H400: Very toxic to aquatic life. Related Chems. Propiconazole partitions from water to soil or sediment quickly, where it is expected to be persistent under anaerobic conditions. 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: A total of 39% of foods tested were found to contain four pyrethroids, four herbicides, four fungicides, and six carbamates in different food samples. Toxicity to aquatic organisms. propiconazole, peer review, risk assessment, pesticide, fungicide. Propiconazole has been reported to be stable to hydrolysis as well as aqueous and soil photolysis. Metalaxyl is also negative for reproductive and developmental effects, and the great majority of genotoxicity tests have been negative. The conazole class of fungicides includes cyproconazole, diniconazole, triadimefon, triadimenol, propiconazole, imazalil, etc. List of chemicals in the same family, including breakdown products, salts, esters, isomers, and other derivatives. By continuing you agree to the use of cookies. It appears to phototransform slowly and is stable during hydrolysis. 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). Biocidal products can often contain substances of concern with allergic, ecotoxic, carcinogenic, developmental neurotoxic, or endocrine-disrupting properties. H410: Very toxic to aquatic life with long lasting effects. Very toxic to aquatic organisms, may cause long-term adverse effects in the aquatic … 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. The conazole class of fungicides includes cyproconazole, diniconazole, triadimefon, triadimenol, Hormone Metabolism and Signaling in Plants, Chromatography: Supercritical Fluid Chromatography. ) Therefore, exposure of aquatic organisms to these low mobility pesticides, in many cases, will coincide with a high sediment concentration. It was found that the organic modifier that provided the highest resolutions depended on the analyzed pesticide. Their high toxicity is synergized when co-occurring with azole fungicides in the aquatic environment. 257 0 obj <>stream Propiconazole 787 PROPICONAZOLE (160) First draft prepared by Dr Árpád Ambrus (Hungarian Food Safety Office), Ms T. van der Velde-Koerts and Dr B.C. 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). H317: May cause an allergic skin reaction. 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. ETU is a goitrogen, which interferes with thyroid peroxidase. You may be potentially affected by this action if you are an agricultural producer, food manufacturer, or pesticide manufacturer. A polysaccharide-based chiral stationary phase was used and the effect of different modifiers studied. Propiconazole has been detected, but has a low detection frequency. Propiconazole is a conazole, classified by FRAC as a demethylation inhibitor. proposal was withdrawn in 2011 as a result of receiving new data on aquatic toxicity. The rat oral LD50 is > 10 000 mg/kg (i.e., it is practically non-toxic). 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. 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.
