毒理性
识别:2,4,6-三溴苯酚是一种白色至几乎白色的结晶性粉末,具有类似苯酚的刺激性气味。2,4,6-三溴苯酚是合成阻燃剂的中介。2,4,6-三溴苯酚是在封闭的反应器中通过非水处理过程产生的,并以熔融和造粒的形式排出,以便于处理。它是最广泛生产的溴化酚。人类暴露:职业暴露于这种化合物可能通过吸入和皮肤途径发生。暴露于2,4,6-三溴苯酚会通过饮用水和食用海鲜。动物/无脊椎动物/植物研究:2,4,6-三溴苯酚在小肠中迅速被哺乳动物吸收,也通过尿液和粪便迅速排出。这种化合物对兔皮肤没有刺激性,但对兔眼睛有中等刺激性。它是豚鼠的皮肤致敏剂。在大鼠中进行的2,4,6-三溴苯酚的重复剂量口服毒性研究以及生殖/发育毒性筛选试验表明,两组动物的体重增加减少,绝对肝脏重量增加,血液中总蛋白、白蛋白、白蛋白/球蛋白比率和碱性磷酸酶(ALP)增加。两组动物都出现流涎,雄性大鼠的血液肌酐增加。在任何处理组中都没有观察到对动情周期、交配指数、生育指数、妊娠期持续时间、黄体数量、植入物数量、总仔数和活仔数、植入指数或分娩指数的负面影响。哺乳第四天的存活率和新生仔体重低于对照组。用两种类型的细菌进行的体外逆转突变研究均为阴性。一项体外染色体畸变试验在有和无代谢激活的情况下均为阳性。一项最高耐受剂量下的体内微核试验为阴性。在海洋环境中,2,4,6-三溴苯酚在原始软底栖息地中发现。包括2,4,6-三溴苯酚在内的溴化酚是由藻类、多毛类、半索动物以及海绵动物生物合成的。
IDENTIFICATION: 2,4,6-Tribromophenol is a white to almost white crystalline powder with an acrid odor like phenol. 2,4,6-Tribromophenol is an intermediate in the synthesis of fire retardants. 2,4,6-tribromophenol is produced in closed reactors by a non-aqueous processed and discharged as a melt and pelleted for easy handling. It is the most widely produced brominated phenol. HUMAN EXPOSURE: Occupational exposures to this compound may occur by both inhalation and dermal routes. Exposure to 2,4,6-tribromophenol would be trough drinking water and consumption of seafood. ANIMAL/INVERTEBRATE/PLANT STUDIES: 2,4,6-Tribromophenol is rapidly absorbed by the gastrointestinal tract in mammals and also rapidly excreted via the urine and feces. This compound was not an irritant to rabbit skin, but was moderately irritating to the rabbit eye. It is a skin sensitizer in guinea pigs. A combined repeated dose oral toxicity study with reproduction/developmental toxicity screening test on 2,4,6-tribromophenol in rats showed reduced body weight gain, increases in absolute and liver weights in both sexes, increases in total protein, albumin, albumin/globulin ratio and ALP in blood of male rats. Salivation was noted in both sexes and increase in blood creatinine was observed in male rats. No adverse effects were noted on esterous cyclicity, copulation index, fertility index, duration of gestation period, number of corpora lutea, number of imnplants, toat number of pups and live pups, implantation index, or delivery index in any treated group. Neonatal viability on day four of lactation was and neonatal body weights were lower than controls. In vitro reverse mutation studies with this compound in two types of bacteria were negative. One in vitro chromosomal aberration test was positive with and without metabolic activation. One in vivo micronucleus assay up to the maximum tolerated dose was negative. In the marine environment, 2,4,6-tribromophenol is found in pristine soft bottom habitats. Brominated phenols including 2,4,6-tribromophenol are biosynthesized by algae, polychetes, hemichordates along with marine sponges.[
