代谢
溴主要通过吸入进入人体,但也可能通过皮肤接触。溴盐可以摄入。由于溴的活性,它会迅速形成溴化物并可能沉积在组织中,取代其他卤素。银化合物也可以通过口腔和皮肤吸收。它通过血液分布到全身,尤其是肝脏。不溶的银盐转化为可溶的银硫化蛋白盐,与RNA、DNA和蛋白质中的氨基或羧基团结合,或者被抗坏血酸或儿茶酚胺还原为金属银。金属银被氧化,可能会沉积在组织中,导致银质沉着病。银主要通过粪便排出体外。
Bromine is mainly absorbed via inhalation, but may also enter the body through dermal contact. Bromine salts can be ingested. Due to its reactivity, bromine quickly forms bromide and may be deposited in the tissues, displacing other halogens. Silver compounds can also be absorbed orally and dermally. It distributes throughout the body in the blood, particularily to the liver. Insoluble silver salts are transformed into soluble silver sulfide albuminates, bind to amino or carboxyl groups in RNA, DNA, and proteins, or are reduced to metallic silver by ascorbic acid or catecholamines. Metallic silver is oxidized and may deposit in the tissues, causing arygria. Silver is eliminated primarily in the faeces. (L808, L626)
