 = 850 ppb Fathead minnow: Early life stage chronic study NOAEC = 95 ppb Aquatic Invertebrate Toxicity: Daphnia magna: 96 -hour LC 50 = 4800 ppb ��f�~ ����K�[ ��u�iM=�3������m�z'����#�5{��=��~���Ӷ{μ����|q]�Z��]��)�R��{���p>�ų�(B�&$�,�]�1�y�_k�E���k��B�>) This agent has antibacterial and antiviral qualities as well. Their high toxicity is synergized when co-occurring with azole fungicides in the aquatic environment. List of chemicals in the same family, including breakdown products, salts, esters, isomers, and other derivatives. Acute Toxicity: Oral, Category 4 Skin Sensitization, Category 1 Aquatic Toxicity (Acute), Category 1 Aquatic Toxicity (Chronic), Category 1 2.1 Classification of the Substance or Mixture: H302: Harmful if swallowed. A total of 39% of foods tested were found to contain four pyrethroids, four herbicides, four fungicides, and six carbamates in different food samples. Hepatic enzyme induction produced secondary effects on the thyroid, probably attributable to increased thyroid hormone catabolism. Approved: 9 June 2017. The rodent oral LD50 for propiconazole ranges from 1211 to 2233 mg/kg, depending on the animal species and the chemical isomer. Little is known about the importance of synergy, when pyrethroids only occur during a short pulse of a few hours, as it is likely to happen in the environment, nor about the persistence of synergy over time. In rodent carcinogenicity studies at high doses, it has caused tumors in several organs. Propiconazole can enter the aquatic environment through spray drift and runoff. Very toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment. The fungicide affected a mixed natural population of fungivorous flagellates less than the population of bacterivorous flagellates. In the aquatic environment, propiconazole is presented to be moderately persistent to persistent. Abstract. In rodent renal proximal tubule epithelium, evidence suggests that cytotoxic thiol metabolites of chlorothalonil interfere with mitochondrial function, cause vacuolation and degeneration, and increase cell turnover, which eventually leads to epithelial hyperplasia and, eventually, a small increase in renal cortical adenomas and carcinomas.
