Barium sulfate is generally non-toxic to humans, and barium sulfate belongs to insoluble deposits that are not digested in the body and excreted. In the hospital to do gastric examination, it is the use of barium sulfate non-toxic to the human body. In addition to barium sulfate, some other soluble barium salts or barium salts that react with gastric acids are harmful to humans, because heavy metal ions can destroy human proteins and impede the normal biochemical response of the human body. Barium sulfate insoluble in water, insoluble in sulfuric acid, hydrochloric acid, nitric acid and other strong acids. Barium sulfate is used as a barium meal in human gastric juice, which contains low levels of hydrochloric acid. Taking barium meal as a contrast agent of gastroscope is basically harmless to the body. Barium carbonate must not be used because barium chloride is soluble in hydrochloric acid to produce highly toxic barium chloride, which causes death.

　　硫酸钡防护措施：

　　Barium sulfate, protective measures:

　　1、硫酸钡无害，不小心溅到身上，用水搓洗即可。

　　1, barium sulfate and harmless, careful not to splash water to scrub.

　　2、长久工作在这样的环境，容易患职业病：尘肺。硫酸钡生产时，工人应该做好防护措施，配带劳保。

　　2, long-term work in such an environment, prone to occupational diseases: pneumoconiosis. Barium sulfate production, workers should do a good job of protective measures, with labor insurance.

　　3、在生产硫酸钡的时候，应该厂房密闭，防止粉尘污染坏境。

　　3, in the production of barium sulfate, the plant should be closed, to prevent dust pollution.

　　4、应该有伤害,但很小.硫酸钡是难溶物,有毒的钡无法电离,进而较难进入人体,但总有极微量的钡离子,会对人体造成伤害.医院给病人胃造影用的就是硫酸钡的悬浊液,伤害很小。

　　4, there should be hurt, but very small. Barium sulfate is insoluble, toxic and difficult to be ionized barium, into the body, but there is always a trace amount of barium ions, can cause harm to human body. The hospital for patients with gastric angiography is used in barium sulfate suspension injury is very small.
