It was first detected by laboratories in Europe in 2011 [1] for imported black tea sourcing from China, India, and Sri Lanka [2]. Due to the anthraquinone detection in tea, European Union has set a maximum residue limit of 0.02 mg/kg for tea Europe [3]. This limit is a two order of magnitude lower compared to other pesticide residues in tea, and, thus, impacts the tea trade in Europe seriously. Anthraquinone is a possibly carcinogen to humans. Research has shown that this compound caused tumors in kidney, liver, urinary bladder, and thyroid gland of mammalian [4].

Human–Wildlife Interactions - 2019 - Application Strategy for an Anthraquinone-Based Repellent and the Protection of Soybeans from Canada Goose Depredation. Abstract Agricultural crops can sustain extensive damage caused by Canada geese (Branta canadensis) when these crops are planted near wetlands or brood-rearing sites.

From 2000 to 2015, South Dakota Game, Fish and Parks spent >$5.6 million to manage damages caused by Canada geese to agricultural crops (primarily soybeans) in South Dakota, USA. For the purpose of developing a repellent application strategy for nonlethal goose damage management, we comparatively evaluated the width of anthraquinone applications (i.e., 9.4 L Flight Control® Plus goose repellent/ha [active ingredient: 50% 9,10-anthraquinone] at 0–36 m versus 0–73 m perpendicular to the edge of wetlands in 2014), the timing of the first repellent application (i.e., 9.4 L Flight Control Plus goose repellent/ha at 50% versus 75% seedling emergence in 2015), the yield of soybeans (Glycine max) within repellent-treated and untreated subplots, and anthraquinone chemical residues in Day County, South Dakota.

ANSES - JUILLET 2011 - Origines et risques sanitaires liés à la présence d’anthraquinone dans les eaux destinées à la consommation humaine. Anthraquinone. Anthraquinone, also called anthracenedione or dioxoanthracene, is an aromatic organic compound with formula C 14H 8O 2.

Anthraquinone

Several isomers are possible, each of which can be viewed as a quinone derivative. The term anthraquinone, however, almost invariably refers to one specific isomer, 9,10-anthraquinone (IUPAC: 9,10-dioxoanthracene) wherein the keto groups are located on the central ring. It is a building block of many dyes and is used in bleaching pulp for papermaking. It is a yellow highly crystalline solid, poorly soluble in water but soluble in hot organic solvents. For instance, it is almost completely insoluble in ethanol near room temperature but 2.25 g will dissolve in 100 g of boiling ethanol.

Synthesis[edit] 9,10-Anthraquinone is obtained industrially by the oxidation of anthracene, a reaction that is localized at the central ring. Applications and natural occurrence[edit] Dyestuff precursor[edit] Anthraquinone. Un article de Wikipédia, l'encyclopédie libre.

Anthraquinone

L'anthraquinone appartient à la famille chimique des hydrocarbures aromatiques polycycliques. C'est un dérivé de l'anthracène. Présent à l'état naturel chez un certain nombre d'animaux et de plantes, il est aussi une substance active de produit phytosanitaire (ou produit phytopharmaceutique, ou pesticide), qui présente un effet répulsif à l'égard des oiseaux.

Isolé, il a l'apparence d'une poudre cristalline solide, du jaune et du gris-clair au gris-vert. UNIVERSITY OF NEBRASA 23/04/98 Anthraquinone protects rice seed from birds. ACTU ENVIRONNEMENT 20/09/11 Des hydrocarbures aromatiques polycycliques peuvent se former dans les canalisations d'eau.

Saisie de la question des risques sanitaires liés à la présence d'anthraquinone dans les eaux destinées à la consommation humaine, l'Anses recommande de développer une méthode de dosage des hydrocarbures aromatiques polycycliques (HAP).

Saisie en juillet 2010 par la Direction générale de la santé, l'Anses vient de rendre son avis sur les origines et les risques sanitaires liés à la présence d'anthraquinone dans les eaux destinées à la consommation humaine (EDCH). Cette saisine faisait suite au constat réalisé par les agences régionales de santé de Haute-Normandie et de Bourgogne de la présence d'anthraquinone dans certaines eaux destinées à la consommation humaine à des teneurs supérieures à la limite de qualité de 0,1 µg/l par substance individuelle de pesticide, alors que cette substance était absente de la ressource.
