毒理性
鉴定和使用:硫酸钠是一种白色粉末或晶体。它用于标准化染料,在冷冻混合物中,以及用于染料和印刷纺织品。它还用于人类作为泻药和通便剂,以及用于兽医药物。人体研究:可能导致胃肠道刺激和腹泻。动物研究:家禽在饮用含有7500毫克/升硫酸钠的水15天后,死亡率为33%。猪因过量服用导致的中毒爆发特点为抽搐、震颤和惊厥。尸检时最明显的病变是大脑皮层的广泛空泡化和坏死。生态毒性研究:植物受到土壤中4000毫克/升硫酸钠水平的伤害;710毫克/升抑制了根的生长和吸水。在淡水物种中,水蚤和贻贝对硫酸盐的急性敏感性高于摇蚊和胖头鱼,而胖头鱼对硫酸盐的慢性敏感性高于其他三种物种。
IDENTIFICATION AND USE: Sodium sulfate is a white powder, or crystals. It is used for standardizing dyes, in freezing mixtures, and in dying and printing textiles. It is also used as cathartic and purgative in humans and in veterinary medicine. HUMAN STUDIES: It may result in gastrointestinal irritation and diarrhea. ANIMAL STUDIES: Poultry mortality was 33% after drinking water containing 7500 mg/L sodium sulfate for 15 days. Outbreaks of poisoning in pigs due to overdosage were characterized by twitching, tremors and convulsions. The most noticeable lesion at post mortem was widespread vacuolation and necrosis of cerebral cortex. ECOTOXICITY STUDIES: Plants were injured by sodium sulfate levels of 4000 mg/L in soil; 710 mg/L depressed root growth and water absorption. Among aquatic species, the cladoceran and mussel were acutely more sensitive to sulfate than the midge and fathead minnow, whereas the fathead minnow was chronically more sensitive than the other 3 species.
