Download file to see previous pages Metals are usually perceived to have positive effects on the human body, but metals are also very dangerous as they are poisonous when ingested in the body through breathing and oral intake. However, dangerous metals cans are beneficial to humans. It is also through metals that science was able to produce treatments for the various diseases that plague both children and adults.
Corrosives and metals and their salts are the two kinds of inorganic poisons. Corrosives are poisons that inflame ad destroy tissues. Their local action is the prominent clinical feature, and their general action from absorption is secondary. The corrosives include mineral acids, sulphuric, nitric, and hydrochloric; such powerful organic acids as oxalic, acetic, and carbolic; the alkaline corrosives; ammonia gas, and the halogens. Their action on tissue is to extract water, to coagulate proteins, ad to change hemoglobin into acid hematin. In a concentrated state, corrosives destroy the mucous membrane of the stomach, and they may break through the stomach or the esophagus to attack and destroy surrounding tissues and blood vessels. In such cases, death from shock ensues in a few hours.
Of mineral acids, sulphuric has the most extreme action, and it is never taken internally except in cases of suicide. Oxalic acid is sometimes taken internally by being mistaken as Epsom salts. Symptoms of poisoning are difficulty in swallowing, pain in the epigastrium, thirst, and vomiting, followed by coma, collapse, and death which may follow within a few hours or after several days. The antidote is chalk and magnesia. Phenol or carbolic acid is in the form of crystals slightly soluble in water. It is extremely poisonous. Lysol is like phenol in its effects.
Alkaline corrosives are a group of strong inorganic bases, such as hydroxides of sodium and potassium, lye, quicklime and ammonia water. In the body, they invade cells and form alkaline albuminates. Even in the dilute form, they cause severe inflammation, converting the stomach mucous membrane into a moist, swollen layer. ...Download file to see next pagesRead More
