In the aquatic environment, propiconazole is presented to be moderately persistent to persistent. Propiconazole has been reported to be stable in both aqueous and soil environments. endstream endobj 258 0 obj <>stream 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. However, it is a severe eye irritant and moderately toxic if inhaled (rat LC50 0.094 mg/L). We use cookies to help provide and enhance our service and tailor content and ads. May cause sensitization by skin contact. First published in the EFSA Journal: 12 July 2017. Unlike the insecticidal carbamates, it has no effect on cholinesterase activity. Our findings therefore highlight the risk of reproductive toxicity in amphibians as a consequence of developmental exposure to azole pesticides and other aromatase inhibitors. All the tested foods had different levels of pesticide residues ranging from 0.03 ± 0.005 to 0.8 ± 0.12 ppm. The rat oral LD50 is 670 mg/kg for both formulations. Chronic toxicity to aquatic Invertebrates Picoxystrobin : NOEC/21 d/Daphnia magna (Water flea): 0.008 mg/l Propiconazole : NOEC/21 d/Daphnia magna (Water flea): 0.31 mg/l Repeated high-dose exposure of rodents causes hepatocyte hypertrophy and necrosis. Liver adenomas have been observed in female mice. ([15] – refer to Table 1) worked on the enantiomeric separation of six triazole fungicides, namely, cyproconazole, propiconazole, diniconazole, hexaconazole, tebuconazole, and tetraconazole. In another example, Triclosan, which is used as in-can preservative (e.g., cosmetics), as a disinfectant, and in the treatment … In addition, based on their chemical structure there is no need to believe that they would be more toxic than the active substance itself. 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. 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. 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).

Hepatic enzyme induction produced secondary effects on the thyroid, probably attributable to increased thyroid hormone catabolism. 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 . 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. %PDF-1.6 %���� propiconazole for reproductive toxicity in category 1B leading to a critical area of concern concerning approval criteria and the relevance of groundwater metabolites. The combined effects of propiconazole and suspended sediment are dependent on concentrations of sediment and propiconazole. GEORGE N. AGRIOS, in Plant Pathology (Fifth Edition), 2005. 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. Propiconazole has been detected, but has a low detection frequency. Pawan K. Gupta, in Reproductive and Developmental Toxicology (Second Edition), 2017.

Rats in repeated-dose studies with metalaxyl-M developed centrilobular hepatocellular hypertrophy. 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). 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). In dogs treated daily for 2 years with up to 80 mg metalaxyl/kg, high-dose dogs showed transient spasms and salivation, especially during the first year, and four high-dose dogs died between study weeks 20 and 52. The ratios on isomers fit within Therefore, propiconazole may contaminate aquatic ecosystems through off-site runoff under heavy rainfall when soil erosion occurs. Ramesh C. Gupta, James W. Crissman, in Haschek and Rousseaux's Handbook of Toxicologic Pathology (Third Edition), 2013. proposal was withdrawn in 2011 as a result of receiving new data on aquatic toxicity. This agent has antibacterial and antiviral qualities as well. The fungicide affected a mixed natural population of fungivorous flagellates less than the population of bacterivorous flagellates. 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. Biotransformation is an important route of transformation, with major transformation products being two compounds hydroxylated at the dioxolane moiety. However, propiconazole can … They are applied as foliar sprays and as seed and soil treatments. Propiconazole depurates rapidly; thus, bioaccumulation is not expected to be a major concern for propiconazole. Persistence and degradability Water DT50 days Chemical Name Propiconazole:5.4 Soil DT50 days Chemical Name Propiconazole has a log Kow of 3.65 and the bioconcentration factors (BCFs) range from 24 to 516 times in fish tissues. Avian toxicity: ( Propiconazole technical ) Practically non-toxic. Pawan K. Gupta, in Veterinary Toxicology (Third Edition), 2018. The fungicide affected a mixed natural population of fungivorous flagellates less than the population of bacterivorous flagellates. SFE was used to extract the pesticides from the samples, which were then analyzed by SFC. El-Saeid ([16] – refer to Table 1) monitored pesticide residues in canned foods, fruits, and vegetables, obtained from a local market in Houston, Texas. Type: Reasoned Opinion. 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 combined effects of propiconazole and suspended sediment are dependent on concentrations of sediment and propiconazole. The conazole class of fungicides includes cyproconazole, diniconazole, triadimefon, triadimenol, propiconazole, and imazalil and has low to moderate acute toxicity. In the new specification the minimum purity of propiconazole is 96.0 % (by weight). 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. Mancozeb is a polymerized mixture of zinc and manganese salts of the organic molecule. In another example, Triclosan, which is used as in-can preservative (e.g., cosmetics), as a disinfectant, and in the treatment of textiles, is very toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment, is irritating to eyes, and is irritating to respiratory systems.

May cause sensitization by skin contact. ECOTOXICITY DATA: Data presented below is on the propiconazole technical product. Propiconazole degrades to 1,2,4-triazole, which has a half-life of about 500 days (Reference 1). Combined effects of the fungicide propiconazole and agricultural runoff sediments on the aquatic bryophyte Vesicularia dubyana - Wu - 2005 - Environmental Toxicology and Chemistry - Wiley Online Library Propiconazole is a chiral fungicide used in agriculture for control of many fungal diseases on a variety of crops. Therefore, propiconazole may contaminate aquatic ecosystems through off-site runoff under heavy rainfall when soil erosion occurs. This compound is a phenylamide that disrupts fungal RNA polymerase, and the R-enantiomer is much more active. List of chemicals in the same family, including breakdown products, salts, esters, isomers, and other derivatives. 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. 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: Read it on the Wiley Online Library: Article | PDF. 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. Toxicity to aquatic organisms. Éviter de contaminer les systèmes aquatiques pendant l’application. 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. Triadimenol is nonirritating, whereas technical-grade triadimefon is sensitizing. ETU is a goitrogen, which interferes with thyroid peroxidase. For example, in the rodent forestomach it is an irritant, causing inflammation, hyperplasia, hyperkeratosis, and eventually papillomas and carcinomas. Biocidal products can often contain substances of concern with allergic, ecotoxic, carcinogenic, developmental neurotoxic, or endocrine-disrupting properties. r��$���N��G#n�g;��q���ժ��*�e��Y���x� !G��l؉��{�>F��&��ؗ�b�%w�����̪m���?�tl���_�9�Rxn��n���� P2�,l�m���V�(i��8�0s�U� PROPICONAZOLE EMULSIFIABLE CONCENTRATE (JUNE 2019) 5 PART TWO EVALUATIONS OF PROPICONAZOLE 8 2018 FAO/WHO EVALUATION REPORT ON PROPICONAZOLE 9 SUPPORTING INFORMATION 11 ANNEX 1: HAZARD SUMMARY PROVIDED BY THE PROPOSER 17 ANNEX 2: REFERENCES 29. Aquatic Toxicity (Acute), Category 1 Aquatic Toxicity (Chronic), Category 1 2.1 Classification of the Substance or Mixture: H302: Harmful if swallowed. Dogs dosed at 250 mg/kg/day for 2 years had increased thyroid weights. The potential endocrine disruption of propiconazole was identified both as an issue that could not be finalised and a critical area of concern. A total of 39% of foods tested were found to contain four pyrethroids, four herbicides, four fungicides, and six carbamates in different food samples. List of chemicals in the same family, including breakdown products, salts, esters, isomers, and other derivatives. 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). It’s less mobile in soil, and a relatively low toxicant to birds and bees. 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). Related Chems. Propiconazole is a triazole fungicide that has been widely used in agriculture and has been detected in the aquatic environment.
