Ossendorp (Centre for Substances and Integrated Risk Assessment, National Institute of Public Health and the Environment, The Netherlands) EXPLANATION Propiconazole was first evaluated by the JMPR in 1987 and has been reviewed in 1991 … 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. From: Encyclopedia of Toxicology (Third Edition), 2014, S.C. Gad, T. Pham, in Encyclopedia of Toxicology (Third Edition), 2014. Biotic or Aerobic Half-life (days) 90 2 High 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). 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. Pawan K. Gupta, in Reproductive and Developmental Toxicology (Second Edition), 2017. Mancozeb itself has not demonstrated carcinogenicity, teratogenicity, or reproductive toxicity, although chronic studies in rats and dogs showed inconsistent small effects on thyroid morphology and depressed iodine uptake. Acute Toxicity 4 (H302); Skin Sensitisation 1 (H317); Reproductive Toxicity 2 (H361d); Aquatic Acute 1 (H400, M-factor of 1) and Aquatic Chronic 1 (H410, M-factor of 1). Very toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment. The most recently published Federal Register notice on April 19, 2013 ( 78 FR 23497 ) (FRL-9381-8) cited an immunotoxicity study as a data gap, but since the publication of that final rule, the Agency has evaluated and granted a waiver request for this data requirement for the conazoles as a class based on the following considerations: Aquatic Toxicity (Acute), Category 1 Aquatic Toxicity (Chronic), Category 1 2.1 Classification of the Substance or Mixture: H302: Harmful if swallowed. worked on the enantiomeric separation of six triazole fungicides, namely, cyproconazole, Safety Assessment including Current and Emerging Issues in Toxicologic Pathology, Haschek and Rousseaux's Handbook of Toxicologic Pathology (Third Edition), TEOSINTE BRANCHED1/CYCLOIDEA/PROLIFERATING CELL FACTOR1, RELATED TO ABI3/VP1, ABA INSENSITIVE 3/VIVAPARIOUS 1, SOMATIC EMBRYOGENESIS RECEPTOR-like KINASE, Myeloblastosis family transcription factor-like 2, Leaf and tiller angle increased controller.

In longer-term studies, propiconazole acts as a phenobarbital-like liver enzyme inducer. The combined effects of propiconazole and suspended sediment are dependent on concentrations of sediment and propiconazole. This compound is a phenylamide that disrupts fungal RNA polymerase, and the R-enantiomer is much more active. We use cookies to help provide and enhance our service and tailor content and ads. 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 exposure (JMPR, 2004). Propiconazole has been reported to be stable to hydrolysis as well as aqueous and soil photolysis. They show long protective and curative activity against a broad spectrum of foliar, root, and seedling diseases such as leaf spots, blights, powdery mildews, rusts, smuts, and others caused by many ascomycetes, imperfect fungi, and basidiomycetes. Propiconazole (PCZ), a triazole fungicide, is widely present in the aquatic environment, but little is known regarding its chronic toxicity in the fish brain. Following long-term exposure, propiconazole causes liver hypertrophy and tumors in mice, uterine lumen dilation in rats, developmental toxicity indicative of reduced pup weight at parentally toxic doses, and skeletal variations in laboratory animals (JMPR, 2004). Triadimenol is triazole, and triadimefon is closely related chemically to triadimenol, with increasing toxicity for increasing isomer A ratios (isomer B is less toxic). The Risk Assessment Committee (RAC) of the European Chemicals Agency (ECHA) proposed classification of propiconazole for reproductive toxicity in category 1B leading to a critical area of concern concerning approval criteria and the relevance of groundwater metabolites. H400: Very toxic to aquatic life. A total of 39% of foods tested were found to contain four pyrethroids, four herbicides, four fungicides, and six carbamates in different food samples. The acute toxicity of prothioconazole is low, the oral LD50 being > 6200 mg/kg bw in rats. Propiconazole is a chiral fungicide used in agriculture for control of many fungal diseases on a variety of crops. Read it on the Wiley Online Library: Article | PDF.

This study helped to promote consumer safety by assaying pesticide residues in food items. Pawan K. Gupta, in Veterinary Toxicology (Third Edition), 2018. This study aimed to investigate the effects of propiconazole exposure on lipid metabolism in the early life stages of zebrafish for 120 h postfertilization (hpf). The conazole class of fungicides includes cyproconazole, diniconazole, triadimefon, triadimenol, propiconazole, and imazalil and has low to moderate acute toxicity. Following long-term exposure, liver hypertrophy and tumors (mice), uterine lumen dilation (rats), and developmental toxicity indicative of reduced pup weight at parenterally toxic dose and skeletal variations in laboratory animals have been observed (JMPR, 2004). First published in the EFSA Journal: 12 July 2017. In the aquatic environment, propiconazole is presented to be moderately persistent to persistent. 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. Altered hepatocellular foci and hepatocellular tumors were increased in CD mice (but not in rats) fed the material for 2 years. The following list of North American Industrial Classification System (NAICS) codes is not intended to be exhaustive, but rather provides a guide to help readers determine whether th… The conazole class of fungicides includes cyproconazole, diniconazole, triadimefon, triadimenol, propiconazole, imazalil, etc. and has low to moderate acute toxicity. For the purpose of this reregistration eligibility decision (RED), EPA has concluded that propiconazole does not share a common mechanism of toxicity with other substances. 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.

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. Metalaxyl is also negative for reproductive and developmental effects, and the great majority of genotoxicity tests have been negative. Propiconazole partitions from water to soil or sediment quickly, where it is expected to be persistent under anaerobic conditions. Propiconazole has been detected, but has a low detection frequency. Acute toxicity Terrestrial Toxicity Birds Oral LD50 mg/kg Chemical Name Propiconazole:>2510 Mallard duck, Bobwhite quail Bees Oral LD50 μg/bee Chemical Name Propiconazole:>100 12.2. Liver adenomas have been observed in female mice. Propiconazole can enter the aquatic environment through spray drift and runoff. Histopathological liver changes were not detected in the dogs despite increased liver weights as well as elevated serum alanine aminotransferase (ALT) and alkaline phosphatase (ALP) activities. Heyden, in Encyclopedia of Food and Health, 2016. Dermal contact with propiconazole can result in skin sensitization and irritation, though this effect has been observed in larger doses. propiconazole for reproductive toxicity in category 1B leading to a critical area of concern concerning approval criteria and the relevance of groundwater metabolites. You may be potentially affected by this action if you are an agricultural producer, food manufacturer, or pesticide manufacturer. Our findings therefore highlight the risk of reproductive toxicity in amphibians as a consequence of developmental exposure to azole pesticides and other aromatase inhibitors. The rat oral LD50 of thiophanate-methyl is > 5000 mg/kg. However, the triazole fungicides share common metabolites, the free triazole compounds 1,2,4-triazole, triazole 1 Triazole fungicides are a class of pesticides used indiscriminately in large amounts and pose a serious threat to the environment. Hepatocellular adenomas and rostral (anterior) pituitary lobe adenomas have also been reported in rodents treated with ETU, and it has caused reproductive and developmental abnormalities in rats, including major defects in fetal brain development, skeletal abnormalities, and cryptorchidism. 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. Benzalkonium chloride (used, e.g., as a disinfectant for personal hygiene and in the preparation of surfaces) is highly toxic to aquatic organisms, and harmful in contact with skin. Dogs dosed at 250 mg/kg/day for 2 years had increased thyroid weights. Propiconazole is known to contaminate water and can be highly toxic to fish, making it all the more important to avoid using this chemical within the vicinity of water sources. Persistence and degradability Water DT50 days Chemical Name Propiconazole:5.4 Soil DT50 days Chemical Name Hence, we consider the low propiconazole concentration, 33 μg/L, to be environmentally relevant for amphibian tadpole exposure to aromatase inhibitors in the aquatic environment. DISCLAIMER 1 FAO specifications are developed with the basic objective of … Therefore, it reacts with fungal glutathione and disrupts numerous enzymatic cell processes. Both are threshold effects that are judged by the US EPA to indicate a negligible cancer risk for humans.

Biocidal products can often contain substances of concern with allergic, ecotoxic, carcinogenic, developmental neurotoxic, or endocrine-disrupting properties. GEORGE N. AGRIOS, in Plant Pathology (Fifth Edition), 2005. The fungicide affected a mixed natural population of fungivorous flagellates less than the population of bacterivorous flagellates. 257 0 obj <>stream Avian toxicity: ( Propiconazole technical ) Practically non-toxic. 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. It is a broad spectrum, non-systemic fungicide used very widely on peanuts and potatoes, as well as in many other applications. An estimated BCF of 146 suggests the potential for bioconcentration in aquatic organisms is very high. The potential endocrine disruption of propiconazole was identified both as an issue that could not be finalised and a critical area of concern. It appears to phototransform slowly and is stable during hydrolysis. Metalaxyl-M is a severe ocular irritant, but otherwise is toxicologically equivalent to metalaxyl. Propiconazole is expected to take from 90 days to over 200 days to degrade to half of the applied concentration on land but less than a week in water. Metalaxyl-M is the R-enantiomer-enriched (97%) form of metalaxyl. This agent has antibacterial and antiviral qualities as well.

Propiconazole has been reported to be stable in both aqueous and soil environments. The rodent oral LD50 for propiconazole ranges from 1211 to 2233 mg/kg, depending on the animal species and the chemical isomer. Type: Reasoned Opinion. It inhibits the formation of critical fungal cell membrane ergosterols, primarily by blocking the action of 14-α-sterol demethylase, the only cytochrome common to animals, plants, fungi, and prokaryotes. " _##��������{��� propiconazole considered is, on the basis of information currently available, of toxicological or environmental concern. Ecotoxicity: ( Propiconazole technical ) Fish - Acute 96 hour LC50 (mg/l): 12.15 mg/l for rainbow trout Toxicity to daphnia and other aquatic invertebrates EC50: 42.85 mg/l for daphnia magna (48 hr). In rodent carcinogenicity studies at high doses, it has caused tumors in several organs. A study on five conazoles, namely, epoxiconazole, ketoconazole, prochloraz, propiconazole, and tebuconazole, indicates that all these conazoles can be classified as weakly embryotoxic (Dreisig et al., 2013). The compound causes reduction in BW, liver toxicity, and adverse changes in erythrocytes (rat) and the stomach (dog). It is therefore vital to monitor, identify, and quantify pesticide levels in food samples. Propiconazole has a log Kow of 3.65 and the bioconcentration factors (BCFs) range from 24 to 516 times in fish tissues.

At low sediment concentration (e.g., 100 mg/L), neither S1 nor S2 reduce the toxicity of propiconazole, as only 2% of propiconazole are bound to particles. The conazole class of fungicides includes cyproconazole, diniconazole, triadimefon, triadimenol, Hormone Metabolism and Signaling in Plants, Chromatography: Supercritical Fluid Chromatography. ) Toxicity to aquatic organisms. 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 . 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 . Unlike the insecticidal carbamates, it has no effect on cholinesterase activity. In the new specification the minimum purity of propiconazole is 96.0 % (by weight). El-Saeid ([16] – refer to Table 1) monitored pesticide residues in canned foods, fruits, and vegetables, obtained from a local market in Houston, Texas. Propiconazole is not an eye irritant in rabbits, but it is irritating to rabbit skin and a skin sensitizer in guinea pigs. In addition, based on their chemical structure there is no need to believe that they would be more toxic than the active substance itself. Rats in repeated-dose studies with metalaxyl-M developed centrilobular hepatocellular hypertrophy. ([15] – refer to Table 1) worked on the enantiomeric separation of six triazole fungicides, namely, cyproconazole, propiconazole, diniconazole, hexaconazole, tebuconazole, and tetraconazole. Therefore, propiconazole may contaminate aquatic ecosystems through off-site runoff under heavy rainfall when soil erosion occurs. This study assessed the effects of long-term exposure to PCZ on the antioxidant defense system and Na(+)-K(+)-ATPase activity of rainbow trout brain. Label elements: Pictogram: GHS07 exclam exclam The degree of bioactivity and acute toxicity of the propiconazole stereoisomers differed depending on the type of target pathogens and non-target organisms. Therefore, propiconazole may contaminate aquatic ecosystems through off-site runoff under heavy rainfall when soil erosion occurs. However, it is a severe eye irritant and moderately toxic if inhaled (rat LC50 0.094 mg/L). 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. Ramesh C. Gupta, James W. Crissman, in Haschek and Rousseaux's Handbook of Toxicologic Pathology (Third Edition), 2013. The major concern with EBDC pesticides (also including maneb and metiram) is the major metabolite, ethylene thiourea (ETU), as it is a major environmental degradant and minor contaminant. Propiconazole is a triazole fungicide that has been widely used in agriculture and has been detected in the aquatic environment. Despite its MOA in fungi, studies of mammalian carcinogenicity, cytogenicity, mutagenicity, teratogenicity, and reproduction were all negative. Propiconazole is a conazole, classified by FRAC as a demethylation inhibitor. The persistence hazard of propiconazole is rated high. For example, in the rodent forestomach it is an irritant, causing inflammation, hyperplasia, hyperkeratosis, and eventually papillomas and carcinomas. Biotransformation is an important route of transformation, with major transformation products being two compounds hydroxylated at the dioxolane moiety. H400: Very toxic to aquatic life. The rat oral LD50 is 670 mg/kg for both formulations. It is a mild skin irritant and sensitizer, and a mild to moderate eye irritant in rabbits. Propiconazole is not a mutagen, teratogen, or reproductive toxicant. Chemically, it is a polychlorinated aromatic, classified by FRAC as a chloronitrile/phthalonitrile. The toxicity database for propiconazole is complete. Chronic studies of mice ingesting thiophanate-methyl at up to 8000 ppm in their diet revealed higher liver weights and hepatocellular hypertrophy. Therefore, exposure of aquatic organisms to these low mobility pesticides, in many cases, will coincide with a high sediment concentration. Very toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment. The ratios on isomers fit within Propiconazole (PCZ) is a systemic foliar fungicide with a broad range of activity. Propiconazole is very soluble in water. The rat oral LD50 is > 10 000 mg/kg (i.e., it is practically non-toxic). 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. Both are non-irritating and non-sensitizing for skin. 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. List of chemicals in the same family, including breakdown products, salts, esters, isomers, and other derivatives. Do not contaminate water when disposing of equipment washwater. All the tested foods had different levels of pesticide residues ranging from 0.03 ± 0.005 to 0.8 ± 0.12 ppm. Mancozeb is an ethylene bisdithiocarbamate (EBDC), part of a very widely used thiocarbamate class that generates multisite fungicidal activity by complexing with and inhibiting metal-containing enzymes, including those involved with the production of ATP.
